Message

At FIS, I develop and scale backend services for an enterprise car leasing platform using C# and ASP.NET Core. I also design secure REST APIs for third-party integrations and optimized a SQL query that was slowing a data-processing task.

At Jaroslav Černi Water Institute, I engineered a Windows Mobile field application for Trimble Juno devices that automated data collection across more than 300 measurement points. I also built a WPF application to retrieve measurement data from FTP/SFTP servers and delivered backend components for a hydro-information system used by the Iron Gate I Hydroelectric Power Station.
