What I'm looking for

I seek backend-focused roles building scalable APIs and serverless systems, with collaborative teams, mentoring opportunities, and growth in architecture and DevOps.

I am a Senior Backend Node.js developer with seven years of experience building scalable REST APIs, serverless services, and data models across fintech, healthcare, e‑commerce and telecom projects. I design and implement backend architectures using Node.js, Express, NestJS, DynamoDB, MongoDB and SQL databases, and I coordinate closely with frontend teams to deliver robust, production-ready systems.

My recent work includes serverless AWS implementations and microservices for clients such as Millicom and Korn Ferry, automated CI/CD and Docker deployments, and mentoring junior engineers. I prioritize secure authentication (JWT/OAuth), coding standards, unit testing (Mocha/Chai/Jest), and performance troubleshooting to meet customer requirements.
