Product Engineer · Full Stack
Three products built end-to-end. Six infrastructure libraries open-sourced. Payments, storage, media processing, auth — the full stack, done right.
Selected work
Three products from scratch, six open-source libraries. Each one solved a real problem and taught me something I still use.
Seller-first digital storefront with payments, payouts, refunds, secure downloads, and multipart file uploads. Full commerce flow from product creation to buyer library access.
Platform connecting clients with videographers. Custom job requests, content library, FFmpeg background processing, resumable uploads to Cloudflare R2, and Razorpay payments.
Client-side browser tools for scan simulation, ink signatures, rubber stamps, photocopy effects, secure redaction, and metadata stripping. Canvas API rendering engines. Zero server uploads.
Open source
Resumable uploads, protected downloads, video processing, customer access, scan simulation, ink rendering.

About
“I build products the same way I want to use them — fast, reliable, and without unnecessary complexity.”
I'm a product engineer finishing my B.Tech in Automation and Robotics at GGSIPU. I've built three products end-to-end — StashQ, Vlynq, and ToolZap — covering the full stack: payments, storage, auth, media processing, and frontend.
I care about doing things right: idempotent payments, proper error states, server-controlled security boundaries, reusable adapter patterns. I write code that other engineers can extend, not just code that works today.
Beyond the three products, I've open-sourced six infrastructure libraries extracted from real production code. Resumable uploads, protected downloads, video processing, customer access, scan simulation, and ink rendering — all built from scratch, all solving real problems.
