Hello
-
I'm Harish — a full-stack developer who's been building things on the web since 2021. Backends, APIs, databases — that's where I spend most of my time.
-
I figured out early that the fastest way to actually learn something is to ship it. Not tutorial it, not watch it — build it, break it, fix it.
-
I care about clean architecture and readable code — not because it looks good in a review, but because messy systems slow everything down and I've felt that firsthand.

Built and maintained production web applications — features, bug fixes, real deadlines. Got my first real taste of industry workflows and what it means to ship code that actually matters.

Upwork
Client work on the side. Real briefs, real deadlines, real feedback. The kind of pressure that makes you a better developer faster than any side project will.

A Chrome extension (Manifest V3) that fills forms with fake identity data instead of your real information. Also ships an encrypted local vault and disposable email inboxes via GuerrillaMail.
Zero analytics, zero telemetry, zero third-party trackers. The vault is AES-256-GCM encrypted — lose your password and your Secret Recovery Key and it's unrecoverable, by anyone.

A terminal clipboard manager. Copies text, files, or command output to the clipboard, keeps a local SQLite history, and lets you pin, search, share, or delete entries from the command line.
ocopy is the signature command — run anything, get its output on your clipboard, without breaking your terminal's live view of what's happening.
