Denis' notes

Hey, I'm Denis Fedosov-Ledovskikh. I build small tools that strip away the overhead Open-source frameworks, CLIs and web apps. Two decades of making things for the web.

Why I built Micra.js

I remember when jQuery sat on almost every site. Before the frameworks, it was simply the easy way to reach the DOM: attach a handler, show something, hide something, fire a request. Back then that solved most of what you needed. Then the frontend got more complicated. Mostly for good reasons — apps grew, and React, Vue, and Svelte grew with them. But you don't always need that much.

What’s Wrong With Modern Email?

Email stopped being a simple (and maybe even convenient) tool a long time ago. After countless UI changes in Gmail, after hopping from one provider to another, I realized I don’t really trust email services anymore.
