Rishav Kumar
Full-stack engineer building fast, real-time products for the web.
I care about the second after the click.
I'm Rishav — a full-stack engineer from Jamshedpur. I build products end-to-end: the interface, the API, the schema, and the performance work that makes them feel instant.
Most of my time sits between frontend and data — auth flows, search over large catalogs, caching, real-time streams. I'd rather ship a boring thing that holds up under load than a clever thing that doesn't.
I've shipped a trading platform pushing thousands of concurrent WebSocket updates, a CNN that identifies spoken language from raw audio, and CVora, an AI resume product of my own that's live today — with another MVP on the bench. Day-to-day I ship frontend architecture on live SaaS at WebbyWolf.
Shipped products, and the things I built to learn.
RoleDock
A job-hunt companion that tracks applications, keeps every document form-ready and reminds you before follow-ups slip — with your documents stored only on your own device.
LedgerX
GST billing, inventory and accounting for Indian businesses — a desktop app that works without internet and keeps every company's books on the user's own computer.
Huddle
A messenger with no phone number and post-quantum end-to-end encryption, where the server only ever sees ciphertext and forgets each message once it's delivered.
CVora
A resume builder with form-driven editing, AI job-tailoring, live preview and clean PDF export — built to be sold.
SK Enterprises
A marketing site for our family's manufacturing and trading business, built to give the company a fast, professional web presence and a clear way for buyers to get in touch.
Beyond these, I've architected and shipped several high-performance, proprietary web applications for various clients. I'm always happy to dive into the technical details and system design in a conversation.
Experience & education.

What I work with.
Everything listed here I've used in real, shipped work. Green dot = my core stack, used every day.
Commits, not just claims.
Certifications & awards.
Always learning. Easy to work with.
I pick up new technology fast and I enjoy it. Hand me a stack I haven't used and I'll be productive in it inside a week — that's how I got to Supabase, to WebSockets, to server-side rendering.
I adapt to how a team already works rather than asking it to change for me. New codebase, new conventions, new time zone — I'd rather learn the shape of things and be useful quickly than argue for my own preferences on day one.
Outside work the same instinct sends me travelling — Ladakh down to Kanyakumari, across Assam and Meghalaya, through Hyderabad, Bangalore and Nashik. And I'm learning guitar, which is a decent reminder that being bad at something new is the price of getting good at anything.
