01 // about

From frontend developer to the person clients call first.

I started in 2019 as a React developer at Codebrahma. Eighteen months in, I joined a long-running project for an Ireland-based IoT company, and my role kept growing: from building screens to owning products end to end.

Today I gather requirements with the client, plan the work, build it, test it and ship it to the App Store and Google Play, working with design, backend, firmware and support teams. My roots are frontend; I'm just as comfortable in Node.js backends when a project needs it.

Fuel ordering platform

Lets households and businesses order heating oil online from their local distributor in the UK and Ireland. Customers find their address by postcode or Eircode, see prices with local VAT, and pay by card or on account. Each distributor gets a storefront in its own brand and an admin panel for orders, and customers can also order from inside the mobile app.

Customer and installer app

Started as a Bluetooth Low Energy app built from scratch and grew into the client's main mobile app, replacing an older WebView app. Customers see their tank readings, and installers use it to set up monitors over Bluetooth: the install flow, signal and network checks, firmware updates and activation. Built alongside the firmware team and released on the App Store and Google Play.
