I've been a passionate coder for 6years now. I've built several fun projects throughout that time like space invaders style game, an online exam website, social media app, messaging app etc. For those projects, I used various technologies ranging from simple html, css,js to complex frameworks and libraries like react, nextjs, mongodb. Now, I'm looking to offer my services on fiverr.

FAQ
What counts as a "bug" for the Basic ($10) package?
The Basic package is for 1 simple, isolated issue that can be fixed with a minor change in the MERN stack (e.g., a typo, a CSS issue, a small logical error, a minor React state bug, etc.). If it requires more than 1 hour of investigation, you'll need the Standard or Premium package.
What kind of project code do you work with?
I specialize in projects built with the MERN stack: MongoDB, Express.js, React (including Next.js), and Node.js. I can handle both frontend (React) and backend (Node.js) issues.
Can you fix API or database connectivity issues?
Yes. I am proficient in resolving API issues between React / Next.js and the Node.js backend, including CORS errors and basic MongoDB connection or query problems. q What if you can't fix the bug in time?
What if you can't fix the bug in time?
If the bug requires more time than covered by your package (e.g., Basic is 1 hour), I will immediately inform you. We can then either agree on a Premium package upgrade or you can use your included revision to clarify the issue before a final delivery.
