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.
