I've been a software developer for 10 years, working for various international companies, with various technology stacks.
My focus for the last 3 years is in BackEnd development with Kotlin/Java. I've sucessfully implemented and maintain a Backend system with size around 100k LOC (Java/Kotlin).
I'm also always try to learn and catch up with new technology. Also started learning more about FrontEnd area.
Beside technical aspect, maintaing a long-term healthy relationship with clients is also what I've always trying to do, and it's been pretty good so far.
Hope I can help you with your projects at any stage.
