HFrom Curiosity to Mastery

About ToH

ToH stands for Zero to Hero. It is a knowledge platform where I turn real-world engineering experience into clear, practical understanding — and share it so others can grow too.

I kept repeating myself. Answers lived in scattered notes, chat threads, and half-finished documents. ToH is where the good ideas settle, get refined, and become shareable.

What this is

A single source of truth for my long-form writing: articles on software engineering, AI, system design, and building products. Every post is written to be genuinely useful, easy to read, and easy to find.

Why it exists

I kept repeating myself. Answers lived in scattered notes, chat threads, and half-finished documents. ToH is where the good ideas settle, get refined, and become shareable.

What you will find

  • Blog posts — long-form, search-friendly articles.
  • Docs — guides and references (coming soon).
  • ADRs — architecture decision records (coming soon).
  • Prompts and snippets — reusable building blocks (coming soon).

How content is made

Every article is authored in Markdown, version-controlled in Git, and published through a static build. No database, no CMS — just clean, portable content that is fast to load and easy to maintain.
