Most AI SaaS products look great in the demo. They fall apart the moment a real user hits an edge case, a second tenant logs in, or the LLM returns something unexpected.
I am an AI Product Engineering Lead and Full Stack Developer with 10 years of production experience building software products, and the last two years focused specifically on LLM apps, AI Agents, and AI SaaS MVPs that founders can demo, sell, and raise funding with. My engineering background includes Aricoma Group, a $460M enterprise technology company, and I now lead AI product development at Moonstruck where every build is production-grade from day one.
One client, after I built his AI-powered internal tool for Search Console analysis, said this: "I have spent over $30,000 on Upwork across a wide range of projects, and this has been one of the best experiences I have had on the platform." That is the bar I work to on every project.
WHAT I HAVE SHIPPED
These are not personal projects. These are production AI apps and internal tools running right now for real businesses.
→ An AI Competitive Intelligence Platform for an iGaming operator that replaced 15 hours of weekly manual market monitoring with a 2-minute automated brief across 40+ operator sites, built on Next.js and Supabase
→ A multi-tenant Uniform Procurement Platform serving 10+ hotel groups across 30+ properties, cutting order-handling time by 70% and saving an estimated $20K a year in admin costs
→ A full SaaS platform for Traken that became the core of the startup's product and helped secure $600K in competitive grant funding including EU Innovation Fund and EIT Climate-KIC backing
→ PulseDex, a real-time crypto trading platform built on Node.js, React and PostgreSQL, running live for around 1,000 concurrent traders
→ A Barbershop Booking Platform handling around 1,800 bookings a month across 10+ staff, eliminating 8 hours of manual scheduling through intelligent automation
WHAT I BUILD FOR YOU
→ AI-powered SaaS and MVPs with LLM features built in, OpenAI API and Claude integration, multi-tenant architecture, Stripe billing, and row-level security, architected to scale from day one not patched later
→ AI agents and RAG systems built around your actual business logic, not wrapper demos that break under real usage, deployed on OpenAI API, Claude, and custom pipelines
→ Internal tools and AI-powered dashboards that replace manual workflows with intelligent automation, the kind that saves your team hours every single week
→ Full stack web platforms built on Next.js, Node.js, React, Python, Supabase, and PostgreSQL with auth, admin panels, and production-ready API integration from day one
HOW IT WORKS
Every project starts with a scoping call and a shared features document. I propose fixed-price milestones so there are no hourly surprises. I design the system and build a clickable prototype before writing any production code. Once approved, phased builds with daily updates until launch. After launch, ongoing support is available and I will give you a straight second opinion on scope and go-to-market whenever you want one.
