About

Here is a little background

I am a Full Stack Developer with experience in React, Next.js, TypeScript, Node.js, Supabase, and Python, building dashboards, CRM systems, API integrations, and web applications for agencies and startups.

I also have over 10 years of experience at the Paraná State Court of Justice, where I contributed to the digitalization of judicial processes and the implementation of the eProc system. This experience provided me with a strong foundation in organization, process analysis, and management.

I hold a Bachelor's degree in Business Administration and a postgraduate degree in Software Engineering. Beyond technology, I have a strong interest in statistics and enjoy learning new languages, right now I'm getting better at French and studying Chinese Mandarin.
