- Data Warehouse and Reporting System Implementation
Our expertise in key technological areas enables us to develop and implement high-quality analytical solutions for our clients.
Data Science and Business Analytics
The amount of data we collect today is growing rapidly. We help our clients face that trend by using advanced scientific methods and technological solutions.
Applying data science implies specific knowledge and specific technologies such as artificial intelligence (AI) and machine learning.
We upgrade our existing expertise in practical business analytics with innovative, advanced algorithms that enable us to build and apply predictive models in projects whose overall goal is extracting full business value from big data.
Through internal projects at Koios, we support our employees as well as future young experts to develop skills and build knowledge in the fields of data science and business analytics.
Building a well-modeled data warehouse is imperative for every company processing large quantities of data from multiple sources and a prerequisite for quality business analytics.
Our key competencies are data integration through implementation of complex data models and business intelligence systems architecture.
We offer our clients what they often cannot get by applying ready-made models: understanding of their business field (i.e. the financial sector) and developing the model’s foundation according to their organization’s unique business processes.
Koios experts are certified specialists in Oracle, SAS, IBM (DB2, SPSS), and other tools in this area.
Custom Application Development
Companies and institutions in the financial sector have recognized the competitive benefits of developing their own, specific software business solutions as well as Koios expertise in the field.
We develop custom-made business applications whenever our clients require a unique functionality that is not part of a general purpose software or when significant savings can be made by developing a personalized solution, one entirely adapted to users’ needs as opposed to implementing a licensed software from a large supplier.
When developing applications, software engineers at Koios are fully capable of supporting you in two different technology stacks:
Microsoft’s .NET stack on one hand
and JAVA stack on the other hand;
providing clients with the best possible blend of technologies that fully suits their needs.
Applying modern software development methods and gaining expertise in the same enable us to develop custom applications with minimal resource costs. At the same time, we make maximum use of modern operating systems’ functionalities and develop multiplatform applications.
Frequently changing big data brings many companies and organizations up against a brick wall and leaves them asking themselves, “How to put the abundance of collected data to good use and recognize the ones carrying business value?”
Sometimes, the data is not even structured adequately, which makes it impossible to immediately apply some of our previously developed models of analysis.
In-house, Koios conducts a series of research projects focused on application of big data technologies and processing and analytics of large unstructured data.
In our R&D projects we focus on data storage, automated data processing, and real-time recognition of valuable and useful data, to best prepare ourselves for implementation of these processes into complex solutions for our customers.
The financial industry is facing the challenge of applying blockchain technology.
Due to specific advantages of the blockchain model, this technology can be applied anywhere where a firm and unambiguous confirmation of data authenticity by an institution of unquestioned authority is needed.
Our clients from the financial sector who base their businesses on reputation and authority are ideal for developing projects based on blockchain technology in the future.
Through several in-house research and development projects (R&D), Koios develops skills and knowledge of its employees in the field of understanding and applying blockchain technology in developing solutions and applications.
Atlassian Jira Consulting
Acquisition of Beta Tau Beta has brought over 15 years’ worth of experience in implementing Atlassian solutions, which makes us the most experienced Atlassian partner in the region; implementations ranging from SMEs with a couple of users to global corporations with over 10.000 users all over the globe. We have done implementations of practically every solution from Atlassian’s portfolio (Jira Software, Jira Service Management (ex. Service Desk), Confluence, Bitbucket, Trello, Fisheye, Crucible, Statuspage…) and are responsible for most implementations in the region, if not directly, then by educating, licensing or simply advising clients.
Best practices incorporated in Atlassian’s solutions, especially in ITSM, ITIL, or SDLC processes are implemented within our projects, thus helping our clients in modernization of their internal processes.
We are partners with all of the major Marketplace vendors which enables us to adapt the Jira solution precisely to the needs of the client while still maintaining key principles of Jira best practices.
We believe that key advantages to working with Koios are our professionalism and confidence, which we have proven to our clients in numerous projects. We love what we do, and that is why we are the best in what we do. Below is only a selection of projects for some of the leading financial institutions in Croatia and abroad.
Implementation and Maintenance of a Bank's BI System
The implementation and ongoing maintenance of the entire business intelligence (BI) system in a leading Croatian bank is one of the biggest Koios projects.
No matter the institution, but especially in financial ones, there are many challenges facing a BI system as it should continuously monitor all changes in all data sources, display the changes in a clear and accessible way, and offer the possibility to implement extra products and services easily at a user level.
With strong development of certain aspects of the financial industry, like mobile banking and mobile payments apps, many of these applications have become frequent users of banks’ analytical BI systems because they can offer additional services to their customers based on certain parameters.
Implementation of CRM Systems and Modules
Koios has implemented a Customer Relationship Management system in one of the biggest regional banking groups.
The aim of the implementation was to create a modern, advanced CRM system the bank could use in all the countries it operates in. Through the CRM system, the bank got a comprehensive overview of the existing assets of its clients and the products they use, enabling it to offer its clients additional products and create more efficient sales campaigns thanks to advanced methods of predictive analytics.
In addition, Koios is specialized for developing additional modules for existing CRM systems. In one of the leading Croatian banks we implemented a financial advisory system for clients based on information about their available financial assets. This CRM module enabled the bank to inform their clients about finances in a high-quality manner.
IFRS9 Implementation in Banks
Koios helped two major Croatian banks align their businesses and IT systems with the IFRS9 reporting standard. This regulatory standard (International Financial Reporting Standard) was implemented with the aim of tracking risky clients and protecting banks from over-exposure to credit risks.
Since aligning banks and financial institutions with the IFRS9 standard was required, many banks decided to purchase and implement external solutions. However, our experiences in developing and implementing our own solutions have resulted in our clients achieving not only high-quality reporting to the Croatian National Bank but a higher level of support to in-house teams in charge of credit risk assessments, too.
Credit Risk Assessment
We have participated in a couple of projects dealing with credit risk assessments. Financial institutions need this type of systems not only for aligning with regulatory obligations, but also for enabling the bank itself to calculate and assess its credit exposure to a certain client.
In addition, we have developed a data warehouse system for a credit information registry. The system included aggregating multiple source reports and developing predictive models that produced reports about trends in the entire banking market.
Implementing such solutions requires the experts at Koios to have a deep understanding of the ways banks operate, to be efficient at solving problems like insufficient or uneven data quality, and to cooperate with many different bank departments (including the IT and other business departments).
Money Laundering Prevention
Banks and other financial institutions must fight efficiently against money laundering, financing terrorism, and other criminal activities. They have to do it not just to comply with international and regulatory obligations, but to protect their own reputation as well. Identifying suspicious financial transactions requires advanced analytics over a large amount of data in real-time.
Koios has developed data collection architecture to support applications that track suspicious transactions and, thereby, prevent money laundering.
The application now successfully identifies high-risk transactions and notifies bank employees and departments who can then decide whether conducting further checks is necessary.
Banks and other financial institutions are mandatory to generate numerous reports to the Croatian National Bank and to regulators of main banks in other countries. At the same time, the banks have to be in alignment with international banking standards.
Because Koios participated in all the previous, major software deliveries and other IT support for a domestic financial regulator, we are thoroughly acquainted with the terminology, methodology of development, and comprehensiveness of requirements coming from this field.
Our applications for regulatory reporting are in full compliance with the complex methodology of making such reports. Koios’s support to clients is particularly valuable in this field because there are frequent changes in types or contents of certain reports. These changes demand the system and the application to be highly flexible.
Today, Koios team is made of over eighty experts with outstanding expertise in designing and implementing solutions for the financial sector. The head of Koios is constituted of a five-member board.
Stjepan Pavlek Posavec – Director, President of the Board
Stjepan Pavlek Posavec is one of the original founders of Koios. He is a business analyst and a business intelligence consultant with experience in a wide range of business areas. However, his main areas of interest are data science, data modeling, system integration, and analysis and development planning of IT systems.
Stjepan has significant experience working as a consultant in helping various organizations implement strategic initiatives and technical innovations, advance their skills and management, and transform their businesses. Moreover, he was in charge of many IT projects in banking. Regarding his international experiences, Stjepan began his career abroad even before he graduated from the Faculty of Electrical Engineering and Computing in Zagreb.
A European traveler. On his numerous business and private travels, Stjepan experienced the beauty and charm of life in 32 European countries. Prone to challenges and a natural adventurer, he once won a bet proving that it is possible to get from Zagreb to Estonia in four days by hitchhiking.
Ivana Dobrić – Board Member, Business Intelligence Consultant
Ivana is a board member and a business intelligence consultant with rich experience in developing IT systems for the banking sector. She took part in projects dealing with the implementation of credit rating models, regulatory requirements and reporting, data warehouses, and reporting systems.
Her experience encompasses analyses of business processes, data quality control, modeling of data warehouses, design and optimization of ETL processes as well as developing complex rule engine applications.
While in the office, Ivana is completely focused on solving clients’ problems. Outside the office, she is a passionate dancer and a big fan of long walks in nature that help her recharge her batteries. Her list of favorite things does not include junk food or things on wheels, so do not expect to impress her with either of the two.
Nino Surjan – Board Member, Business Intelligence Consultant
Nino is a business intelligence consultant with broad experience in the financial sector. His experience extends over many domestic and foreign projects in the banking industry with a strong emphasis on risk management and implementation of regulatory requirements.
Nino is well experienced in analyzing business processes, modeling, design, and optimization of ETL processes for data warehouses, and data quality control.

A software and hardware expert. He put together his second computer when he was just 13. You can only imagine what he can do today! When not feeding databases, he is feeding fish – Nino enjoys aquaristics. Once he solved a client’s emergency over a cell phone while sitting in a boat at sea, dressed in a diving suit.
Vlatko Malović – Board Member, Software Architect
Vlatko is a software architect and a developer on the .NET platform with extensive experience in software development using Microsoft technologies. Today, he mainly works on projects of implementation, optimization, and maintenance of complex business apps for the banking sector.

He is especially keen on introducing new technologies in existing information systems. Vlatko is another member of Koios team that graduated at the Faculty of Electrical Engineering and Computing in Zagreb.
A passionate Trekkie and a huge diving fan. Being the second generation of programmers in his family, he began programming already as a kid, messing around on the Qbasic code of the Gorillas video game. Today, programming is a game to him. On one occasion, he redesigned a system by making the calculations 1.000 times faster than before. Had not he been under such influence of his father, he would probably be a physicist today and spend his free time staring at the stars (as if he is not doing that already).
Vedran Vrbanić – Board Member, Business Intelligence Consultant
Vedran is a business intelligence consultant with comprehensive experience in the banking sector. His technical expertize is mostly related to data warehousing by using Oracle technologies. He worked on many projects as a programmer, system architect, analyst, team leader or mentor.

Vedran does not run away from challenges, business or sports ones. He once, while playing ball, scored eleven 3-pointers in a row! He likes to fix things around his apartment and on his scooter, loves Stephen King’s works, and enjoys reading popular science literature.
A network of associates in innovative teams enable us to continuously develop and implement innovations in all areas of business, and working with the Koios team is one of the finest examples of this cooperation.
The whole Koios team adapted to our situation and our needs exceptionally quickly. While reinforcing our internal development team, their programmers showed great expertise and flexibility. They enabled us to develop the system in one of our key projects in a timely manner. Koios proved to be a reliable and high quality partner, and our collaboration was excellent.
Their dedication to work and a deep understanding of the clients' needs, along with their proactive approach to solving current problems, are qualities which put the Koios team at the very top of the IT service sector. For me personally, it definitely is a team with which I would like to work again.
Being sincerely interested in our projects and having a deep knowledge of banking and banking regulations, Koios has become a reliable partner on our most important projects, and its consultants true members of our team.
