BloodyCoTech is my personal corner of the web. I use it to make my learning visible: notes I have checked, interview topics I am actively revising, and small web products that can be opened and tested.
Why this site exists
Bookmarks are good for collecting links but poor at proving understanding. Writing forces me to choose an example, name a trade-off, and notice what I still cannot explain. When an article becomes outdated, I want the date and source links to make that visible too.
What I write about
The current focus is frontend engineering: React, TypeScript, browser APIs, responsive interfaces, web performance, and the small game systems that make the browser fun to work with.
Ground rules
- No invented clients, users, download counts, or testimonials.
- Examples should run or be type-checked where practical.
- A project gets an honest status: experiment, active build, released, or archived.
- Corrections are welcome; quiet confidence is better than pretending to know everything.
Start with the interview training room, or read the Vietnamese technical notes.
