Samuel O.
AI MVP & Mobile App Developer | Base44, Lovable, React | Fix & Launch
Built an app with Base44, Lovable, Replit or React but struggling to get it working properly or published? I help founders and small businesses fix, connect and launch AI built web and mobile apps. I start with what you already have, find what's blocking it, and agree a clear scope before any work begins. What I fix and build 📌 Broken login, signup, user permissions and navigation 📌 Failed API connections and Supabase or Firebase database issues 📌 Unfinished features in Base44, Lovable and Replit apps 📌React and React Native features, and Capacitor mobile builds 📌 RevenueCat subscriptions and in app purchases 📌 App Store and Google Play submission support 📌 n8n workflows, webhooks and error alerts Work on Upwork includes Base44 app debugging, CRM feature changes, n8n lead workflows, and iOS integration with OpenAI and RevenueCat. How we work 1. You share the app, the platform and what's wrong. 2. We agree the scope, the access needed and how we'll test it. 3. I fix or build the agreed work and send updates as it moves. 4. You get the tested result and a clear handoff. Questions clients ask Can you fix an app another tool or developer started? ✅Yes. That's most of my work. I review the app first and tell you what can be fixed within your budget. Can you get my app approved by Apple or Google? ✅I can prepare the build, fix technical issues and support the submission through your developer accounts. The final decision belongs to Apple or Google. Will you change things I didn't ask for? ✅No. We agree the scope first, and I check with you before anything else changes. For live apps, we plan how to protect your data before release. What do you need from me to start? ✅Access to the project, any paid plans the platform requires, and a list of what should work when we finish. Send me your app and what you need fixed, connected or published, and I will tell you what I'd check first.
