About Me
Hi, I'm Jakub Lewandowski
My journey in web development began with a curiosity for building engaging digital experiences. Since then, I've developed a solid foundation in fullstack development, with a particular strength on the backend — especially working with NestJS.
Currently, I'm working at BlockWise as a Junior Python Developer, where I build and deploy machine learning models.
Outside of work, I enjoy exploring new technologies — lately, that curiosity has led me to dive into the fundamentals of machine learning. I'm currently focused on learning how to build and train models from scratch, and understanding the core principles that power intelligent systems. You'll also often find me on the badminton court, unwinding with a good game.
