What I'm looking for

I’m looking for a role where I can lead backend and distributed-systems engineering—building scalable REST APIs and event-driven architectures, improving performance/observability, and delivering maintainable enterprise software in an Agile team.

I’m a Senior Software Engineer with 6+ years building scalable web platforms, distributed systems, and high-performance backend services. I focus on concurrency, fault tolerance, asynchronous processing, and maintainable enterprise software design, with strong expertise in Go, Rust, and modern API engineering.

I’ve architected and shipped RESTful APIs and event-driven architectures using clean, SOLID-based designs, CI/CD pipelines, and containerized deployments on AWS. In my most recent work, I reduced API response times by ~40% through SQL optimization, indexing, caching, and middleware improvements, while improving observability with structured logging, tracing, and standardized responses.
