About

🚀 I’m a Principal Software Engineer & Founder with 7+ years of experience building AI-first products and scalable engineering systems. I specialize in Vibe Coding, MCP servers, and AI-connected development workflows that accelerate product delivery, reduce overhead, and unlock new business opportunities. Previously, I worked at Amazon, gaining hands-on experience in building and optimising large-scale distributed systems. Over the years, I’ve designed and implemented high-performance microservices, AI-powered integrations, and solutions that reduce manual effort and maximize business impact. 💡 What I do best: - Architecting and scaling backend systems (Ruby on Rails, Python, Microservices) - Driving AI adoption & automation for business growth - Product-first engineering: aligning tech decisions with business goals - Building tools that eliminate grunt work and let teams focus on what matters - Mentoring engineers & fostering high-performance teams - Beyond engineering, I actively shape product strategy, automation roadmaps, and AI-driven solutions to create impactful, scalable systems. Always open to discussing new ideas, collaborations, and innovations in tech! Let’s connect and build something transformative. 🚀
