About this gig

Is your React or Node.js app broken and you 

have no idea why?


Bugs do not just slow your app down - they 

cost you time, money, and users. The longer 

they stay, the worse it gets.


I am Saykot, a full-stack developer with 

hands-on experience in React, Next.js, and 

Node.js. I do not just patch the symptom - 

I find the root cause and fix it properly.


Here is what you get when you work with me:


- The exact bug identified and fixed cleanly

- Code that is tested before I deliver

- A clear explanation of what caused the issue

- No messy workarounds, no temporary fixes


Technologies I fix:


- React.js and Next.js frontend issues

- Node.js and Express.js backend errors

- MongoDB and MySQL database problems

- REST API failures and integration bugs


One thing I do differently - I ask you to 

message me before placing an order. I want 

to understand your problem first and make 

sure I can actually solve it. No wasted time 

for either of us.


If your app is broken, let us fix it the 

right way. Send me a message now.
