I build practical security tools and automation systems that people can actually use
Most of my work starts with a simple question: what can we remove so the system becomes faster, safer, and easier to run? I like building things that hold up outside a demo.

About Me
I spend a lot of time inside Linux terminals, network maps, and half-finished notebooks. I like figuring out why systems break, then rebuilding them in a way that feels cleaner and easier to maintain.
My projects usually mix software with real constraints: unstable inputs, noisy logs, devices that are not always cooperative, and timelines that move fast. That is the part I enjoy most.
I have worked with Kali Linux, networking fundamentals, automation scripts, and Arduino-based prototypes. Lately I have been going deeper into ethical security testing and operational tooling.
I am still learning every week, and that is intentional. I would rather ship honest, useful work than polish an idea forever.

How I Build
Modular First
If a system cannot be split and reused, it becomes expensive fast.
Security by Default
I prefer safe defaults over “fix it later” security patches.
Practical Scope
Useful and shipped beats perfect and unfinished.
Fast Feedback Loops
Small releases, fast tests, and honest postmortems.
