Journey

My path in technology.

2009

Came to this world

tap

My mom and dad had a shebang and thus here i am.

2014

The First Victim

tap

Took apart an RC car in kindergarten. The battery wire broke, so I taped it back together since I didn't have a soldering iron. It worked for a few hours. The rest is history.

2017

First Lines of Code

tap

It started when his mom brought home a computer twice his age. He learned the basics from a kids' programming book that taught Scratch and Python.

2017 – 2021

The Self-Taught Era

tap

Self-taught HTML, CSS, and JS. Built early Python apps like music players and web scrapers — days spent digging through Stack Overflow before AI assistants existed.

2020

The Pizza Box Incident

tap

Disassembled a perfectly working antique Windows XP Thinkpad and tried mounting the motherboard inside a pizza box. Broke something along the way and it never turned on again. An expensive, time-consuming lesson.

2022

Pinecone School

tap

Attended Pinecone programming school and graduated with flying colors thanks to prior knowledge. Refreshing to finally have a real teacher to code alongside.

2023

GitHub & Real Teams

tap

Still at Pinecone, but leveled up the workflow. Learned Git, GitHub, and how to collaborate with real colleagues on everyday projects.

Early 2024

Linux VMs & Android Modding

tap

Set up his first Linux VM (Kali) and dove deep into ADB, scrcpy, and Android internals — building a reputation at school for formatting locked devices.

2024

The Unofficial School IT Guy

tap

Fixed teachers' laptops, HDMI cables, and forgotten passwords. Competed in a C++ olympiad (with zero prior knowledge of hashmaps or arrays—at least I tried!). Secured straight 100%s in informatics class every year, sometimes by 'borrowing' the Wi-Fi password.

Late 2024

The Arch Linux Switch

tap

Started dual-booting Windows and Arch. After a Windows update wiped un-pushed code, he nuked the partition, switched fully to Arch Linux, and never looked back.

2025 – Present

The TTS Era

tap

Continued pushing boundaries. Still playing table tennis and chess, but now with a focus on software and hardware engineering.
