What I do.

01 / Capabilities
/ 01

Ship mobile apps.

Flutter-first, native iOS and SwiftUI when the platform calls for it. I write the production stuff: animations, offline state, push, in-app purchase, App Store and Play submissions. Fifteen apps in, and counting.

Wire up the AI.

Claude, GPT, embeddings, agentic flows. Streaming responses, prompt orchestration, tool use, vector search. DreamyBot's whole AI stack (100k+ users) was built by one engineer. Me.

Own the backend.

Node.js, FastAPI, Postgres, Firebase. The rare combo founders look for: the person who builds the app also builds the API it talks to. You don't need to hire a second engineer for v1.

Common questions.

04 / FAQ
  • Can you ship the mobile app and the backend, or just one?

    Both. I write the mobile app in Flutter or SwiftUI, the API in Node.js or FastAPI, and the AI layer (Claude, OpenAI) on top. Most of my recent work has been all three at once. DreamyBot was 100k+ users on Flutter, FastAPI, Python, and Node, shipped solo.

  • What's your timezone overlap with EU and US teams?

    Lahore is GMT+5. Five hours of overlap with most of Europe, three with US East Coast, and async with US West Coast. Standups work, async PRs work, and I reply to first messages within 24 hours.

  • Do you ship real AI features, or just chat wrappers?

    Real ones. Streaming LLM responses, prompt orchestration, tool use, vector search, eval pipelines. DreamyBot's AI stack handles 100k users with prompts versioned in the repo and one eval suite per prompt. Monetiza uses Claude in production for transaction categorisation.

  • Full-time or contract?

    Either. I'm looking for one full-time engagement at a time with a startup in the EU, US, or Canada. I'll also take long-term contracts (six months or more) for the same kind of work.

  • How quickly can you start?

    Within two weeks of an offer. Sooner for contracts that don't need offboarding from a current engagement. I don't take more than one full-time role at a time, so when I say yes, I mean it.

More questions

Should my next mobile app be Flutter or React Native?
I've rewritten two production apps from React Native to Flutter and shipped both faster after the rewrite. Flutter's hot reload, widget composition, and rendering performance pay off after the first month. I'll pick RN for a thin shell, but for anything with non-trivial UI I find it becomes a tax.
Can you build native iOS in SwiftUI when a project needs it?
Yes. I've shipped SwiftUI components inside native iOS apps and contributed to native codebases when projects need platform-specific work (CarPlay, complex audio, deep iOS integrations). Most of my work is Flutter because most projects don't need native, but I pick native when the project calls for it.
How do you handle in-app purchases and subscriptions in Flutter?
RevenueCat with server-side receipt validation, never client-only. I've shipped subscription stacks for Monetiza (4.8-star App Store rating, 11x revenue growth in year one) and DreamyBot (4.7 on iOS). The Flutter-for-fintech post in /writing covers the architecture in detail.
Do you use Claude Code, Cursor, and Codex in your daily workflow?
Every day. I ship 2 to 3 times faster because of it. I write the prompts that get there, review every commit, and own the bugs that come out. The AI tooling is a multiplier on a senior engineer, not a replacement.
How do you make AI features feel responsive in a mobile app?
I stream the model's response token by token using server-sent events from FastAPI into a Flutter StreamBuilder. I don't reach for websockets unless the app actually needs bidirectional. The DreamyBot AI-stack post in /writing covers the approach with code samples.
How do you keep AI features reliable as they evolve?
I version prompts in the repo, never in a database, so roll back is git revert. I run one eval suite per prompt on every PR. I log every model response with a hash of the system prompt so I can debug a regression in week six instead of guessing.
Have you shipped HIPAA-aware apps?
Yes. Care Compass was a HIPAA-aware care-team coordination app with role-based access on a Firebase backend, Stripe billing, and deep-linked patient invites. I know what to do and what not to do with PHI.
Do you require visa sponsorship?
Right now I have no work authorization for the EU, UK, US, or Canada. I'm open to sponsored roles. Most of the time I work remotely from Lahore, and that's the default arrangement I'm optimising for.
How do you keep code quality high while shipping fast?
I write tests. Unit tests on business logic, widget tests on the critical Flutter screens, integration tests on the subscription and auth flows, and eval suites on every prompt. I won't ship without them, and the AI tooling means I write them in the same loop instead of leaving them for later.
Do you do code handover?
Yes. I end every project with a README a new engineer can read in 20 minutes, an architecture diagram, and a walkthrough call. I don't leave repos that only I can maintain.

About.

06 / The facts

I'm a senior mobile and AI engineer based in Lahore. Five years writing apps, fifteen of them shipped, around half a million people using the things I built. I started on native iOS, moved to Flutter once it was clearly the right call for most of the work I take on, and picked up Python and Node when founders kept asking me to build the API too.

What I want now is one full-time engagement, remote, with a startup in the EU, US, or Canada, where I own the mobile product end to end. On a typical week that means the Flutter build, API contracts, and store releases in one thread. EU and US-East get morning overlap; US-West stays async with clear handoffs. I'd rather build one thing well than juggle four.
