What I'm looking for

I seek senior engineering roles building scalable web or cloud-native platforms with strong testing and CI/CD, collaborative teams, mentorship opportunities, and impactful product work.

I am a Senior Full-Stack Engineer with over 10 years of experience delivering scalable, high-performance web applications across e-commerce, healthcare, fintech, and finance. I specialize in frontend engineering and backend architecture, using modern JavaScript frameworks and Node.js to create dynamic, user-focused SaaS platforms.

At Primecodo and Deloitte I led design and implementation of responsive SPAs and robust backend services, built RESTful and GraphQL APIs, and deployed cloud-native solutions on AWS and GCP. I improved user engagement through performant UIs (React, Next.js, TypeScript) and optimized backend systems with microservices, caching, and message queues.

I emphasize testing, CI/CD, and mentoring—writing unit and integration tests, implementing pipelines, and guiding junior engineers. I continuously adopt emerging tech to solve complex problems and deliver reliable, production-grade software that drives business outcomes.
