Tech Lead with PHP, Go, and React

I'm in the market for more than 15 years. Currently I'm a tech lead in an agency. I love working on exciting projects, learning new stuff and leading optimized solutions. As an example, our last challenge was a cron that had to be ran daily to do some heavy data crunching. It was a legacy script running in PHP. Problem is it was taking more than 24 hours to finish, so a new cycle would start before the last ended. I lead a refactor of this service as a micro service in go and the whole process now takes less than 10 minutes.
