How I can help

Senior engineering across product, platform, and delivery.

I am at my best where product expectations, technical constraints, and delivery pressure all meet.

Mobile and Web Apps

Build cross-platform experiences with React Native, Expo, and TypeScript, including apps that run on iOS, Android, and the web from one codebase.

Cloud Integration

Connect products to AWS services, Cognito authentication, DynamoDB, OpenSearch, and production monitoring with Sentry.

Firebase Backends

Auth, Firestore, Storage, Cloud Functions, App Check, and push notifications, with security rules and offline support done properly.

App Store Delivery

EAS Build and Submit pipelines, environment configuration, SDK upgrades, and getting releases through App Store and Google Play review.

Legacy Modernisation

Replace brittle systems, improve delivery workflows, and move older code toward maintainable architecture without disrupting production.

Team Foundations

Set up front-end architecture, code quality and testing processes, test automation, and help grow the team through hiring and onboarding.

Ways to work together

Permanent, contract, or partner. Pick what suits the work.

Not sure which fits? Describe the problem and we can work out the right shape together.

Contract

Project or build contract

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.

  • Greenfield Expo and React Native apps
  • Upgrades, migrations, and rescues
  • Clean handover and documentation
Agencies

Mobile partner for web teams

For studios and agencies that want to offer native apps to their clients without building a mobile team.

Track record

A decade of shipping, from enterprise .NET to modern mobile.

The short version. The full CV has the rest.

FAQ

Questions hiring managers usually ask.

Are you open to remote work?

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.

Do you take permanent roles, contracts, or both?

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.

Which time zones can you work with?

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.

What is your main tech stack?

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.

Can you work with an existing web team or agency?

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.

Can you take over an existing React Native or Expo app?

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.

What should I include in my first message?

What you are building, the current stack, whether it is a permanent role or a contract, the timeline, and where you need the most help. Rough notes are fine. The contact section below has a template you can copy.

Have a role or project in mind?

Send a short note to hi@paddyb.com. It helps to include:

  • What you are building
