Ich habe an meinem Bachelor-Abschlussprojekt gearbeitet, bei dem es sich um eine mobile und eine Webanwendung handelt, die eine E-Parking-Lösung für Fahrzeuge bietet. Ich war mit .Net für die Back-End-Seite der Anwendung verantwortlich.

Ich war an der Entwicklung einer ASP.NET-Lösung beteiligt, mit der SUN-Server remote bearbeitet und die Ergebnisse über das Telnet-Protokoll auf einer Webseite angezeigt werden können.
