Hi, I'm Renan

I started programming many years ago and didn't figure out how to stop yet. I've worked in the industry, mostly in startups, I have my own SAAS and a lot of small open source projects. I like to keep things simple and small, and to under-engineer solutions to the problems I meet. You can contact me at renan@lecaro.me
