React Native
Architecture that scales, native modules when needed, the Expo toolchain, and offline-first data with WatermelonDB. I migrated a legacy monorepo to Expo and own the release process across iOS and Android.
Available for contract & full-time employment
Lead software engineer for mobile and connected products
I take mobile and connected products end to end — the React Native client, the backend APIs, and the cloud behind them. I've been the sole engineer on a 1M+ user app, designed Bluetooth device protocols from scratch, and led IoT security compliance. Bring me in to set technical direction, ship hard features, or get a connected product over the line.
Expertise
Mobile and connected products are my specialism — backed by full-stack and cloud ownership across the whole product lifecycle.
Bluetooth & IoT
BLE integration and device protocol design from scratch, with the spec co-owned by the firmware team. I led Ooni's first connected-product capability — real-time, bidirectional data between ovens and phones — and its IoT security compliance (ETSI EN 303 645).
Full-stack & cloud
Serverless APIs, Firebase and Google Cloud, AWS IoT Core, and data modelling for mobile sync. I build and own the backend the app depends on — including a zero-data-loss auth migration to Firebase.
Delivery & CI/CD
Mobile CI/CD pipelines and automated releases that keep delivery predictable, plus a Shopify-driven automation that ships new products with minimal app changes.
Accessibility
Inclusive defaults built in from the start — screen-reader coverage, contrast, and focus. I've delivered for users with dyslexia, visual impairments, and reduced motor skills.
AI-assisted delivery
I lead AI engineering enablement across the team, introducing tooling that lifts delivery speed and quality — always paired with human review on edge cases, security, and UX.
Selected work
Recent work across consumer hardware and assistive technology.
Ooni — smart oven companion app
After joining a small team, I quickly became the sole mobile and full-stack engineer on Ooni's React Native app (1M+ annual users). I architected Ooni Connect — their first Bluetooth integration — enabling real-time, bidirectional data between smart ovens and phones, designed a new BLE device protocol from scratch with the firmware team, and led IoT security compliance (ETSI EN 303 645). I built an offline-first platform on WatermelonDB and serverless APIs, migrated auth to Firebase / GCP with zero data loss, and replatformed a legacy monorepo to Expo and Netlify, for simple updates, and fast releases
Present Pal — accessible communication app
I was the senior React Native developmer for Present Pal, making public speaking more accessible for users with dyslexia, visual impairments, and reduced motor skills. I shipped consistent experiences across iOS and Android (phones and tablets), mentored a 4-person team — driving architecture and code review — and extended a PHP / Laravel backend to enable new features. Introduced unit testing in TypeScript and PHP with Jest.
How we can work together
A few ways I work with teams, depending on where your product is.
Lead Engineer
Ongoing architecture, reviews, and pairing — for teams that need senior engineering direction and a full-lifecycle perspective.
Project delivery
Scoped milestones from prototype to store submission, with clear handoff docs. I own the full stack when needed.
Advisory
Short audits on BLE reliability, IoT architecture, performance, accessibility, or release process — with actionable next steps.
