Building software, understanding systems,
and documenting everything I learn.

I'm a recent Computer Science graduate exploring software engineering one project at a time. This blog is my engineering journal—covering Linux, Python, Go, JavaScript, backend development, Data Structures & Algorithms, system design, and the lessons learned while building real software.

Things I've learned the hard way.

Every article comes from building something, debugging something, or finally understanding something that confused me far longer than it should have.

System design

Architecture calls, trade-offs, and the diagrams behind them.

DSA

LeetCode traces, patterns, and the bug in my mental model.

Error fixes

The exact stack trace, the exact fix, no fluff.

Frameworks

React, Astro, Kotlin — deep dives as I actually learn them.
