About me

Jens-Mikael Stjernberg

<> I'm 17 years old and speak English, Swedish, Finnish, and Norwegian fluently, and also a bit of German. I have been programming for around 4 years now. I initially began with game development using Pygame in Python, but afterward, I gravitated more toward web development and have been passionate ever since about building beautiful web applications with TypeScript and Tailwind in Next.js. Recently, however, I have been focusing more on the architecture of web apps and striving to enhance the performance between the client and backend in the most secure way. I've started learning about databases and authentication with Firebase, SQL databases with DrizzleORM, and OAuth services.

Despite being in high school, I mostly spend my free time programming and playing music. I also highly value health, so when I'm not in front of the computer or with my guitar, I go to the gym and train until I can't lift my arms anymore. Either way, I love learning and having fun solving problems, which is why I believe I could be a great developer for your business. </>
