About Matthias Axel

Hello everyone! I am a Full-Stack Mobile Software Engineer with experience in Flutter, Go, Python, and web technologies such as NodeJS and React.

I hold a Bachelor of Science in Computer Science and several years of experience in the field, including a background in cybersecurity.

My expertise in Flutter allows me to create beautiful and functional mobile applications with fast rendering and intuitive user interfaces. I am highly proficient in the Dart language and popular state management techniques like Provider and BLoC. Additionally, I have experience integrating third-party libraries and APIs to enhance app functionality.
As a full-stack developer, I have experience working with a variety of front-end and back-end technologies, including HTML, CSS, JavaScript, React, Node.js, and SQL. I can work with both relational and non-relational databases and have experience designing and implementing scalable, secure, and efficient systems.

Regarding back-end development, my knowledge of Go and Python enables me to build robust and scalable back-ends. I have experience developing RESTful APIs, microservices, and web applications using popular Go frameworks like Gin and Echo, and Python frameworks like Flask and Django. I am well-versed in databases such as MongoDB and PostgreSQL and have experience working with Object-Relational Mapping (ORM) tools like GORM and SQLAlchemy.

My skills and experience in Flutter, Go, and Python make me a versatile and valuable asset to any software development team. I can work independently or as part of a larger team and am always eager to learn new technologies and expand my skill set. If you are looking for a dedicated and competent full-stack software developer, I am here for you!
