Continuing Education

Education

  • University at Albany, State University of New York

    • Bachelor of Science in Computer Science

    2018 - 2020

    While at the University at Albany, I acquired a strong software development foundation and developed and honed my teamwork and communication skills through collaborative projects and team-based assignments. Additionally, I gained valuable experience in project management, coordinating tasks, setting deadlines, and ensuring the successful completion of various projects. While our focus was primarily on software development, I have applied these skills effectively in my day-to-day work.

    I am proud to have graduated cum laude and consistently maintained a high academic performance, achieving a cumulative GPA of 3.49 throughout my academic journey. Additionally, I was honored to be awarded the Spellman Academic Achievement Award for my performance. This recognition further motivates me to strive for continued growth and success in my educational and professional endeavors.

    In addition to my academic achievements, I had the opportunity to collaborate with a team on a Software Engineering project called "Test Maker". This collaborative effort involved developing a web application using a robust technology stack that included Microsoft Azure, Azure SQL Database, and ASP.NET (C#).
