During this time at CAE Healthcare Hungary, worked on the LearningSpace product. Initially, work involved fixing bugs in the existing codebase, but later was tasked with standardizing the codebase and setting up CI pipelines. After that, started working on developing a new module. During this time, gained knowledge of the full stack and became a part of the architecture team. Main responsibilities included setting technology goals, introducing modern technologies, replacing custom solutions with industry standards, and optimizing processes.

Developed a map-based research result sharing portal for the Image processing laboratory in 2 months.

Design, implementation and operation of a production support solution (ordered by Foxconn). Worked with two students on the project, the software was completed in 9 months. After that, only minor fixes were needed. It has been used ever since. Created a full-stack solution for production line workers that assigns tasks and makes them easy to understand. As well as a user-friendly interface, which also improved production efficiency.

They deal with IT networking and operation. Developed a full stack solution for the existing invoicing program, which created analyzes of the issued invoices.
