Hi, I'm DEV.BAK, a software developer.
I build web services across the backend and frontend. On this blog I write about what I've actually learned hands-on — the problems I ran into, how I dug into the root cause, and how I solved them.
Topics I mostly cover:
- Backend: API design, databases, distributed systems, observability
- Frontend: Next.js, React, web performance
- Developer tools & productivity: dev workflows and automation
Thanks for reading. If you have any questions or feedback, feel free to reach out via the email above.
