Debrief Notes — On-Device AI Voice Notes

2026 — In review

Self-initiated iOS · SwiftUI · Private by design

A local-first iOS app that records, transcribes, and summarises voice notes entirely on the device — no servers, no account, no cloud. Speech recognition and LLM summarisation both run offline. I extracted the AI layer into a reusable, open-source Swift package.

→ Fully on-device: recordings, transcripts, and summaries never leave the phone
→ On-device ASR (Apple SpeechAnalyzer + WhisperKit fallback) and Llama 3.2 3B summarisation via MLX-Swift
→ Open-sourced the AI service layer as a MIT-licensed Swift package (AIServiceKit)
→ Built on Swift 6 strict concurrency, SwiftUI, and SwiftData, iOS 18+

About

I design, build, and scale mobile and cloud-backed applications. Over a decade, I've taken products from idea to production across rideshare, healthcare, fitness, and accessibility domains — for clients in the US, UK, and Bangladesh.

I'm strongest where engineering meets product: turning vague business requirements into shipped systems, modernising legacy codebases, and getting small teams to deliver fast without cutting corners on architecture. Lately I've been building on-device AI on Apple platforms — running speech recognition and LLM summarisation fully offline.

Outside work, I volunteer as a Tech Tutor with LifeLines in Brighton and Hove, helping adults build digital skills.

Let's talk.
