Hi, I’m Sumit Chaurasiya 👋
I go by YoYo178 online.
I don’t move forward until I understand what’s happening.
I’m a backend-focused software engineer who builds real systems and learns them the hard way — by reasoning, verifying, and maintaining them after they break.
I use AI to think with, not to skip thinking 🤝
If something doesn’t make sense, I stop, trace it, cross-check it
(docs, articles, Stack Overflow), and only then ship.
- Production-grade backend systems (Express.js, NestJS, security best practices)
- Real-time capabilities (Socket.IO / WebSockets)
- Auth flows I can explain end-to-end (JWT, sessions, OAuth2)
- Boring infrastructure that stays up (Nginx, EC2, S3, CI/CD)
I value clarity, correctness, and maintainability over cleverness.
- Talketeer — live chat app, real users, real infra
- Chess API — full game logic + REST API from scratch
- Notes App — media support + files management using Multer
- Open-source contributor & project maintainer
If it’s on my GitHub, I can explain why it exists and how it works.
I’m still a student 🎓
That just means I’m early — not shallow.
Actively looking for backend or backend-heavy full-stack roles where I can build, reason, and grow alongside strong engineers.
