About Me

I graduated from Yıldız Technical University in July 2022. Before that, I worked as a part-time student at Siemens for one year. I was involved in a project called "Digitalization," which aimed to analyze government incentives provided to R&D companies. Our task was to track the entrances and exits of employees and report this data to the accounting team. The project was written in the C# language and .NET framework. I made developments to simplify the reporting process.

After graduation, I started working at TEB (Turkish Economy Bank) as a Full Stack Developer, and I continue to work there to this day. I am a member of a team known as "Red Card," which primarily focuses on converting Oracle Forms screens into Java-based interfaces. For this, I utilize Java as the backend language, JSF for the frontend, and Oracle PL/SQL for database development. I am actively involved in the creation of numerous new screens as part of the team's projects, and I also occasionally work with Jasper reports.
