Projects

wFetch

OTIO Startup project

The fastest native Windows system fetcher, written in the Tauri framework.

C Rust React Windows API

Visuall

My most impressive project!

A compiled programming language with Python-like syntax, built on LLVM. Compiles to native machine code with O2 optimization, a mark-and-sweep GC, closures, f-strings, and a growing standard library. Comes with a full LSP server and a VS Code extension.

C++ LLVM Language Design LSP

GeoSentinel

A desktop app that shows active natural disasters on a real-time 3D globe, pulling live event data from NASA EONET with MODIS satellite imagery previews.

Rust React Three.js Tauri 2 NASA API

Consense

An Android app that sends your prompt to ChatGPT, Claude, and Gemini simultaneously, then synthesizes all three responses side by side.

Kotlin Jetpack Compose Android AI

yatuofetch

A Windows terminal system fetcher in C with glitch ASCII art animations, showing OS, CPU, RAM, GPU and network info at startup.

C Windows API

The Larkers' Codex

A Yaelokre themed notepad application with encryption. Not even Claude Opus 4.6 could break it!

C Encryption

Aleph

An array of linux terminal commands, written in Assembly.

x86 ASM Linux

STM32 Smart Compass

A GPS-enabled smart compass, co-developed at an electronics camp.

My Electronics Projects Journey

I started messing around with simple Arduino projects at 12, then paused for a while. At 13, I joined an electrical engineering course at school where I first learned analog circuits and simple microcontroller circuits with the ATmega16A. Later we moved to the STM32 for various projects using STM32CubeIDE. In winter 2024, I started coding in C, then x86 assembly. I've built countless projects and collected over 20,000 electronics components.
