Bolt, Lovable, Cursor, and Claude Code get you 70% of the way there. The last 30% is where I live. I finish and harden AI-built apps, and I build production AI from scratch. If your app demos well but falls apart once live users hit it, saves that don't stick, a data model that buckles at scale, security holes you can't see, that is what I fix. I also build the AI itself: phone and voice agents that book appointments, agentic workflows, and full Supabase and Stripe backends. I know where these tools break because I clean it up for a living. One Lovable app owner described it as "fix one thing and five break." That traces straight to the generated backend, the data model and the save logic, not the features. Solidify that and the cascading bugs stop. Recent work: • AI phone receptionist for a service business. It answers and texts customers in the owner's voice, books appointments, and writes them straight into their Jobber CRM: client, job, and visit created automatically, nothing re-keyed in the morning. Built on Twilio, a voice agent, and a knowledge base of the owner's own playbook. • Took a Lovable-built MVP to production: a creator marketplace that generated 150M TikTok views and paid out $15,000 to 200+ creators. Stripe Connect plus PayPal payouts, TikTok API, multi-tenant row-level security. Client: "Andrew got my MVP over the line and helped bring my vision to life." • Overhauled a production voice agent for a hospitality venue handling live booking calls, then built one source of truth so non-technical staff edit a single page and both the text bot and the voice agent update from it. • Audited a Supabase app and found 14 significant bugs, including booking records any logged-in user could read and missing security rules. Every finding came with the specific fix and why it matters. • Stabilized a Lovable carousel app's edit and save flow so edits stick and it holds well past its first users. How I work: • Fixed price per milestone. You know the cost up front, there is no open meter, and you only move to the next piece once the current one is done and working. • I use Claude Code and Cursor to ship 2-3x faster, and I verify everything the AI touches. • Straight about tradeoffs and limits up front, especially on security work. • I explain technical decisions in plain English. Most of my clients are not developers. Stack: Supabase (Postgres, RLS, Auth, Edge Functions, Vector/RAG), Stripe (Connect, Subscriptions, webhooks), React, Next.js, React Native, TypeScript, Node.js, voice agents (ElevenLabs, Retell), Twilio, OpenAI and Claude APIs, n8n, Vercel. Background: 10 years full-stack across health tech, edtech, and fintech. Taught two web development bootcamps. Top Rated, 100% Job Success, $60K+ earned. If you built something with AI and it is almost there, send me a message. I will tell you straight what it needs, and what it does not.
