A natural-born team leader with the ability to build passion-driven, highly motivated teams of best-in-class programmers. An out-of-the-box strategist capable of smoothly communicating with business and flawlessly implementing ideas into a finished product.

I am a Co-Founder of Zenka Finance - a mobile short-term loan application launched in Kenya in December 2018 and downloaded since then more than 3 million times from the Google Play Store. Holding the position of CTO I had the pleasure to set up from scratch, motivate, manage and challenge the whole IT department (java developers, Android developers, iOS developers, UI/UX designers). I supervised the software development process of the distributed transactional system (gRPC, REST, Kafka), developed an alternative and unexploited channel for customers acquisition in Kenya basing on the USSD technology (resulting in 1.1M registrations), as well as built a custom ETL solution to support both the reporting and data analyst teams with data transferred to an aggregate DB from multiple sources in real-time using Write Ahead Log events and Kafka topics.

Developing a transaction platform for both shor-term and long-term loans. The product is used by an external customer. Personally, I built a team that works closely with various departments (risk, debt collection, accounting, customer service). We have migrated over a dozen or so milion records, including payments, payment distributions, ledger transactions, and customer data. I implemented and supervised the introduction of many key system functionalities, such as refinancing of loans, withdrawal from contacts, payment gateway and credit bureaus integrations.

Implementation of tools for the integration of job portals (www.totaljobs.com) and ATS platforms (https://en.wikipedia.org/wiki/Applicant_tracking_system)). The work took place in the client's office.

I helped in the construction of a new IT department in Poland (recruitment of new developers, introducing of new developers, transfer of knowledge from HQ). Implementation of many day-to-day features (API for financial brokers, payment gateway, etc.). Very advanced cooperations with business representatives.

I was a member of teams working in the telco sector. I worked on: eRefill platform for topping up prepaid accounts (telco operators in the Middle East), electronic activation of subscribe contracts (T-Mobile). I also made a significant contribution to the development and implementation of free internet data packges for roaming customers at the Cosmote Greece operator (the feature was deployed as a part of a billing system).

Implementation of a tool supporting the work of data analysts.
