Backend Software Engineer

Lucas Alves

vulgo Lucas Dasial

Developing solutions for real-world problems for over +5 years through services and apps that make life easier for thousands of people and businesses every day.

I believe great software isn't defined by the programming language it's built with, but by its ability to solve problems in a simple, reliable, and sustainable way.
