At StrinovaHub, I designed, built, and run a live esports platform for Strinova. I migrated it from a NestJS monolith to 16 services on Kubernetes while players continued using it, and cut p99 latency by 71%.

I built its event backbone with Kafka (Redpanda), PostgreSQL, and protobuf contracts, and designed the private network connecting its services. I also automated delivery and observability with Forgejo CI, Argo CD, Prometheus, Grafana, Tempo, and OpenTelemetry.

I wrote ASH, an in-memory analytics engine in Rust, and a Rust parser that turns Unreal Engine replays into stats, positions, and heatmaps. The platform also includes tournament services, search, a Socket.IO gateway, image processing, a React app, and Discord and Telegram bots.

As a freelance Developer, I made websites and Telegram and Discord bots for clients, from requirements through deployment and support. I'm looking for full-time remote work or contract work in backend, platform, or infrastructure engineering.
