What I'm looking for

I seek senior engineering roles building scalable full-stack or cloud-native systems, with collaborative teams, strong CI/CD, observability, and growth opportunities.

I am a Computer Science Engineer with over 20 years of experience building full-stack web, mobile, and enterprise applications, designing solution strategies, and driving product growth. I specialize in shaping service lines, architecting microservices, and integrating headless e-commerce systems.

My work blends front-end craftsmanship with robust backend and middleware development — NestJS microservices, Node.js, PHP, React/React Native and Next.js — while leveraging cloud platforms (AWS, GCP), containerization, and CI/CD to deliver scalable, observable systems.

I emphasize quality through TDD, observability (Prometheus, Grafana), and automation, and I adopt AI tools and modern UX tooling to accelerate delivery and improve user experiences.
