At ROYALDIRKZWAGER B.V., I developed and maintained .NET backend components and APIs for maritime integrations. This included exchanging vessel and port call data with Port Community Systems and integrating data from shipping companies and maritime sources.
At BOOSTHIGH sp. z o.o., I developed API services for a driver's computer used in the Tricity public transportation system, in cooperation with Asseco Data Systems. I also developed a C#/.NET library for QR ticket printing devices and integrated the driver's computer with onboard routers.
At VIALUTIONS sp. z o.o., I developed REST APIs and backend services for S3 Connected Health's connected medical device platform supporting sleep apnea therapy. Earlier, I maintained a WMS at OPONEO.PL S.A. and developed business applications and a SharePoint portal at Logon S.A.
