About

As a seasoned Mobile Architect with over a decade of experience in Microsoft technologies, I have a strong track record of developing and leading mobile and server applications. My expertise lies in crafting mobile solutions using Xamarin and building robust server-side applications with .NET Core, hosted in the Azure cloud. At Sii Poland, I spearhead the architecture and management of the SiiApp, a comprehensive internal tool for time reporting, leave requests, and employee searches, serving both iOS and Android platforms. Throughout my career, I've played pivotal roles in various companies, including ITMAGINATION and Appriss, where I contributed to the development of innovative solutions while also conducting technical recruitment interviews. I'm passionate about sharing my knowledge through blogging and speaking at conferences. Outside of work, I enjoy delving into the world of single malt Scotch whisky and exploring the nuances of different flavors. My blend of technical acumen and leadership skills makes me a valuable asset in any tech-driven environment.

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. “
