Software engineer with 5 years building and operating backend services on AWS. Comfortable across Go, Python, PostgreSQL, and Kubernetes, with a habit of writing tests, shipping through CI/CD, and instrumenting what I deploy. Took an order service from 99.9 to 99.97 percent uptime and cut p99 latency on the checkout path by 60 percent.
- Designed and shipped a Go microservice handling 4,000 requests per second, cutting p99 latency on the checkout path from 520ms to 210ms by adding Redis caching and connection pooling.
- Led the migration of a monolith to event-driven services on AWS (ECS, SQS, Lambda), raising order-service availability from 99.9 to 99.97 percent and isolating failures to single domains.
- Built the CI/CD pipeline in GitHub Actions with automated tests, linting, and blue-green deploys, taking mean time to production from 2 days to under 30 minutes.
- Raised test coverage on the payments service from 61 to 89 percent with Go table tests and integration suites, cutting production incidents roughly in half over two quarters.
- Built REST and gRPC APIs in Python (FastAPI) backing a logistics dashboard used by 30,000 daily users, documented with OpenAPI for three client teams.
- Optimized slow PostgreSQL queries with targeted indexes and EXPLAIN analysis, reducing a nightly batch job from 45 minutes to 7.
- Containerized eight services with Docker and Helm and wrote the Kubernetes manifests, smoothing local setup for new engineers from a day to under an hour.
- Added structured logging and Prometheus metrics across the request path, cutting mean time to detect production issues from 40 minutes to under 10.
