What I'm looking for

I’m looking for a remote, Agile team where I can build full-stack products end-to-end—shipping scalable Node/React features on AWS, improving performance and reliability, and mentoring others with high-accountability engineering.

I’m a Senior Full Stack Engineer with 13+ years of experience delivering scalable, maintainable Node.js and React solutions in remote, cross-functional Agile teams. I bring proven expertise in TypeScript and JavaScript, plus strong backend and database skills across PHP, WordPress, and SQL systems.

In my recent roles, I’ve architected full-stack features and serverless backends on AWS, using Lambda, API Gateway, SQS, and monitoring to reduce processing latency by 35% and cut MTTR by 50%. I’ve also integrated headless CMS platforms like Strapi and optimized PostgreSQL performance to reduce query response time by 40%, while applying Claude Code to improve engineering velocity by 20% and accelerate delivery.
