At Scoremachine.ai, I migrate and optimize high-load backend systems in Go, including a legacy Python microservice that achieved a 20x speedup for 200k+ element batches.

I've scaled database-interactive TCP services from 20 to 2,500+ RPS, reduced RAM use by 44%, and built asynchronous workers for event-driven workflows with consistent cascading data transfer. I also implemented Redis-based rate limiting and token caching that eliminated API throttling timeouts during peak loads.

As a contractor at Google via Adecco, I replaced HTTP/REST microservice communication with gRPC and Protocol Buffers, reducing payload size by 63%. I built bounded Go worker pools for 10k+ concurrent connections and maintained 90%+ test coverage through TDD.

Across independent B2B projects, I've delivered web applications and e-commerce platforms end to end, from requirements and database design through production launch. I work autonomously in remote, international teams and build with Go, Python, microservices, CI/CD, and cloud infrastructure.
