What I'm looking for

I’m looking for a role where I can lead headless eCommerce and platform architecture, drive performance (Core Web Vitals), and improve scalability and developer delivery through strong system design and CI/CD.

I’m a Senior Full Stack Engineer with 15+ years of experience building scalable eCommerce platforms and headless commerce architectures. I specialize in Java, React, Next.js, Node.js, Python, Laravel, Magento 2, GraphQL, and REST APIs—focused on system design, performance optimization, and distributed systems.

Recently, I designed a Magento 2 + Next.js headless architecture for 500K+ monthly users, built a Laravel-based API orchestration layer that reduced checkout latency (p95) from 400ms to 300ms, and improved Core Web Vitals (LCP 2.4s to 1.7s, FID 120ms to 85ms) using Redis, Varnish, and frontend optimization. I also lead teams and deliver high-traffic platforms, including CI/CD improvements and integration work across ERP, payments, and shipping, to reduce manual effort and boost conversion.
