Mateusz portrait

Hello, I'm Mateusz. I'm a backend oriented full-stack developer with 3 years of experience. I enjoy building sites & apps. My focus is Node.js (NestJS) and React (Next.js)

About me

Recently graduating with a degree in Computer Science, For the past 2 years I was mainly building backend infrastructure but now I want to embrace more challenging projects as a full-stack web developer. 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, NestJS, React, Next.js and MongoDB/Firestore. I am also familiar with PostgrSQL, Java, C# and Python. I am always looking to learn new technologies. Don't be discouraged if one buzz word is missing from the list because at the end of the day I can quickly expand my knowledge about specific topic. I am currently looking for a full-time position as a software developer.

When I'm not coding, I enjoy running. I also enjoy learning new things. I am currently learning about building long term investing systems for cryptocurrency markets. I'm also learning how to speak Japanese, although Kanji still makes my mind go blank.
