🚀 You're building an AI-powered product. You need someone who ships the whole thing — not just the AI layer. I'm a Senior Full Stack Engineer with 8+ years specialising in Full stack development & AI-integrated SaaS platforms. I've architected multi-tenant systems, wired LLMs into production backends, and shipped complete products — auth, database, billing, and AI pipeline — from scratch. Most "AI developers" can call an API. What they can't do is design the schema, enforce data isolation at the Postgres level, wire Stripe for usage-based billing, and deploy it all on a zero-downtime infrastructure. That's where I'm different. 🔹 AI Integration & LLM Engineering I build production-grade AI features — RAG pipelines, streaming chat interfaces, document intelligence, OpenAI and Anthropic API integration, vector search with pgvector and Pinecone. I focus on making AI reliable, cost-efficient, and actually useful in a real product. 🔹 Multi-Tenant SaaS Architecture Designed and shipped multi-tenant platforms with workspace-level data isolation, RLS policies enforced at the Postgres level, and Supabase backends that scale cleanly. I've built the kind of schema that doesn't fall apart at 10,000 users. 🔹 Full Stack Product Engineering Next.js, TypeScript, Node.js, NestJS, PostgreSQL, Supabase — I own the entire stack. Not just the frontend, not just the API. The whole product, built to hand off cleanly to your team. 🔹 Stripe & Billing Systems Usage-based billing, seat pricing, metered subscriptions, webhook-driven lifecycle management — wired directly to Supabase Edge Functions for reliability and auditability. Recent work: ✅ TryMyGuns — Lead Architect. Multi-role marketplace with full buyer/seller/admin data isolation, built and deployed in 4 weeks. If you're building an AI SaaS product and need an engineer who takes full ownership — let's talk.
