About Alexander Kuzmenok
Home → About
I'm Alexander Kuzmenok, a Node.js & JavaScript developer and the author of Code with Node.js. I build and ship Node.js and JavaScript for a living, and write here to explain how things actually work — the APIs, the packages, and the sharp edges I hit along the way.
Everything published here comes from hands-on work — real projects, real bugs, and real trade-offs. When I research an npm package or explain a Node.js API, I've run the code, hit the edge cases, and written down what actually happened rather than what the docs promise.
If a post is wrong or out of date, I want to know. The fastest way to reach me is LinkedIn ↗, or through the contact page.
What I write about
- Node.js and JavaScript internals, explained from working code
- Practical, copy-pasteable snippets that solve one problem well
- Honest npm package research — what to use and what to avoid
- Build pipelines, servers & APIs, browser automation, and data processing
