I have over 10 years of experience working as a software developer, in telecom, mining, freight, real state, news, transport and automotive industries.

JavaScript
1140811 bytes

I write JavaScript, and TypeScript. I am comfortable with any runtime, be it, the browser, NodeJS, or Deno.
Learning Rust on my free time, in fact it is my go to language for coding challenges.
I have started to learn Swift, mainly by building iOS apps on xcode, and occasionally using it to solve coding challenges.
