What I'm looking for

I’m looking for a team where I can own backend architecture end-to-end—building scalable Node.js systems, strengthening reliability and security, and improving delivery speed through CI/CD—while mentoring engineers and partnering closely with product and DevOps.

I’m a results-driven Senior Node.js Developer and Backend Engineer with 7+ years of experience building scalable, high-performance systems at production scale.

I architect distributed workloads and optimize throughput, reliability, and responsiveness—using approaches like native worker_threads and careful PostgreSQL schema design. I’ve driven measurable improvements, including ~60% higher throughput under peak API load and ~35% faster queries on high-traffic endpoints.

I design secure, resilient cloud integrations—moving from long-lived credentials to zero-trust patterns with AWS STS AssumeRole, and tightening secrets and session handling with AWS Secrets Manager plus Redis. I also own CI/CD pipelines in Jenkins, improving deployment success rates (~30% fewer failed deployments) and cutting release time to under 20 minutes.

I lead by example: mentoring 2–3 junior engineers through code reviews and design sessions to raise unit test coverage (~20%) and reduce recurring production defects. I’m energized by teams that value performance, reliability, and cost-aware architecture in multi-tenant SaaS platforms.
