About

I hold a Master’s and Engineer’s degree in Computer Science from the Wrocław University of Science and Technology, both achieved with top honors. My master’s thesis involved developing a novel method for recognizing American Sign Language using Convolutional Neural Networks and transfer learning, while my engineer’s thesis focused on creating a mobile application for monitoring patient health information via iOS and Apple Watch. Throughout my academic journey, I’ve built a solid foundation in AI and machine learning, which I have continued to explore and apply in my professional career. My professional experience spans various roles in iOS development, working with companies like Varjo, Stepstone Services, and Deviniti, among others. At Varjo, I contributed significantly as a 3D iOS Developer, enhancing app performance and implementing offline databases for 3D scans. My tenure at Stepstone Services involved improving app performance and user experience, and pioneering a new app architecture using SwiftUI. Additionally, I have extensive experience with various technologies, including ARKit, CoreMotion, Swift, SwiftUI, and CI/CD tools, and have been involved in diverse projects ranging from banking apps to health monitoring systems, consistently delivering high-quality, innovative solutions.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
