What I'm looking for

I want to build and modernize AWS-based backend systems—Golang/Python microservices with strong observability, performance tuning, and scalable data pipelines—where I can own architecture, deliver measurable speedups, and collaborate with teams that value engineering excellence.

I’m a Senior Backend Software Engineer with 20+ years of experience building scalable, high-performance backend systems. I strongly specialize in Golang and Python within distributed microservices architectures deployed on AWS.

I focus on performance optimization, clean backend architecture, and measurable outcomes. I’ve reduced data processing time by 80%, improved Golang microservice latency by ~20%, and increased API performance by up to 8x after backend architectural refactoring.

My work spans robust API design (REST, gRPC, Protocol Buffers), advanced data modeling, and deep query tuning—cutting complex PostgreSQL query execution time by 70%. I’ve also led migrations such as Snowflake to Presto to improve performance and maintainability.

I operate comfortably across cloud-native infrastructure and observability, using AWS (EKS, ECS, Lambda), Docker/Kubernetes, and monitoring with Prometheus and Grafana. I bring disciplined engineering practices, including automated testing with >85% coverage.
