I Got Tired of Having Different Profile Pictures Everywhere, So I Built ProfileSync

A few weeks ago, I noticed something embarrassing.

My GitHub profile picture was updated.

My LinkedIn profile picture wasn't.

My coding platform accounts were using even older photos.

Without realizing it, I had created multiple versions of myself across the internet.

That got me thinking: why is there no simple way to check whether all my profile photos are actually in sync?

So I spent some time building ProfileSync.

What is ProfileSync?

ProfileSync is a web application that lets you upload a master profile photo and compare it against the profile pictures used across different platforms.

Instead of opening five different websites and checking manually, you can see everything from a single dashboard.

Currently, it supports:

• GitHub
• LinkedIn
• LeetCode
• CodeChef
• Codeforces

How It Works

The idea is simple.

1. Upload your preferred profile photo.
2. Enter your usernames.
3. ProfileSync fetches profile images from supported platforms.
4. The images are compared against your uploaded photo.
5. Each platform is marked as:

• Synced ✅
• Out of Sync ⚠️
• Empty 📭
• Unverified ❓

The goal isn't to manage profiles directly. It's to quickly identify where your online identity isn't consistent.

Challenges I Faced

One thing I learned while building this project is that fetching profile pictures isn't as straightforward as it sounds.

Every platform works differently.

Some provide APIs.

Some require alternative methods.

Some rate-limit requests.

Some return fallback images that can accidentally look like real profile pictures.

To handle this, I added caching, fallback detection, and additional validation to avoid false results.

Another interesting challenge was image comparison. I didn't need AI or heavy computer vision libraries. A lightweight pixel-comparison approach turned out to be more than enough for this use case.

Built With

• Next.js 16
• TypeScript
• Tailwind CSS
• Framer Motion

What I Learned

This project helped me improve my understanding of:

• API integration
• Image processing
• Authentication flows
• State management
• Full-stack application architecture

More importantly, it reminded me that many useful projects start with a very small personal annoyance.

What's Next?

I'm considering adding:

• More social platforms
• One-click profile updates
• Sync history
• Better analytics
