🚀 I run three AI products of my own with paying subscribers, real search traffic and press coverage. So when I build for a client, I'm thinking about what happens after launch, not just what ships. That includes getting it found, whether that's Google or an AI assistant. ✅ 50K+ paying subscribers | 200K+ users served | 5.5K GitHub stars | £20M+ raised by a company where I was the founding engineer | 100% Job Success across 28 Upwork contracts | Top 2% on Upwork ━━━━━━━━━━━━━━━━━━━━ 🏗️ PRODUCTS I RUN ⚽ FPL Oracle — AI Fantasy Premier League assistant built on LangGraph, MCP servers and GPT. 5K+ paying subscribers, 300K+ search impressions and 5K clicks a month. Ranks page one for competitive FPL terms and gets cited by ChatGPT, Claude and Perplexity when people ask for FPL tools. Backlinked by established FPL publications. 80% of users finish in the top 10K out of 13M players. 📰 BackPage FC — AI football media platform. 10K+ clicks in the last 30 days, referenced across Google News and major publications. Revenue from partnerships and advertising, with publishers who let me distribute their content. Built for answer-engine visibility from day one, so AI models surface it when people ask about the stories it covers. 📄 SnapFile — AI document management with OCR, embeddings and retrieval. 30K+ users. REST integrations with Sage, Xero, QuickBooks, Google Drive and Dropbox. React, Node.js, PostgreSQL. ━━━━━━━━━━━━━━━━━━━━ 💼 WORK I'VE SHIPPED FOR OTHERS 🏠 Felicity at Lightwork AI — Founding AI engineer. LLM voice and chat assistant for property management with hybrid RAG and real-time VoIP at 600ms p95. Company raised £20M+ and was shortlisted for a UK PropTech Award. Started on a managed voice platform and rebuilt the call infrastructure on LiveKit once per-minute costs stopped scaling. 🤖 Databricks (contract) — Autonomous browser agents with LangGraph and Puppeteer for compliance research. Improved pricing accuracy by 11% and cut manual research time by 45%. Instrumented with MLflow. 💬 DialogFlux — Multi-tenant communication platform. Omnichannel inbox, AI sentiment analysis, real-time WebSocket dashboards. Processes millions of messages. ⭐ Open source — ML image restoration project with 5.5K GitHub stars, 80K+ downloads, cited in 50+ publications. Top 10 ML project on GitHub in 2022. ━━━━━━━━━━━━━━━━━━━━ 🎯WHAT I'M STRONGEST AT 🔍 SEO and AEO Strategy I rank my own products, so this isn't theory. FPL Oracle pulls 300K+ monthly impressions and ranks page one for competitive FPL terms. BackPage FC gets referenced across Google News and pulled 10K+ clicks last month. Both get cited by ChatGPT, Claude and Perplexity when people ask for tools in their category, which is answer-engine optimisation rather than traditional search. Technical SEO, schema markup, content architecture, backlink strategy, and structuring a site so AI models can actually parse and cite it. 🧠 AI agents and LLM systems LangGraph, LangChain, MCP servers, Claude, GPT, Gemini. Multi-step agent workflows, tool calling, structured outputs, evaluation harnesses. 📚 RAG Hybrid retrieval, reranking, confidence thresholds, grounded answers, sub-200ms retrieval. Whether a RAG system works or confidently makes things up comes down to architecture, not prompting. 🎙️ Voice AI VAPI, Retell, LiveKit, Twilio, Deepgram, ElevenLabs. I've built on managed platforms and rebuilt call infrastructure from scratch, so I know where each approach breaks. ⚡ Full-stack SaaS Next.js, React, Node.js, NestJS, Python, FastAPI, PostgreSQL, MongoDB, Redis, Supabase. Multi-tenant architecture, Stripe billing, auth. 🛠️ AI-native development Claude Code is my daily environment. Every project gets a CLAUDE.md with architecture standards and review rules so the codebase holds its quality as it grows. ━━━━━━━━━━━━━━━━━━━━ ⏱️ HOW I WORK I reply within an hour and scope before I start. I ship weekly. I'll tell you honestly when a timeline or approach is wrong. Docs and post-launch support are included. I take on 2 to 3 projects at a time. 🎓 MSc Artificial Intelligence, University of Surrey. Former Research ML Engineer at Databricks. Founding AI Engineer at Lightwork AI. Open source contributor to TensorFlow, PyTorch and Ivy. 📩 Send me your project details, and I'll come back with initial thoughts and a rough scope within the hour.
