Here is how I solved it:

⚡ Problem: OCC locks documents; manual merging wastes critical outage minutes.
⚡ Solution: CRDTs (Conflict-Free Replicated Data Types) via Yjs + Hocuspocus. Every keystroke converges automatically with zero merge conflicts.
Code quality > quick hacks🚀

What happens when 10 engineers edit an incident doc during a P0 outage?
In traditional CRUD, the last "Save" overwrites everyone else's findings (or throws a 409 Conflict).

So,I built SignalDesk — a real-time incident intelligence & collaboration backend.

Just attended #GitHubUniverse 2026 and wow. The way developer workflows are changing is unreal. New architecture, brand new functionality, & a new era for how we build software. Excited to dive in. 🚀
As a developer seeing where dev tools are heading made me even more excited. 💻

Excited to share that I scored 98.36 percentile in Naukri Campus Young Turks 2026, presented by HCLTech🏆

Competing against students across India makes this achievement even more rewarding.
Grateful to Naukri Campus and its industry partners for recognizing this.

@dogramaci These points make workflows easier :

1.Version prompts like code.

2. Separate structure from content.

3. Build an eval set early.

4. Pin model versions and re-run evals before upgrading.

5.Keep prompts short and prune patch rules.

6.Validate outputs in code.

If you get a new backend requirement, how do you design its MongoDB schema?

To answer this, I built CampusStore — a campus student marketplace designed database-first, not feature-first. 🧵👇

I’m turning my backend engineering journey into a living open-source roadmap that grows with every new concept I build.
Instead of just reading theory, I'm building real architectures, documenting every concepts and update daily🧑‍💻

Few days into DSA.

Slowly realizing it’s not just about solving questions—it’s about learning how to think about problems logically.
Now, connections of logic are starting to click.

Still learning. Still figuring things out. 💻🧠

It has been a great learning journey, and I’m grateful for the experience and knowledge I gained.

Looking forward to more opportunities to learn, build, and grow in the tech industry! 🚀

@NVIDIAGeForce Training deep neural networks on local hardware shouldn't mean endless waiting.
A GeForce RTX 50 Series laptop gives me the desktop-grade Tensor Cores needed to optimize custom LLMs and accelerate training loops on the go. Time to build faster!
