Self-taught developer / Systems notes

A quiet place for

05 Bytecode

06 VM

Runtime

The place where code receives memory, values, limits, and a world in which to run.

Bytecode

The compact instruction layer between source language and machine behavior.

Virtual machine

A machine made of software that reads those instructions and enforces their boundaries.

The road so far

Not a straight line.

2015

Blogger and HTML. The first small changes that made the hidden structure of a website visible.

2018

A friend's coffee shop and a Firebase night. Dependency stopped being an abstract technical word.

2020

Home, delivery work, and Kitstack. Real projects began shaping a private Go platform.

Now

Opening the useful parts. Kitwork, concepts, articles, and source code turn private lessons into public material.
