Hello, I'm Eslam Mohamed. I'm a Backend developer passionate about building scalable and real-time systems. I enjoy building sites & apps. I specialize in Node.js (Nest.js).
About me
During my degree in Computer Engineering, I decided to pursue my passion for programming. I enrolled in a coding bootcamp and learned full-stack web development. My favorite part of programming is the problem-solving aspect. I love the feeling of finally figuring out a solution to a problem. My core stack is Node.js, Nest.js, MongoDB, and PostgreSQL. I am also familiar with TypeScript and Mongoose. I am always looking to learn new technologies. I am currently looking for a full-time position as a (Backend) developer.
When I'm not coding, I enjoy playing video games and doing exercises. I also enjoy learning new things.
