At Sporty Group, I develop and maintain integrations that receive, process, and synchronize odds and market data for a sports betting platform. I also improve performance and reliability for high-volume live betting scenarios.

I implemented manual market settlement functionality and enhanced notifications for event-related issues and system incidents. I participate in a 24/7 on-call rotation, investigating and resolving production issues during live sporting events.

At Worldline(EGS), I developed an open-source Couchbase extension for Liquibase, including database versioning and migration capabilities. I also built an integration tool to retrieve transaction information from payment terminals and upload it to backend services.

Earlier, I developed an orders reporting tool from scratch at Worldline(EGS) and worked on payment-terminal and online payment systems. I’ve also taught Java SE at GITC.
