Back to original languageAbout Karim
I am a Full-Stack Web Developer with over 8 years of experience in web development.
I am accustomed to working on projects where I am responsible for both the backend and frontend, on both public-facing websites and business tools.
Backend: I am used to working with Symfony coupled with API Platform to quickly develop robust RESTful APIs relying on JWT for security.
Frontend: I use React.js, VueJs, JQuery, and Javascript ES6 to ensure server-side rendering and thus guarantee the SEO optimization of the sites I develop.
I handle the HTML/CSS part using Bootstrap and React.js (JSX).
For databases, I work with MySQL and SQL Server, whose SQL dialects I know perfectly. I also have good knowledge of performance tuning.
For DevOps, I use Docker, Github Actions, or GitLab (CI/CD).
For teamwork, I use Git, Github, Atlassian products (Jira, Confluence, Trello, ...), Slack, Teams, ...
Do not hesitate to contact me by message if you want more information, I respond quickly.
