About me

Engineer by craft,
problem solver by nature.

I'm a Senior Full Stack Engineer with 5 years building production-grade SaaS. I specialise in React, Node.js (NestJS / Express), and cloud platforms including GCP and AWS.

My work spans fintech, smart pool management (IoT), and OTT platforms — each demanding a different approach to architecture and performance. I deliver measurable outcomes: 40%+ performance improvements and zero-miss sprint delivery.

Beyond engineering, I enjoy mentoring developers, leading technical client conversations, and contributing to system design decisions that define the product long-term.
