My strong sides are Node.js/Express and PHP/Laravel backend frameworks. Also, I use Angular 7, React.js and Vue.js on the front-end. Though, learning a new framework isn’t an issue for me.
On one of the last projects, I had to learn Go. No problem at all! I created a microservice for AWS Lambda using Go. It was a service for geodata and search.
Besides, I use Python for deployment scripts and for some of my pet-projects.
I have good experience with DevOps too: I always write scripts for automated deployment. I worked with Jenkins CI, Travis CI, Bitbucket pipelines and so on.
