I'm Senula.

Student & Linux person

A/L student from Sri Lanka who spends way too much time on Linux. Into IoT, robotics, networking, and cloud — basically anything where you get to understand how things actually work under the hood.

about

Hey, that's me.

I'm a student from Sri Lanka who's really into figuring out how things work — not just using them, but actually understanding what's going on underneath. Big FOSS person. Linux is my daily driver and I genuinely care about open software and knowing what's running on my machine.

Most of my time goes into Linux, IoT, robotics, networking, and cloud infrastructure. I like the layer where software meets hardware — embedded stuff, networked devices, systems that do real things. I'm also slowly picking up offensive security on the side, mostly because understanding how things break is the best way to understand them at all.

Outside of that, I'm learning manual photography — shooting landscapes and figuring out exposure the hard way rather than letting the camera do everything. Still very much a beginner, but that's kind of the fun part.

stack

Stuff I use.

<?php · server-side
PHP
Web backends, REST APIs, and server-side tooling. Gets the job done without ceremony.
#!/bin/bash · system
Bash
Automation, system administration, and scripting. The glue of every Unix environment.
>>> · scripting
Python
Network tooling, security scripts, data work, and rapid prototyping.
0x · embedded
C / Arduino
Microcontrollers, sensors, and hardware projects. Software that talks to silicon.

interests

Things I'm into.

01
Linux & FOSS
Daily driving Linux and passionate about open-source software. I like knowing what my system is actually doing — reading configs, not just clicking through GUIs.
02
IoT
Embedded systems, microcontrollers, and devices that interact with the physical world. There's something satisfying about software that does something you can actually see and touch.
03
Robotics
Where hardware, software, and logic all have to work together at once. I find the intersection of all three way more interesting than any one of them alone.
04
Networking
How packets move, how protocols are designed, how machines talk to each other. The lower layers are honestly more interesting than most things built on top of them.
05
Cloud & Infrastructure
How distributed systems scale, fail, and recover. The kind of stuff that's invisible when it works and catastrophic when it doesn't.
06
Security
Still learning, but getting into offensive security concepts — how vulnerabilities actually work. Turns out breaking things is a pretty good way to understand them.
