Frontend Engineering

I'm a Frontend Engineer dedicated to building high-frequency products with architectural rigor and immersive design.

My Journey

My journey in tech began with a rigorous academic foundation in B.Sc at the University of Mumbai, followed by intensive practical training at Masai School. This combination of theory and hands-on full-stack development gave me the confidence to tackle complex engineering challenges from day one.

At Pazago Technologies, I cut my teeth on building critical business tools. I engineered a global shipment tracking system and a real-time communication platform, learning the importance of performance optimization along the way—proudly boosting our core application's Lighthouse score from 56% to 94%. I also wore multiple hats, contributing to 'Precize', an investing platform where I built a secure high-volume wallet system.

My curiosity for specialized UI challenges led me to Hyperhire, where I dove into data visualization with D3.js and real-time AI integrations using Deepgram.

Currently at Porter, I operate at a massive scale, serving over 700K active users. My role has evolved from feature development to architectural stewardship. I've led the migration of our codebase from ReScript to TypeScript, implemented robust GitOps pipelines with ArgoCD, and optimized our geolocation services to reduce errors by 20%. Today, I focus on building systems that are not just functional, but resilient, scalable, and delightful to use.
