AI Agent Developer & Fractional CTO | MCP, LLM, Flutter & React Apps

Hi, I’m Tom 👋 I build AI agents, MCP servers and AI-powered mobile & web apps for founders and growing businesses, and I’ve been doing this for 15+ years as a hands-on CTO with 160+ apps shipped. I’ve sat on your side of the table. I’ve founded companies, raised money, hired engineers and had to decide where every pound of budget goes. So I don’t just build what you ask for; I help you work out what’s worth building, then I ship it properly. Most AI projects die between the exciting demo and something your team trusts on a Tuesday afternoon. Closing that gap is what I do. 🤖 WHAT I CAN DO FOR YOU AI agents that do real work: agents that read your inbox, update your CRM, chase invoices, triage support, prep reports, and ask a human before doing anything risky. You get hours back every week. MCP servers & LLM integrations: connect Claude, ChatGPT or Cursor to your systems and data so your team can ask questions and get things done through AI instead of clicking through five tools. A “company brain”: one assistant grounded in your docs, database and processes, with proper permissions and sources. New hires ramp faster, nobody hunts for the answer twice. AI-powered mobile & web apps: Flutter and React/Next.js products with AI at the core, from MVP to App Store and scale. Fractional CTO: architecture, hiring, tech due diligence, and a plain-English answer to “should we even use AI for this?” 💡 WHY PEOPLE WORK WITH ME I think like a founder: director of Red Software Development Ltd, investor and advisor in 15+ startups, raised $1.5M+, built FounderBook and ZoomyRoom, co-founded Swivel (Antler-backed). I care whether this makes your business more valuable, not just whether it works. I ship fast without cutting corners: my team runs on Claude Code and Figma MCP, so you get senior-quality engineering at founder speed, with CI/CD, tests and docs as standard. I’m straight with you: if something’s a bad idea, I’ll say so before you pay for it. Software Engineering degree from a top-tier UK university; I still write code every day. I know your world: healthcare & care providers, marketplaces, events & booking, fitness, video & media, logistics, and internal tools for busy teams. 🛠️ STACK Claude API & Agent SDK, MCP, OpenAI, RAG · Flutter, React, Next.js · Node.js, Python · Supabase, PostgreSQL, AWS · GitHub Actions, Codemagic 🚀 HOW WE START Send me a few lines about what you’re trying to build or automate, or book a consultation. I’ll reply with the questions that matter, a recommended approach and a realistic first milestone, usually a short discovery sprint or one tightly scoped agent or MVP. Based in London 🇬🇧
