Happening Design

- Figuring out, what to do, and how to do it.
Hey, I'm
Chirantan
Curiosity and a bit of FOMO keep me exploring one layer deeper.
Currently working as a Software Engineer.
Interested in backend engineering, distributed systems, cloud infrastructure, and databases.
I enjoy breaking down complex systems, building side projects, and sharing what I learn along the way.
