I will fix bugs and add features to your web app
Karndevsinh J
About this gig
Your web app has a bug you cannot track down, or a feature you need and nobody to build it. I fix it, test it and explain what I changed.
What I work on:
- Bugs, broken forms, login and payment issues, slow pages
- New features: filters, search, CSV or PDF export, user roles, email notifications
- Connecting your app to another service through its API
- Cleaning up messy code so the next change is easier
How I work: you send the code access and a short description of the problem. I confirm what I understood before I start, keep you updated, and send a plain-language note of every change.
Works with JavaScript, HTML and CSS, Node.js, Python, PHP and SQL databases. If your stack is different, message me before ordering.

I help small businesses and startups fix, build and organise the software they run on. Fifteen years in technical and operations management means I ask about the business problem first, then build the smallest thing that solves it. You get regular updates, clear documentation and a handover you can use without me.
FAQ
Do you sign NDA?
Yes, if you need one.
Will you keep my code private?
Yes, I will use it only for your order.
What if you cannot fix it ?
I tell you early. If I cannot solve it, I will say so and you can cancel the order.
