Hi there, I'm Spandan 👋

😄 A bit about me:

• 📊 I’m currently a Data Scientist II at Microsoft (2020 - Present), working on building AI-powered Software Performance tools for C# and .NET applications.
• 🎓 I recently completed my undergrad in Software Engineering at the University of Waterloo (2015 - 2020).
• 🎨 Outside of work, I enjoy sketching, running and a few racket sports like Table Tennis and Badminton.
• ⚡ Fun fact: Prior to Data Science, I worked in Game Development. Thanks to that, I have my very own IMDb page from my work on Luigi's Mansion 3 as an intern at Nintendo (Next Level Games, Inc.).
• 💬 Feel free to reach me at: spandan.garg1706[at]gmail.com

Please visit my website to learn more about my current and past research projects and publications!
