Most people use technology. Here, we truly understand it.

This channel is about deep software engineering — from building native React Native libraries with JSI and C++, to understanding the engineering behind the tools and applications we use every day.

I explore WebAssembly, WebGPU, and high-performance systems to understand when it makes sense to move beyond JavaScript and why some problems are better solved with lower-level languages.

I also explore how games, emulators, and engines work internally — the algorithms and engineering decisions that make complex real-time systems possible.

Sometimes I build physics engines, VSCode extensions, and custom tools to explain concepts in a practical way.

For developers who want to go beyond tutorials — the ones who want to truly understand how the applications, tools, and systems they use every day actually work.
