About this service

Summary

I help founders and developers build or fix their Replit web and mobile apps fast, clean, and ready for launch.
Whether your project runs on React Native, Expo, or Vite, I’ll debug, optimize, and deliver production-ready builds for iOS, Android, and desktop. With years of experience in full-stack development and real deployment pipelines, I make sure your app actually works, not just runs.

FAQs

  • Can you fix an existing Replit project that’s not working or showing build errors?

    Absolutely. I specialize in debugging and fixing Replit-based web and mobile apps — including issues with React Native, Expo, and Vite builds. I can diagnose the root cause (code, environment, or dependency) and make it production-ready again.

  • Do you only work in Replit?

    No. I can also help migrate your Replit project to a local or GitHub-based environment if you plan to scale. But I can do everything directly inside Replit too, including build scripts, testing, and deployment setup.

  • Can you make my Replit app work on iOS and Android?

    Yeah absolutely I can configure your project with Expo or React Native to build on both iOS and Android, including preparing it for TestFlight and Google Play submission.

  • What if my app is half-built or has messy code?

    No problem. I’ve fixed and refactored plenty of unfinished Replit apps. I’ll clean up your code, structure it properly, and ensure it runs smoothly with clear documentation for future updates.

  • How long does a typical build or fix take?

    Simple fixes usually take 1–2 days, while full rebuilds or feature upgrades may take 3–7 days depending on complexity. I’ll always review your project first and give an exact timeline before we start.

  • Will you help me publish my app to the App Store or Google Play?

    Yes, if you’re using Expo or React Native, I can guide you through the submission process or handle the build configuration so you can easily publish from your account.

What's included

  • Complete Replit App Setup & Environment Configuration

    I’ll set up a fully working Replit environment for your web and mobile app, including all dependencies, environment variables, and build scripts. This ensures your app runs consistently across iOS, Android, and desktop versions. I’ll also configure Expo, React Native, or Vite (depending on your stack) for local and cloud builds.

  • Code Fixes, Debugging & Feature Implementation

    I’ll identify and fix critical bugs or errors preventing your app from running smoothly. This includes resolving build errors, runtime issues, and integration problems (e.g., API connections, database syncing, or authentication). Additionally, I can develop new features or screens as needed — with clean, modular, and maintainable code.

  • Responsive UI/UX Optimization

    I’ll optimize the app’s layout and interface to ensure a seamless user experience across web, tablet, and mobile devices. This includes fixing layout issues, improving navigation, enhancing component styling, and aligning with your brand guidelines.

  • Testing, Debug Mode & Deployment Readiness

    Before delivery, I’ll test the app thoroughly across platforms to ensure stability, speed, and compatibility. I’ll prepare your project for deployment on TestFlight (iOS), Google Play (Android), or web hosting (Vercel/Netlify/Replit hosting). You’ll receive a working build and clear instructions for future updates.

  • Documentation & Developer Handover

    I’ll provide a concise developer handover document covering environment setup, dependencies, and build steps. This helps you or your future developers easily continue updates or feature development without confusion.

Recommendations

Marc communicates excellent and is very professional and knowledgeable. I highly recommend him for your projects!!

I enjoyed working with Marc. He's an easy going guy that actually knows his stuff. I was a bit worried when we hit some snafus, but he got the job done. Note: Allow more time than you think because we hit delays with Replit and Supabase

Professional negotiations and high quality project management and work product. Was very flexible to adjust deliverables when asked on many of the different projects I’ve outsourced to Marc.
