1) Plain PHP. I started my career as a developer with plain PHP. Not with frameworks. But keeping in mind the scale of modern applications and time restrictions I started to use frameworks. But if you have an old website built completely with plain PHP don't worry so that I have experience in maintaining such things.
2) Yii2. It is my very first PHP-framework.
3) Laravel. It is my hands-on framework and I'm using Laravel almost everywhere incluing API development.
4) VueJS. Thought I'm backend developer but since Laravel is shipped with VueJS I decided to learn it and VueJS became my first JS-framework. Starting using it only to add some dynamic to Laravel-based webapp now I'm creating SPA (Single Page Applications, when you browsing page by page without reloading almost instantly) based on VueJS. Developing with VueJS I'm using Vuex, VueRouter and some other Vue-sattelite features.
5) jQuery. Now it is outdated technology and I try not to use it at all. But if you need support with jQuery I'm ready to help you.
6) Docker. Now I'm using Docker for deployment. Fast, maintanable and no-risky enviroment. Whatever hosting you have we can test it in Docker first.
7) If time allows I try to write the tests for my code. It of course depends on each particular situation and goals that the Client are having.
8) Git. I always use git and can't image how it is possible not to use it. Always working in my own branches, can revert commites and cherry-pick particular details. Have accounts on GitHub, BitBucket and GitLab.
