Project details
AI-generated code might look good at first, but under the hood, it often leads to costly bugs and unscalable architecture. Many people end up with server bills in the thousands due to poorly optimized code.
I'm here to fix that.
With years of experience in web development and software engineering, I specialize in auditing and optimizing AI-generated apps.
I can identify what features will scale, what won't work in the market, and why your code may be costing you more than it should.
I don't just fix bugs, make your code deployment-ready, and add the features you wanted but couldn't implement due to limitations in AI-generated logic or lack of engineering support.
If you've built something with AI tools like Lovable but are unsure if it's ready for production, send it my way. I'll review or audit it in 30-40 minutes and help you move forward with confidence.
Let's turn your idea into a product that actually works.

Chrome Extension Fixing and Implementing Blocking Trackers Feature
Great guy, worked extremely hard to bring my project idea to reality, couldnt recommend anyone better. I have had to hire numerous developers previously who constantly kept letting me down, but Umar was different anytime there was any issue I could rely on him to solve it. He even went as far as explaining the code in-depth so that I understood every single aspect. Dedicated, realiable and honest, expect these qualities if you hire Umar.
