Developed financial transactions and message processing (ISO 8583) with automatic conversions of more than 12 digital currencies and traditional currencies at the point of sale, letting users seamlessly spend their crypto and multiple currencies in real life, wherever Visa is accepted.

I served as a lead back-end developer on this project, where I integrated a new banking provider into an existing microservices infrastructure. Implemented SEPA and SWIFT payments based on the LHV banking partner. Delivered smooth transition of multicurrency individual IBANs for all active users.

Developed and delivered Stellar blockchain native integration with own issued Stablecoins transport and Fiat exchange support in just two months. I was involved in this project as an architect and back-end developer.

I've delivered strong customer authentication flow into the Wirex platform. Developed confirmation service from scratch to verify transactions according to PSD2 flow and verifying one-time passwords via SMS and two-factor authentication code.

According to the Payment Card Industry Data Security Standard, no sensitive data, like one-time passwords, was not stored on the own service database. Twilio Verify service was used for PSD2 and OTP support. I was responsible for integrating PSD2 and OTP into the platform, communication with the Twilio tech team, and back-end development of the new microservice.

Implemented an existing product's transition to the Azure cloud by rewriting the core components to use cloud-native storages for data backup and fast and scalable Azure Redis instances for the deduplication engine. I was in charge of the back-end development of the storage engine and deduplication engine.
