AI
AI pair-programming speeds up routine code, tests and docs. Your Mobile App Developer reviews every change and owns what ships.
Coding with an AI pair
GitHub Copilot, Cursor or Claude Code for boilerplate, refactors and first drafts. Every change is read and tested before merge.
Tests and edge cases
AI proposes test cases. Your Mobile App Developer runs them, fills the gaps and keeps the useful ones.
Docs and handover notes
READMEs, code comments and handover notes drafted with AI and checked against the code.
Debugging
AI helps read errors and logs. Your Mobile App Developer confirms the cause before changing anything.
Site copy and content
Page copy drafted from your brief, then checked for accuracy, SEO and accessibility.
Our rule: business-grade AI only, never free or personal accounts.
