Hello! I'm Sajid. I'm a web developer since the year 2022. Let me tell you a bit about my workflow. So, when I create sites, my main priority is ensuring that the user no matter who and where they are gets the best experience. That means to create a good balance between load times and features while also being accessible under poor network conditions. And I do all that by using specialized frameworks for each case. If that sounds like what you want, please feel free to reach out. I can't wait to work with you.

Perguntas frequentes
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.
