About Me

I'm a Technical Systems Developer in Birmingham. By day I build business systems and workflow automation at Impacting Lives; alongside that I design and ship SubOn, my pickup football SaaS product - clean architecture, practical tools, and products that solve real problems.

How I Got Here...

I didn't start in tech, but I've always gravitated towards solving problems and building things from scratch. Software clicked as the place where curiosity meets creativity - the perfect marriage of my background as a Drama & Theatre graduate with years as a self-employed equities trader, where system design, iterative testing, and data-driven decisions were already part of the job.

I retrained at Northcoders in 2025, then moved into commercial work designing internal systems with JavaScript and Google Apps Script. Outside that role I founded SubOn - a full-stack SaaS platform for organising pickup football - taking it from architecture and auth through payments and deployment.

Earlier projects like Daily Spews, FoundIt, and SceneTogether taught me full-stack architecture, collaboration, and shipping for real users. Today I work across the stack - React, Next.js, Node, databases, and automation - always thinking about the person using the product and the developer who picks up the code next.

What I Do

Business Systems at Impacting Lives

Technical Systems & Support Administrator since September 2025. I design Google Apps Script automation, dashboards, and Google Workspace solutions that cut manual admin across HR, recruitment, and compliance.

Founder of SubOn

Building SubOn from concept to deployment - a pickup football SaaS platform with Expo, Next.js, Supabase, and Stripe. Join links, payment tracking, and Pro billing for organisers who are done with group chats.

Full-Stack Product Work

From React and Next.js frontends to Node APIs, PostgreSQL, and MongoDB. I care about clean architecture, maintainable code, and shipping tools people actually use - whether that's SaaS or internal systems.

Featured Projects

Here are some of my recent projects that showcase my skills in full-stack development, user experience design, and problem-solving.

SubOn

in progressMobile & Web Application

A pickup football organiser that lets players join via link or QR code, with built-in payment tracking for UK bank transfers.

SubOn is a mobile-first app I founded to take the admin out of organising casual football. Organisers create games, share a join link or QR code, and track who's in and who's paid - without handling player money through the app. Built as a pnpm + Turbo monorepo with native iOS/Android apps and a Next.js web layer for marketing, web-first join/pay, and Stripe billing for SubOn Pro.

Key Features:

Share join links and QR codes for instant player onboarding
Track RSVPs and payment status across your squad
Automatic team creation and game management tools
Web-first join and pay flow for players without the app
