Ways to work together
Not sure which fits? Describe the problem and we can work out the right shape together.
A long-term hire for a product team that needs someone to own mobile or full-stack work and raise the bar around them.
A defined piece of work with a clear outcome: a new app, a migration, an SDK upgrade, or a feature your team does not have capacity for.
For studios and agencies that want to offer native apps to their clients without building a mobile team.
Track record
The short version. The full CV has the rest.
Work in public
I write detailed, up-to-date guides on the stack I use every day, and I build small products on this site.
Practical guides written from real project work and kept current with each Expo SDK release.
App Store games, browser games, and product demos, built and shipped as working software.
Why me
From enterprise services and production support to sports tech, mobile apps, and modern product engineering. I have built things from scratch, taken over projects midway, and kept production systems running.
Irish and based in County Monaghan, with experience working across time zones in follow-the-sun delivery. Irish working hours overlap with the UK and Europe, and with US East Coast mornings.

Write maintainable code, integrate carefully, and keep the implementation honest against real usage.
Support testing, release, observability, and follow-up fixes so features land cleanly in production.
FAQ
Yes. I am looking for fully remote roles and contracts only, working from County Monaghan, Ireland. The time zone answer below covers how that lines up with your team.
Both. I am open to permanent senior roles, fixed-scope contracts, and ongoing partnerships with agencies that want to add mobile apps to their services.
I work on Irish time, which lines up with the UK and overlaps most of the European working day. I have worked in follow-the-sun setups with colleagues in the US, so the East Coast overlap works well.
React Native and Expo with TypeScript, backed by AWS (Cognito, DynamoDB, OpenSearch) or Firebase, with Sentry for monitoring. Before that I spent years in C# and .NET, and I have shipped native iOS features in Swift.
Yes. I offer a partnership for web teams that want to add iOS and Android apps to their services without hiring a mobile team. The mobile partner page explains how it works.
Yes. Taking over a project partway through and finishing it is something I have done before. I can also handle Expo SDK upgrades, migrations, and cleanup of fragile build and release setups.
