Your app is stuck, messy or not shipping?

I help founders and small teams fix, audit and ship Flutter and Android apps — 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.

Three 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 and teams who need a senior opinion on one specific problem

  • — 45-minute session on crashes, performance, build failures, store rejections or architecture
  • — Repo or problem statement reviewed before the call
  • — Written summary with root cause and a prioritised fix plan

What you get: A clear diagnosis, and a quote if you want me to fix it.

launch

Store Launch

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

  • — App Store and Google Play setup, signing and metadata
  • — Privacy declarations, screenshots and review guidance
  • — Rejection triage and re-submission strategy

What you get: A build that passes review and a release process you can repeat.

audit

Architecture Audit

Who it's for: Teams scaling a Flutter or Android app before it gets expensive

  • — Module and state-management review
  • — Offline, sync and data-flow analysis
  • — Testing, CI/CD and release-process assessment

What you get: A written audit with the highest-impact changes ranked first.

rescue

App Rescue

Who it's for: Founders whose app is stuck, crashing, or not shipping

  • — Diagnosis of the biggest blocker: crashes, bugs, performance or build issues
  • — Root-cause analysis of the biggest blocker
  • — A fix or a clear, prioritised fix plan

What you get: A stable path forward — whether I implement the fix or hand you a plan your team can execute. Best started with a Diagnostic Call.

Founding-client rate: 30% off for my first three clients, in exchange for a short written testimonial. Project scoping calls are free; scope and final price are agreed on the call.
