Find out what's slowing your app down — and fix it.

Before adding features or scaling, you need to know where your app stands. I perform deep technical audits on Flutter, FlutterFlow, and KMP apps to uncover performance bottlenecks, architectural debt, and security risks.
You get a clear, actionable report — not a vague list of "best practices." Every finding comes with a priority level and a concrete fix.

What I audit

Performance — render times, frame drops, memory leaks, battery drain, network efficiency
Architecture — state management, separation of concerns, testability, scalability readiness
Code quality — dead code, duplication, naming conventions, documentation gaps
Security — API key exposure, insecure storage, authentication flows, data encryption
Dependencies — outdated packages, vulnerability scanning, license compliance
Store readiness — compliance with latest Google Play and App Store guidelines

Who this is for

Founders who inherited a codebase. CTOs preparing for scale. Teams who feel their app is "slow but don't know why." Anyone about to invest in a major feature sprint and wants confidence in the foundation first.
