I help founders ship SaaS and AI products people can actually pay for: secure login, a production database, Stripe payments and AI features built in from day one. Already have a Lovable, Replit or Bolt prototype? I take it to production. Top Rated · clients in the US, UK and Europe Your prototype works in the demo. Real users, real data and real payments need the parts a demo skips: access rules enforced on the server, a production database with backups, Stripe webhooks and failed cards handled, no exposed API keys, and hosting you own. That gap is what I close. RECENT WORK - OpsVanta (IST Networks, part of Teleperformance) – an internal ERP I built solo in Lovable + Claude Code. 120 database tables, all with row-level security, 7 user roles, AI insights built into daily workflows. Almost the whole company runs on it. - Boivin Coaching – the full business platform for Belgium's #1 all-time poker player, built in Replit on Supabase: sales site, application funnel, Stripe subscriptions, role-based members area, referrals and admin. 318 users and growing, ongoing since March 2026. - StoreFilter – an AI analyst for Shopify stores on 2.5 million records (Next.js, Supabase, pgvector, GPT-4). - PayRight (UK) – AI that checks every supplier invoice against the contract, with a human in the loop. - 7Centre – founding engineer on a multi-tenant ESG SaaS and a Flutter scan-to-data app. WHAT I CAN DO FOR YOU - App rescue – a written audit of what blocks launch, then fixes to auth, Supabase RLS, payments, security and deployment. Usually no rebuild needed. - MVP / SaaS builds – login, database, payments, admin and deployment, on accounts in your name. - AI features – RAG chatbots over your documents, AI agents, OpenAI / Claude / Gemini integrations. - Internal tools – replace the spreadsheet your team fights with every week. HOW I WORK - Written scope and fixed price before any code - Claude Code and Codex do the typing; I plan the architecture and review every change before it ships - Preview links at every milestone - You own the code and the hosting - Daily overlap with US Eastern and UK working hours Stack: React, Next.js, TypeScript, Node.js, Supabase / PostgreSQL, Stripe, Vercel, Cursor and Claude Code. Send me your app link (or idea) and what's blocking you. Within 24 hours you'll get what I'd fix or build first, and a fixed price.
