What I'm looking for

I'm looking to build reliable, scalable backend systems where I can solve high-load and distributed-systems challenges, improve performance, and collaborate closely with cross-functional teams on maintainable products.

I've built backend services for gaming platforms along with promotions, leaderboards, jackpots, and player-engagement features. I design microservices using HTTP, gRPC, RabbitMQ, Kafka, and Redis to support low-latency, high-request workloads.

At Benivo, I developed HR-platform integrations that synchronize employee and organizational data, support onboarding and relocation workflows, and enable partner-specific configurations. At Volo, I built marketplace, driver, and logistics services covering order lifecycles, scheduling, refunds, Stripe payments, and distributed data reliability.

Earlier at Soft Construct, I designed ASP.NET APIs for partner integrations, migrated backend systems from .NET Framework to .NET Core, and improved risk-calculation SQL procedures to prevent long loading and deadlocks. My banking and AML background also gives me practical experience with transaction monitoring, risk controls, compliance, and operational reliability.
