Me Myself and I

Hello I'm Pawel!

As a passionate Senior Fullstack Engineer, I enjoy the art of coding and building reliable, scalable products. I believe that the key to growth as a developer is to constantly seek out new challenges and develop a broad range of skills. Over the years I've grown from frontend expertise into backend development and cloud architecture — working with serverless solutions on AWS to build fast, cost-efficient APIs.

When I'm not working, I like to explore new ideas in cloud-based solutions, honing my skills and staying up-to-date with the latest trends. Beyond tech, I also have a love for literature and video games, and I make it a priority to take time out of my busy schedule to enjoy these hobbies. Whether I'm immersed in a great book or outside exploring nature, I believe that finding balance between work and play is key to staying motivated and engaged in all areas of life.
