Full-stack Developer React / .NET @ Sherweb
About
I have 25 years of experience mainly in web development. I do not believe that one technology meets all needs; this is why I am interested to Linux, C++, Python, Javascript (Angular, React, VueJS), Java (Scala, Kotlin, Clojure), NodeJs, MongoDB, AWS, Azure and the others. I stood out by my creativity, my determination and ability to adapt. I believe in periodic deliveries, well-crafted software and allowing all programmers in the team to grow at their own pace. I am passionate about the progress of software development. That is why I always have an active subscription on the important sites dedicated to computer training. My goal is to contribute to the professional team conscious that a technical or human detail can make the difference in the delivered result. Here my GitHub profile: https://github.com/tsawyer999
