About

Building mobile experiences that matter

I've spent the last decade building mobile apps that actually get used — banking platforms that process millions of transactions, social apps that people open every day, and messaging tools that have to work flawlessly. My main tools are React Native, Swift, and SwiftUI for mobile, with Elixir and Phoenix Framework on the backend when I need something that scales without drama. I'm the kind of developer who cares about the 1% of edge cases just as much as the happy path, because that's usually where trust is won or lost. Outside of client work, I publish open-source libraries used by developers worldwide and write about mobile engineering on Dev.to.

Experience

Where I've worked

Led a team building 4+ React Native banking apps for FIS's global clients — shipped features that moved real metrics: 30% lift in user engagement, 25% faster transaction processing.
Replaced a fragile legacy state layer with Redux Toolkit across multiple apps — performance up 40%, bug reports down by half. The kind of refactor that earns trust with product teams.
Migrated critical iOS codebases to React Native, cutting codebase complexity by 35% and finally letting the team ship to Android and iOS from a single repo.
Mentored five junior engineers with structured code reviews and pairing sessions — the team's output measurably improved, 20% more features shipped per sprint.
Rebuilt CI/CD pipelines on CircleCI and Fastlane from scratch — build times dropped 45%, daily releases became routine instead of stressful.

Shipped new checkout and product discovery features for a high-traffic e-commerce app in React Native — conversion rates climbed 28%, retention improved 15%.
Drove test coverage from 60% to 95% by introducing integration testing standards the whole team adopted — post-release defects dropped 40%.
Partnered with UX to rebuild the app's navigation and accessibility — App Store rating went from 3.8 to 4.6 in two release cycles.
Instrumented the app with performance monitoring tooling, hunted down the biggest bottlenecks, and cut load times by 35%.

Architected and shipped a cross-platform inventory management system in React Native — clients reported 50% fewer stockout incidents after go-live.
Designed a real-time sync engine using WebSockets with offline-first logic — data conflicts fell by 80%, and the app became genuinely usable in poor network conditions.
Cut the app bundle size by 40% through dependency auditing, code splitting, and asset optimisation — download and update completion rates improved substantially.

🏆"Magnificent Multi-tasker" award — recognised for delivering multiple high-priority projects simultaneously, consistently ahead of schedule.

Delivered a flagship retail iOS app from kickoff to App Store — mobile sales grew 200% in the first quarter, exceeding every stakeholder target.
Introduced protocol-oriented programming and FRP patterns to the codebase — complexity reduced 30%, and the team finally had patterns everyone could reason about.
Established code review and pair programming culture across a team of three iOS engineers — bug density fell 45% over two quarters.
Designed a modular app architecture that allowed parallel development tracks — new features reached production 35% faster.

Built and launched 5+ iOS applications in Swift, including a professional messaging app that crossed 500,000 downloads in its first year on the App Store.
Designed complex, animated interfaces using Auto Layout and custom animation rigs — user engagement metrics improved 40% vs the previous version.
Integrated RESTful APIs with smart caching strategies — server load dropped 30%, and the app felt fast even on slow connections.
Contributed to a proprietary IoT framework enabling seamless communication between iOS devices and smart home hardware.
