Senior Full-Stack Engineer with 10+ years of experience
Hi, friend! I'm at my best if you want to talk about TypeScript/React and Elixir, but you will be surprised by the amount of tech in web stack that I know, or at least have an opinion on ;) I'm in the top 4% on StackOverflow and I'm in plenty of communities where I have a chance to help people with code or career advice.
If you are unsure if I'm a good fit, just ask for a free session.
If paid session didn't go well, you will receive a full refund, no questions asked.
If you are interested in hearing my "voice" you can check my Youtube, or find my contacts on my website.
What I usually write:
- web-based chat apps
- integrations with APIs
- secure and type-safe code
- great pull request descriptions
- hi (with the intention of checking your progress)

I started using TypeScript in 2014 even before it supported JSX :) if you know anything about TypeScript is that the hardest part of using it is when you work on a library and I did that a lot :)

I started with React pretty early, when Redux was considered a small library that one kid wrote and the real man use Flux. Which gave me a pretty good sense of what was happening with it, starting working with it before JSX was considered cool and you would use React.DOM.div for everything

This is not a typo :) I learned about Git from the famous 2007 presentation that Linus had. You can check that I signed up for GitHub just 3 days after it became public https://api.github.com/users/JLarky :)
I love git, I use it every day, I can rebase in my sleep and I fixed more broken git repos than normal people would ever have. I still learn something new though :) see https://twitter.com/JLarky/status/1475979210531303424

I learned Erlang for fun when I was at home for a few months without the internet. I found the idea pretty sound and I didn't see anything wrong with the syntax. I wrote few TCP/IP servers in Erlang and putting it on Github got me a job :)

rad-event-listener
Simple wrapper for addEventListener that returns a cleanup function so you don't have to call removeEventListener manually. The rad part is that it works with typescript 🤯

I prefer to have named exports in my React code and adding lazy loading for those is a bit of a pain, so I took this an opportunity to learn more about Proxy objects in JavaScript. I wrote the article "Jotai vs. Recoil: What are the differences?" and I had to learn a lot about Jotai for that one, so I knew that I could reuse their build system for this project to make the resulting package really small.

I was approached by LogRocket to write for them. It was pretty fun and required to do a lot of digging through source code and discord :)
