What I'm looking for

I seek a role building serverless/back-end systems with strong observability, CI/CD, and opportunities to own features and mentor others.

I am a software engineer focused on back-end development, primarily using Node.js and AWS serverless technologies to deliver reliable, performant systems. I emphasize ownership, clear communication, and impact-driven delivery across the full development lifecycle.

My recent work includes designing and shipping serverless architectures (Lambda, Step Functions, DynamoDB) and building REST APIs and event-driven workflows that improved performance and auditability. I have implemented observability with CloudWatch, vulnerability scanning in CI/CD (Trivy, Sonar), and enforced code quality through reviews and PR validation.

I bring practical experience in multiple stacks - Python/Django REST Framework, PostgreSQL, Golang, and front-end frameworks like Vue/Nuxt -and I’m comfortable working in GitLab CI/CD and containerized testing environments. I’ve driven measurable improvements such as doubling CSV/XLSX export performance and reducing incident response times with SMS alerting integrations.

Beyond engineering, I’ve led operational and rebranding initiatives, standardized supply-chain data, and contributed to team practices that improve consistency and delivery. I seek roles where I can continue building resilient systems, mentor peers, and contribute to high-impact, customer-facing solutions.
