I focus on API architecture, microservices orchestration, and cloud infrastructure automation. My code prioritizes observability, security, and performance to keep products growing smoothly.
I'm a Backend Engineer passionate about structuring system architecture, data, and automation. I believe a strong backend foundation is key to seamless user experiences while giving product teams room to scale.
I work extensively with Node.js, Go, PostgreSQL, and MySQL. I shape API designs, observability pipelines, and optimize infrastructure costs through automation and DevOps practices.
