Fix & Launch Lovable, Base44 & AI-Built Apps | SaaS, Mobile, React
I take over web and mobile apps that work in a demo but aren't ready for real users: half-finished builds, buggy SaaS products, and apps built with Lovable, Base44, Bolt, Cursor or Claude Code. I work with AEX Soft's senior engineering team to find what's broken, fix it properly and get the product launched. What I help with: - AI-built app rescue - code review and fixes for these apps, including Supabase backends: authentication, data security, payments, performance and deployment - Stabilization and bug fixing - taking over an existing SaaS codebase, fixing what breaks and keeping it stable - Launch - environments, deployment and CI/CD on AWS, Azure, Vercel, Cloudflare, Fly io or Firebase - New builds and MVPs - when starting fresh beats patching: React, Next.js, Node.js and .NET - Mobile apps - iOS and Android apps in React Native, Expo or Flutter built from scratch or sharing a backend with your web product - Payments and integrations - Stripe, HubSpot, Twilio, Microsoft Dynamics 365 and other third-party APIs Recent rescue projects: - SaaS platform for coaches and athletes, built by another developer. We fixed production bugs, optimized the code and removed a lot of unused code, which made it faster with fewer bugs. We redesigned the UX/UI, so the flow is clearer and it no longer looks like an MVP, then deployed the stable version. - MVP built with Claude Code. We added Stripe integration, fixed bugs, built new features and switched off what wasn't working. Now adding integrations and a new UX/UI to turn it into a scalable platform ready for real users. Selected work: - RallyUp - web and mobile fundraising platform for nonprofits across the US and Europe, including campaigns by Tom Holland and Katy Perry. Our team built it from scratch and still runs its engineering: $1B+ processed on Stripe, 30+ integrations, an Inc. 5000 company - CMOS/ClearMechanic - Latin America's leading SMB SaaS platform for automotive repair, web and mobile, built from scratch and run by our team since 2010. 100,000+ active users, 23M repair orders, adopted by Jaguar Land Rover, BMW and General Motors, operating in 8 countries - Boostlingo - web and mobile interpretation platform our team built, with 17,000+ interpreters. HIPAA and SOC 2 Type II compliant, #839 on the 2024 Inc. 5000 - Independent Reserve - Australian crypto exchange, the first licensed in Singapore, 300,000+ users - A production app shipped on Base44 for an Australian company - Also built: Mmme (family photo-sharing app), Yammat (social network for musicians) and SysDEM (food manufacturing software) Stack: React, Next.js, TypeScript, Node.js, .NET/C#, Python, React Native, Flutter, Expo, PostgreSQL, Supabase, Firebase, AWS, Azure, Vercel, Cursor, Claude Code, Codex, Webflow Where we tend to be the right fit: - Founders with an AI-built app that has to be production-ready before real users arrive - Funded startups and growth-stage SaaS companies that need senior engineering depth - Teams looking to ship a SaaS MVP fast without sacrificing architecture quality - Founders who need a long-term product partner, not freelance execution Just invite me to your job posting (click the "Invite to job" button at the top right of my profile) or send a message and let's talk!
