After joining an IT company as a new graduate, I have been working in roles related to databases. Starting in January 2024, I will begin taking online graduate courses in computer science at Georgia Tech while working. I have created this blog to share what I learn in graduate school, and I plan to update it regularly. I will include class notes and other materials, so please bear with me if things are not perfectly organized or if there are some discrepancies. Additionally, all content shared here reflects my personal opinions.
