Your app is stuck, messy or not shipping?

I help founders and small teams fix, audit and ship Flutter and Android apps, and add the backend or AI feature they need, without hiring a full-time senior mobile engineer.

Sound familiar?

Six common blockers
Your app is stuck in development and users never see it.
Your developer left and no one owns the codebase.
You're about to launch and the store keeps rejecting you.
The codebase is getting messy and features are slowing down.
It's slow, crashes on some devices, or drains battery.
You need a senior opinion without committing to a full-time hire.

Few ways I can help.

Each starts with a focused call. You get a clear next step, not a vague roadmap.

diagnostic

Diagnostic Call

Who it's for: Founders who need a senior opinion on one problem

  • — 45-minute call on one problem: crashes, performance, build failures, store rejections or architecture
  • — I review your repo (read access) or problem statement before the call
  • — Written summary afterwards: root cause and a prioritised fix plan
  • — The $59 is credited toward any fix you hire me for

What you get: A clear diagnosis, and a quote if you want it fixed.

launch

Store Launch

Who it's for: Teams ready to release but blocked by the stores or the process

  • — Google Play and App Store setup, signing, metadata, privacy declarations and screenshots
  • — Rejection triage and a resubmission plan
  • — Release checklist and handover

What you get: A release-ready build and a repeatable release process. (Store approval is decided by Apple and Google; I get you to a compliant submission.)

audit

Architecture Audit

Who it's for: Teams growing a Flutter or Android app before costs rise

  • — Project structure, state management and data flow
  • — Offline behaviour, testing, CI/CD and release process
  • — Written report with the highest-impact changes ranked first, plus a walkthrough call

What you get: A prioritised plan your team can execute.

ai

AI Feature Sprint

Who it's for: Teams that want one useful AI feature in their mobile app, done properly

  • — One feature, for example document scanning, smart autofill or summaries
  • — FastAPI endpoint, LLM integration, and cost and latency logging
  • — Tested with real inputs before release

What you get: A working AI feature in your app, with its cost per use measured.

Launch pricing for my first 5 consulting clients, in exchange for an honest written testimonial. Scoping calls are free; scope and final price are agreed on the call. All prices in USD.

Why not just use AI?

AI writes code. It doesn't reproduce your crash on a real device, get you through store review, or own the result when the fix breaks something else. I use AI tools every day too, so you pay for 9 years of judgment and a working outcome, not for typing.

How it works.

Four clear steps
01Tell me what's wrong
02I assess it
03Fix, audit or ship
04You get a clear outcome

Paid sessions: payment details are emailed after booking, and the slot is confirmed once payment arrives. You have 12 hours to pay or the slot is released. Rescheduling is free up to 12 hours before; under 12 hours or a no-show is non-refundable. Scoping calls are free. All prices in USD.
