Over the last 10+ years, I worked on a variety of web applications using PHP, NodeJS on the backend and ReactJS on the frontend. My skills are: - Backend development: PHP, NodeJS, SOLID, Design patterns (Repository pattern, Decorator pattern etc.); - Frontend development: ReactJs, Angular; - Strong skills in AWS; - MySQL database architecture design and slow query diagnosis; - QA: writing unit, functional, acceptance tests (including selenium), javascript and React tests; - Good team/solo player. I'm seeking for a part-time/casual temporary employment/contractor position.
