What I'm looking for

I'm looking for a role where I can help build something influential, take responsibility, solve real user problems, and continuously grow my technical and domain knowledge.

At Tranzzo, I build payment-provider integrations and microservices that support core payment processing. I also maintain and migrate legacy Scala services to Java.

I've automated workflow tasks, introduced a documentation-as-code approach, and developed AI workflows using agent skills and MCPs to improve developer productivity and simplify monitoring. I also contribute part-time to a donation platform for the Ukrainian army.

Previously at TheRaven, I integrated Stripe and crypto payments, refactored authentication, and set up monitoring infrastructure. I also built backend systems for graphics rendering and an internal HR platform from the ground up.
