Jake W.
Full Stack Engineer | AI MVP to Production, LLM Features & App Launch
You built it with AI. It demos fine. Real users and an App Store reviewer are a different test. I take over Lovable, Replit, and Claude Code apps, add the LLM features they're missing, and ship them live. 10+ finished, Top Rated. The demo works because you're the only person using it. Then someone else logs in and sees another user's rows, because row level security was never switched on. A write that reported success never landed. None of that shows in a demo. It shows in week 2. So the launch slips. You can't put customers on a database you don't trust, or submit a build nobody has signed. The app isn't broken. It's unfinished, and finishing is a different job from building. Somebody has probably told you this needs a rebuild. It almost never does. Rebuilding is what a developer says when they don't want to own code they didn't write, and that's my day job. 8+ years of full stack work. A Replit MVP I took over now runs a company with 300+ employees, I've kept a customized CRM alive since 2020, and the MMORPG I work in isn't my code either. 🏆 "Great communication, easy to work with, quality work!" - Backup and restore, broken inside a React tool ChatGPT wrote. 5 stars. 🏆 "Fantastic work. I'll definitely being hiring Jake again." - Data capture and a Mailchimp integration across HTML calculator sites. 5 stars. 🏆 "Awesome job as always!" - A second contract from the same client. Multi market tabs and a data save feature in their Vercel app. 5 stars. 𝗜𝗡𝗗𝗨𝗦𝗧𝗥𝗜𝗘𝗦: Solo Founders • Product Studios • Marketing Agencies • Consumer Mobile • Gaming • Restaurants • Ecommerce Ops • SaaS • Marketplaces • Internal Ops 𝗪𝗛𝗔𝗧 𝗜 𝗧𝗔𝗞𝗘 𝗢𝗩𝗘𝗥 𝗔𝗡𝗗 𝗙𝗜𝗡𝗜𝗦𝗛 ✔️ AI Built Apps, All The Way To Production 10+ finished, from Replit, Claude Code, Bolt and Base44 prototypes to production SaaS. A takeover, not a rewrite. API keys come out of the browser bundle, row level security gets tested table by table, slow queries rewritten. ✔️ LLM Features Inside A Product That Already Works Chat over your own documents. An AI agent that automates one workflow. A Claude or OpenAI call that fails safely when the model is slow. The AI chatbot I built for a marketing agency runs inside their own system, same codebase as their client records, campaigns, and payments. Not a widget on a website. Anthropic certified me in Claude Code. ✔️ Next.js & Supabase: CRMs, Field Service Management, Internal Tools 5+ running inside client companies today. One dashboard instead of five subscriptions, plus the automation between them. Xero, QuickBooks, HubSpot, and Shopify integrations built or replaced, old and new side by side until records reconcile. ✔️ Mobile App Releases: App Store And Google Play React Native and Expo mobile apps for iOS and Android, built and submitted. TestFlight to your testers, App Store Connect configured, signing sorted, the Play data safety form done right. 3 of my own apps cleared full Apple review, so I know why a wrapped web app fails Guideline 4.2. ✔️ A Founder MVP That Can Take Payment The smallest version a customer will pay for, live on the web or in both stores. The rest waits. 𝗦𝗛𝗜𝗣𝗣𝗘𝗗, 𝗡𝗢𝗧 𝗗𝗘𝗠𝗢𝗘𝗗 🏆 A Replit MVP That Became The System A Company Runs On Took over the codebase, migrated it to AWS, stayed 7 months. → Result: it runs today as the internal tool for a company with 300+ employees. 🏆 A Marketing Agency's Internal System On Next.js And Supabase Client management, campaigns, the payments tied to them, and an AI chatbot for the agency's own use. → Result: the backbone of their company rebrand. They went on to raise 3M+ CAD. 🏆 iBite, My Studio's Location Based Food App A live 3D city map with AR menu previews, on Firebase and Stripe. → Result: through full Apple review, live on iPhone, iPad, Mac, and Apple Vision at 5.0. 𝗪𝗛𝗬 𝗛𝗔𝗡𝗗𝗜𝗡𝗚 𝗜𝗧 𝗢𝗩𝗘𝗥 𝗚𝗢𝗘𝗦 𝗕𝗘𝗧𝗧𝗘𝗥 💡 I'll talk you out of work you don't need. If your app is fine where it's hosted, you hear that first. 🎯 iBite Technologies is my studio, so a rejected build costs me, not a client. ⚡ A scope written down before anyone opens an editor, and a reply inside 4 hours, US Pacific. 𝗪𝗛𝗔𝗧 𝗟𝗔𝗡𝗗𝗦 𝗜𝗡 𝗬𝗢𝗨𝗥 𝗔𝗖𝗖𝗢𝗨𝗡𝗧 ✅ Your app in your own App Store Connect and Google Play Console, under your developer account, never mine. ✅ Real logging on, so you see swallowed errors and webhooks that quietly stopped firing. 𝗧𝗛𝗘 𝗦𝗧𝗔𝗖𝗞 𝗜 𝗜𝗡𝗛𝗘𝗥𝗜𝗧 𝗔𝗡𝗗 𝗕𝗨𝗜𝗟𝗗 𝗜𝗡 → Build: React, Next.js, React Native, Expo, Node.js, TypeScript, Laravel, Python → Ship: AWS, Vercel, Supabase, PostgreSQL, Firebase, Stripe, App Store Connect, Google Play Console → AI: Claude Code, OpenAI API, Cursor, Lovable, Replit, Base44, Bolt.new, v0 📩 START WITH A LINK Send the app, the repo, or two sentences about the idea. You'll get back the first 3 things between it and a paying customer.
