Broken Replit app?
Let's fix it.
Replit development services help people who built an app on Replit — often with the Replit AI agent — turn it into a secure, reliable production product. I fix bugs, add proper databases, authentication and payments, and prepare the app for real users.
Already built something with Replit? I help startups and businesses build, fix, extend and productionize Replit applications — so the prototype that proved your idea can safely serve real customers.

Technical approach
- →Start with a code and security audit, then a prioritised fix list.
- →Move secrets to the server and add database access rules.
- →Add tests around the flows that make you money.
- →Keep you able to keep building in Replit after I hand over.
Frequently asked questions
Do I have to leave Replit?
No. Many apps run fine on Replit Deployments. I'll only suggest moving if your traffic or requirements call for it.
Can you fix code written by the Replit AI agent?
Yes — that's most of this work. I clean up the structure so both you and the agent can keep building safely.
Do you work with US companies?
Yes. I work remotely with startups and businesses across the United States and internationally, with overlapping working hours for calls and async updates in between.
