Lovable & Base44 Developer | Bug Fixes, Supabase & Deployment
Your Lovable or Base44 app works in preview, then a login, payment or deployment step stops it going live. I'm a Lovable and Base44 developer who gets AI-built apps over the line. I reproduce the problem, fix the agreed scope, test the repaired flow and hand it over with notes. On Upwork that has meant a Lovable app completed over 40 hours (5-star), a Base44 app with Supabase login set up (5-star) and Stripe subscription webhooks, alongside a 100% Job Success Score. I also built Bottleneck, a voice-therapy mobile app, working from the client's template. WHAT I HELP WITH • Login, signup, data-saving and API errors • Supabase authentication and access rules (RLS) • Stripe, PayPal and RevenueCat payment flows • Deployment, custom domains and environment settings • Mobile packaging for the App Store and Google Play, after a readiness review QUESTIONS FOUNDERS ASK Why does my app work in preview but fail when published? Often the live version uses different settings, redirect URLs, keys or data rules. I check those first, then confirm the cause by testing. Can you fix a login or payment error? Usually, once I can reproduce it. I tell you the likely cause and the first check, then agree a fixed scope and price before changing anything. Do you use AI tools? Yes. I use AI coding tools such as Claude Code to read your codebase and speed up checks, and I test every fix myself before handover. I never paste your keys or private data into a tool, and I'll follow your preference if you'd rather I didn't. Is my Supabase data safe? I review your access rules and where keys are used, and report what I find. A public key in the browser is normal; privileged keys must stay on the server. Will you rebuild my app? Only if the review shows that is the better route, and I explain why before any extra work. Can you put it on the App Store? Possibly. Apple can reject a web app that is only wrapped, so I review it first and quote after. Approval is Apple's decision. I WORK BEST WITH Founders and small teams with an AI-built app that is nearly finished, agencies using Lovable or Base44 for clients, and wellness or coaching apps. WHAT I DON'T DO WordPress, Shopify or Wix sites, games, crypto, large native apps from scratch, unlimited fixes, or guaranteed store approval. Your hosting, Supabase and store accounts stay in your name. NEXT STEP Send your app link, the steps that fail and what should happen instead. I'll reply with the first check I'd run and a price for it.
