Available to hire
Hi, I’m Nikolaos G. Nikolaou, a passionate full-stack developer and lifelong learner wuth a BSc in Computer Science at AUTh. I love turning ideas into scalable web applications, blending strong frontend skills with robust backend engineering, and continually refining my code with best practices. I’ve gained hands-on experience through university projects and internships, building responsive interfaces, RESTful APIs, and data-driven solutions.
In my full-stack workflow, I regularly use Angular with TypeScript and Tailwind.CSS for frontend development and .NET with C#, as long as nest.js for backend services. I work with SQL and DBeaver for managing databases. For testing, I used and have limited experience with Jenkins for testing and CI/CD with GitHub (and GitLab) with help of SourceTree. I am used to Agile methodologies, code reviews to my workflow for efficient development using Jira.
