Available to hire
Hi, I’m a full‑stack software engineer who specializes in building robust Java/Spring, Node.js, and React applications. I design and ship REST APIs and serverless workloads on AWS, with a focus on migrations, integrations, and CI/CD hardening. I enjoy collaborating with clients to translate requirements into delivered solutions and reliable deployments.
I’ve led migrations and distributed systems work, improved logging and error handling, and developed integration and contract tests. I’m client‑facing and delivery‑oriented, committed to writing maintainable code and delivering value on time.
