I'm Paul. I build software.
I’m a product manager at Stripe, based in Dublin. Outside work, I design and build my own web and mobile apps, from the first idea to release.
These are a few of the things I’ve made.
Projects
RenzaWhat it isA publishing and collaboration tool for HTML documents, with shareable links, comments, version history and access controls.
The briefLet agents create documents in the format they work well with, while keeping the sharing and collaboration people expect from tools like Google Drive. Make the whole workflow accessible through the CLI and MCP.
WhackWhat it isAn iOS and Android app for exploring Irish property sales, bringing sale prices, floor areas and comparable homes together on a map.
The briefHelp first-time buyers understand what homes actually sell for, rather than relying on asking prices, so they can set a realistic budget before getting invested in a place.
Blossom SudokuWhat it isA Sudoku app for iPhone with 2,000 puzzles, guided technique lessons and a daily puzzle that works offline. No ads or accounts.
The briefRethink the Sudoku interface around a daily habit. Make entering numbers and pencil marks feel natural, with a minimal design that keeps attention on the puzzle and makes me want to come back.
Client work
About me
I like working through a product problem and building the solution. For my own projects, I handle the design, code and data infrastructure, with coding agents as part of my day-to-day workflow.
I’m based in Dublin, where I studied computer science at Trinity College.
Along the way
Stripe Staff Product Manager
2024–presentI work on billing, cost management and growth. Much of that involves helping businesses understand what they’re paying for and manage their relationship with Stripe.
CYGNVS Group Product Manager
2021–2024I joined as employee number seven and the first product manager. I helped build the cyber incident response platform and scale the company through its $55 million Series A, led by a16z.
Workday Product Manager
2017–2021I worked on enterprise products and developer tools. One project started as a two-person hackathon idea and grew into a digital adoption product supported by three teams.
Mayhem Tipperary Co-founder
2014–2017My dad was very entrepreneurial, and we started an obstacle course event together on our family farm in Tipperary. I handled sales, marketing, partnerships and the running of the business. Across eight events, we sold 5,000 tickets, and 40% of customers came back. RTÉ also filmed two episodes of Ireland’s Fittest Family at the venue.
