As an independent Backend Developer, I developed backend components and integrated services for product teams working on an NFT marketplace, e-commerce websites, enterprise applications, and web games.

I'm developing Fitness Service, a Go microservice backend using PostgreSQL and Redis Streams. I implemented a transactional outbox for consistent event publishing, added graceful degradation and dependency health checks, and set up observability with Prometheus, Grafana, OpenTelemetry, Tempo, Loki, and Alloy.
