I will add a new feature to your existing mobile app

Working in someone else's codebase is a different skill from starting fresh. The goal is a feature that looks like your team wrote it. How I start: I read the code, run it, and send you a short note on what I found — including anything that will slow the work down. You decide whether to fix those first or work around them. Features I am often asked for: • In-app purchases and subscription handling • Push notifications with deep links into the right screen • Offline support and background synchronisation • Camera, media upload and file handling • Maps, location and geofencing • Third-party logins and payment providers Every feature ships with tests where your project has them, device testing across a real range of screen sizes and OS versions, and a pull request written to be reviewable — small commits, clear messages. If I see something dangerous while I am in there, I will tell you. Fixing it is your call, not a surprise on the invoice.
