I'm a full-stack engineer and technical leader with over a decade of hands-on experience building and scaling production platforms. My background is in PHP/Laravel and JavaScript/TypeScript, and I've worked across the full stack, from architecture and backend systems through to frontend with React and Vue. Most of my recent work has been at Ycode, where I joined early and led engineering from the initial 0→1 build through to a platform serving 30,000+ recurring users. That included a full platform rebuild which I ran as the primary hands-on engineer while leading the team, the project that pushed me fully into AI-native development workflows, using tools like Cursor and Claude Code to get a level of leverage out of a small team that simply wouldn't have been possible before. Alongside that I've worked on LLM integration in production at Outchat, and independently built and operated Raffaly, a skills-based competition platform I took from idea to over £100k in gross revenue entirely on my own, navigating payment processor failures and regulatory complexity along the way. I'm drawn to early-stage product companies where engineering shapes the product, ownership is real, and there's room to grow into broader technical leadership over time. I care about building things that actually work, that real people use, and that are done to a standard worth being proud of.
