David D.

Ex Apple iOS Developer

🧠 I don’t just code — I lead builds to launch. 🔧 Complex apps. Clean handoffs. No noise. 💼 Apple-level quality, on your team. *** About Me *** I've worked as a senior iOS developer and technical lead for the last 14 years including working on an internal project at Apple. Previously I've worked on mobile apps across a number of different sectors with clients such as RBS, Sage, McDonalds, WIlliam Hill, and Roche / Genentech in the pharmaceutical space. More recently I've become specialised in Open AI (ChatGPT) having created the CodeBrain for Mac based on Open AI / Chat GPT. I'd be happy to look at taking on your mobile projects.
