 const UserProfile  =  ()  =>  { 

  const  [userData,  setUserData]  =  useState(null); 

  const  [loading,  setLoading]  =  useState(true); 
// ISSUE: Memory leak causing app crashes
useEffect(() => {
fetchUserData();
}, []);
// FIXED: Added cleanup to prevent memory leaks
useEffect(() => {
let isMounted = true;
fetchUserData(isMounted);

What does it mean to fix an app?

It is pretty much what it says on the tin - sometimes apps get built, they go wrong, or essential changes are needed, you can't get the results from the developers you originally hired, and so you need a fresh start with someone new that can help.

How can we help?

We will start by listening and then asking questions. We must understand where the issues lie, what you are seeking to achieve, and what has been done so far. From there, a deeper dive into the technology in place will be needed and following that we will create a list of recommendations.

Each project is unique, and so the fix will be unique, it could be as simple as guiding you to make some simple changes yourself or it may require parts of your software to be re-written by us.
