Po-Han H.
App Rescue Developer | Fix & Ship Half-Built Apps (Lovable, Flutter)
Your app was built with Lovable, Bolt, Base44 or another AI tool, and now it's stuck: a build that won't compile, broken auth, a payment flow that fails, or a release that keeps getting rejected. I take over the existing codebase, reproduce the problem, and fix it before touching anything else. If you're about to submit to the App Store, I also do a pre-submission audit: a written report within 48 hours listing every guideline risk I find (demo account, account deletion, in-app purchase restore, privacy labels) and the exact fix for each. My own Flutter app, Fooda, had sat unmaintained: 38,807 lines, 899 analyzer issues, Android wouldn't build. Two days later it was building clean and in TestFlight. I've added AI features to a Base44 CRM (React + Claude API) over 3 milestones. Published on the App Store: CamMenu, Fooda, GridDay, NearSafe (Taiwan only). Most recent client work: release testing and code review of an AI-built education platform, with step-by-step fix guides their own AI could follow. Five milestones, all approved, 5.0 review. Send me the repo link or a screen recording of what breaks, and I'll tell you in writing what's involved. HOW I WORK Fixed price per milestone, agreed before I start. Every milestone ends with something you can install or click through, not a screenshot. For client projects, the code, the servers and the store accounts are yours. I'm in Taiwan (UTC+8). I'm online when your workday starts, and you'll have progress waiting the next morning. I work best in writing, and I'm happy to get on a call when it actually helps. Not a fit: WordPress, Shopify themes, or pixel-perfect Figma-to-code work. Po-Han
