About

Five years, six domains, one engineer who owns the whole thing

I'm a full-stack product engineer based in Lahore, working with international teams — startups and enterprises across Europe, the Middle East and North America. Five years in, I've shipped in fintech, healthcare, B2B e-commerce, HR, radiology and Web3, and led the teams that shipped alongside me.

I've built payment and KYC flows with real money moving through them, a medical-records platform clinicians use daily, and apps that reach iOS, Android and web from a single codebase. On the same products I've designed the schemas, written the services and integrations behind them, and owned the pipeline that put them in front of users — Stripe and Weavr for money, Auth0 for identity, Salesforce and One-Source for the supply chain.

I've rebuilt how I work around AI rather than bolting it on. Claude Code, Cursor, Windsurf and Codex sit in my daily loop — scaffolding, refactoring, reviewing, writing tests. It means a feature that used to take a sprint now takes days. What it doesn't mean is handing over judgement: architecture, review and what reaches production stay mine, and I can explain every line I ship.

I work async with US-morning or full EU-hours overlap and invoice as a contractor through Deel, Wise or Payoneer. If you need one person who can take a product from idea to deployed — and stay accountable for it — that's the job I do.

Services

What you can hand me

Six engagements, each one something already shipped on this page — not a menu of things I could try.

  • Idea to production

    Take a product from a blank repo to something real users are on — front end, back end and the pipeline between them.

    • Greenfield architecture
    • Web + mobile from one codebase
    • Shipped, not prototyped

  • AI operations & automation

    Put AI where it removes actual work: internal tooling, assisted workflows, and agentic pipelines that run without supervision.

    • Agentic workflows
    • LLM & MCP integration
    • AI-assisted internal tools

  • Payments & integrations

    Wire money, identity and third-party systems into a product without the compliance surface becoming someone else's problem later.

    • Stripe, Weavr, Auth0
    • Salesforce & vendor APIs
    • PCI-aware handling

  • Technical debt recovery

    Inherit a codebase that has stopped moving and get velocity back — refactoring with a plan, not a rewrite.

    • Audit and triage
    • Incremental refactor
    • Standards the team keeps

  • Design systems & platforms

    Build the shared foundation a team ships on: component library, patterns, flags, i18n, and the conventions that hold.

    • Component libraries
    • Feature flagging
    • Reusable boilerplates

  • Mobile delivery

    React Native apps that reach iOS and Android at feature parity with web, from a single codebase and one team.

    • iOS + Android + web
    • Store-ready delivery
    • Shared logic, native feel
