Projects
Bug Tracker 02/2023 – 06/2023
Created a bug-tracking system that offers a thorough and efficient method for monitoring and managing
software defects and issues throughout the software development lifecycle.
Bug Tracker was my diploma project, and with my confidence and passion for the project, I received a 90/100
score during diploma defense and made it into the top 5 in the class out of 22 students.
All the stages of the app development were designed by me, such as architecture, diagrams, database,
UI/UX, coding, and troubleshooting; so, I can manage projects and be flexible no matter the task.
