What I'm looking for

I’m looking for a role where I can build web and backend features using modern React and Node/NestJS, improve performance and UX, and grow by shipping user-centered, maintainable solutions in a collaborative team.

I’m an M.Sc. student in Computer Engineering with practical experience in web and backend development. I’ve worked across professional roles, internships, and personal projects using React.js, Node.js, NestJS, TypeScript, MongoDB, and WordPress.

As a Junior Webmaster & Web Designer, I develop and maintain WordPress websites, implement responsive UI/UX with Elementor and WPBakery, and optimize performance using techniques like lazy loading and asset optimization. In freelance work, I build RESTful APIs with Node.js/Express.js, use TypeScript for reliability, integrate MongoDB for CRUD and schema design, and test endpoints with Postman.

I’m passionate about software development and I actively improve my technical skills by building modern, optimized, user-centered solutions. I also enjoy shipping features end-to-end—such as a React + NestJS + MongoDB Expense Tracker and interactive education projects using HTML/CSS/JavaScript and face-api.js.
