    As a highly skilled software engineer based in the vibrant city of Leiden, just a short distance from Amsterdam, I am dedicated to solving complex computer science problems and developing innovative software solutions. With a strong background in a variety of programming languages, including C, C++, Python, and JavaScript/TypeScript (Node.js), I have the technical expertise to tackle a wide range of software development projects. This includes creating new software from scratch, extending or modifying existing software, and developing small scripts to execute specific programs. In addition to my programming skills, I have a keen understanding of algorithms and their time complexities. I am skilled at designing and modifying algorithms to meet the specific needs of a project. Working with databases is also a strength of mine, including designing relational databases and building queries using SQL and R, as well as extracting data from various sources such as databases, APIs, and websites. Implementing continuous integration and continuous delivery (CI/CD) processes can greatly improve the efficiency and reliability of a software project, and I have experience doing so. I am also proficient at designing and developing APIs using tools like OpenAPI/Swagger and have experience connecting to or implementing existing APIs in various projects. I have a strong background in containerization technologies like Docker, including creating and pushing Docker images and setting up Docker Compose configurations. In addition to my back-end development skills, I am also experienced in web development using Node.js. Proficiency in LaTeX is another one of my skills, and I am happy to assist with formatting and creating professional documents or notation. I am also available for consultation on any of the subjects mentioned above and am eager to collaborate with you on your project to bring your software ideas to life.
