Independent developer, six years in production. You design it, I build it. Front end, back end and the integrations in between, all white-label under your brand.
Most of my recent work is Web3, and the problems are the ones any consumer product has: checkout that cannot fail, launch-day traffic, payloads that have to stay small. Before that, payments with Stripe and Plaid, booking platforms and internal tools.

Campaign app where visitors claim a collectible without a wallet or a signup.
Rotating QR codes, rate limits and server-side checks, so a launch-day crowd could not game the randomised drop.

Toolkit that lets any app move assets between chains, framework agnostic. Built on a Web3 Foundation grant.
Finding a route, pricing it, signing it and retrying what fails, all behind a single call that works in any framework.

Buying, minting and trading across Polkadot and EVM chains, for the marketplace Chaotic replaced.

Solana app for private tips, invoices and paid content. Two wallets, so identity and funds stay unlinked.
Internal financial-planning platform for budgets, approvals, cost centres and reporting.
Personal-finance SaaS, with Stripe, Plaid and MethodFi integrations.
Game and admin features on AWS.
Booking platform for technical help, and the admin tools behind it.
Freight onboarding and tracking interfaces.
Your brand on the work, your name in front of the client. I join client calls as part of your team, or stay off them entirely.
Full overlap with European business hours, so a question in the morning has an answer the same day.
Code, repo, deployment and docs, handed over clean. Nothing depends on me still being there.
First job can be one page, or the bug nobody wants to touch. Fixed price, so you see how I work before committing to more.
I’m Hussnain, an independent developer. I’ve built marketplaces, payment flows, dashboards and internal tools, front end through back end. Most of that work is open source, so you can read the code before you hire me.
