I’m a CS undergraduate who shipped a live, payment-integrated e-commerce platform for a paying client in 5 weeks. I’m now focused on building distributed systems and ML infrastructure at project scale—where reliability, performance, and clean delivery matter.

As a freelance full-stack developer, I took a client from zero to a live e-commerce site solo, covering auth, cart, wishlist, and order-tracking across multiple product categories.

I integrated live-mode payments with KYC using Razorpay and closed tracked production issues end-to-end through client handoff, deploying on Vercel. In parallel, I build system-grade capabilities through projects like an edge-cloud orchestrator with Kafka event streaming and patterns designed to keep data consistent across services.

I also develop ML and computer vision pipelines, including disease classification and waste classification systems, and I care about making models usable in production via inference pipelines, scoring, and explainability.
