AI app repair / A real engineer in your corner
Built with Lovable, Bolt, Replit, Cursor or Claude Code? When the demo looks right but the app keeps breaking, I help find the cause, fix the blockers and get it ready for real users.
A few of the teams I've worked with
01 / Sound familiar?
You have already put time into this. The next step is to understand what is failing, keep what works, and fix what stands in the way.
Every new prompt changes something, but the original problem keeps coming back. I trace the cause in the code and check that the repair holds up.
The screens look finished, but accounts, saved data or connected APIs fail. I check the full journey, including what happens behind the interface.
A failed build or a blank live page can block the whole launch. I investigate the deployment, configuration and live errors to find what is different.
Before inviting customers, you want to know what could break. An agreed audit checks critical flows, data access and launch blockers, with priorities you can understand.
You do not need the technical explanation.
Start with “when I click this, that happens.”

The starting point is your app and its current stack. We agree on the important fixes before making changes.
Reproduce errors, trace their cause, and repair the underlying logic. Focus on the journeys users need, not another round of prompts that hides the symptom.
Review exposed secrets, login flows, session handling and server-side authorization. Check that one user cannot read or change another user’s records.
Replace missing or unreliable server behavior, validate incoming data, and handle external API failures with useful error messages.
Review schema, access policies and queries. Plan migrations and backups so a fix does not put existing customer data at risk.
Investigate slow pages, oversized assets, repeated API calls and expensive queries. Measure the affected workflow before and after targeted changes.
Fix build and environment configuration, verify key user journeys, and set up logging, deployment steps and rollback instructions appropriate to your app.

Access to your source code and connected services determines what can be repaired.
04 / A clear way forward
Start with a free conversation. A deeper code audit and implementation are paid work, scoped and agreed separately.
Walk through the problem and your goals in 20 minutes. We decide whether there is a useful next step together.
Review the code and reproduce failures. Get a readable list of issues, priorities and repair options.
Agree on deliverables, price and milestones. Keep useful work and review the changes as they happen.
Test the agreed user journeys, support deployment and document setup and remaining issues in your project.
Your code and accounts stay yours. Repair comes first; if replacing a module makes more sense, I explain why and agree on it with you. Costs and timelines follow the actual scope.
Your product. The right tools.

Chirag Gupta
Full-stack + AI Engineer
Based in India. Working worldwide.
I’m Chirag, a full-stack and AI engineer with 6+ years of experience. I help founders and businesses launch SaaS products, add AI to existing software, and get stalled prototypes working reliably.
I look beyond the feature list to how your product will actually be used. That means choosing AI where it adds value, simplifying complex workflows, and testing the details your customers will rely on.
05 / Before you book
Still unsure whether your app is a fit? That is a useful thing to discuss on the introductory call.
I can assess apps built with Lovable, Bolt, Replit, Cursor and Claude Code. What can be repaired depends on access to the source code, connected services and project accounts. Start by showing me the app and what breaks; I will explain whether an audit and focused repairs make sense.
Yes. You can explain the problem by showing the screen or describing what you expected to happen. I translate the technical findings into a clear issue list, priorities and options so you can make decisions without reading code.
The 20-minute introductory call is free and has no obligation. We discuss what you built, where it gets stuck and what you want to launch. It is a scoping conversation, not a full code audit or a promise to fix the app during the call. If a deeper audit is needed, we agree on its scope and cost first.
The cost depends on the condition of the code and the fixes you choose. An audit establishes what is broken, what is risky and what can be retained. I then estimate a prioritized repair scope; substantial replacement work is discussed and priced separately.
An isolated bug and an incomplete backend require different amounts of work. I can estimate the timeline after reproducing the problems and reviewing dependencies. Critical blockers come first, with milestones agreed before repair work starts.
I assess repair first. Replacing a module is justified only when the audit shows a concrete architectural, security or maintenance problem. We review the tradeoffs together and agree on scope before a partial or full rebuild.
Yes. Your repository, hosting and project accounts remain under your control. Changes and handover documentation go into your project. Existing third-party code, platform terms and dependency licenses still apply.
Continued maintenance can be agreed separately, including bug fixes, dependency updates and deployment support. The handover also records remaining issues so you or another developer can continue without relying on an undocumented setup.
Start with the app URL, a description of what breaks and the platform used to build it. For the audit, I need appropriate access to the repository and relevant configuration. Do not send secrets or customer data in a public message; we agree on a suitable access method.
06 / Your next step
You do not need to diagnose it first. Show me the app, tell me what should happen, and we will discuss a sensible path forward.
