01.About Me
I'm a software developer working mainly on backend systems, AI products, and automation.
I like being involved from the start: understanding the problem, turning an idea into a clear scope, and building something the team can maintain and grow.
Over the years I've worked with Node.js, TypeScript, Python, Elixir, and Go, both on new products and systems already running in production.
