• Currently, i can work with any JavaScript stack, front-end or back-end for mobile and webs apps. I quickly learn new libraries by reading the docs and applying them to solve problems simultaneously.
• I love the open source because the better techs are free and give to a lot of ppl including me the opportunity to get a better life from latam.
• I'm not interested in learning new languages to accomplish the same tasks. My focus is on solving real business problems. While all languages have their strengths, I prefer JavaScript for its ability to build full-stack apps with a single syntax. It's popular and constantly evolving with new tools. I'd rather spend my time solving problems than learning another syntax for the same purpose.

I been used a lot of differents libraries, so i just gonna say the major tools for every case that actually use more..

Language: Typescript
Frontend: React with Next.js, Tailwind for styling
iOS & Android: React Native with Expo.
Backend: Nodejs, Docker, Microservices, Nestjs.
Testing: i just use jest for all the platforms.
Cloud: Vercel, AWS.
IA: OpenAI models like chatgtp ect...
