Hi, I'm Matt! I'm a Software Development Engineer (SDE II) at Amazon in the Greater Seattle Area, currently working on large-scale challenges within AWS Billing since June 2020. I lead a talented team of 12 engineers building and running the core platform that calculates bills for over 30 million AWS customers. I also spearhead the technical side of internal compute interfaces that handle billions in daily billing throughput. Security is another passion – I serve as the technical security lead for our ~150-person org, driving best practices and having implemented an automated patching solution for over 12,000 servers. I also enjoy mentoring junior engineers and interns.

Before Amazon, I co-founded calculated.gg, where we developed Paragon, a training app for Rocket League. As a lead developer there, I focused on the cloud backend (AWS Lambda, DynamoDB) and C++, while also dabbling in Rust/Typescript for desktop work. Earlier, calculated.gg ran a popular website analyzing Rocket League gameplay using stats and ML, built on data from millions of games and players. I handled all the DevOps/cloud admin (GCP) and was the lead backend Python dev for that. We also maintain carball, the open-source replay analysis package that powered it all. That work is completely open-source so check it out!

This work led to consulting opportunities with Psyonix, the makers of Rocket League. From late 2019 to mid-2022, I helped develop esports software for the Rocket League Championship Series (RLCS), using a mix of Rust, Typescript, React, and Python.

I graduated from Northeastern University in May of 2020 with a Masters in Mechatronics/Mechanical Engineering. At Northeastern I was heavily involved in the Northeastern Esports Club, including being one of the founding members and the technology director. I was also part of the Club Rocket League team and was on the original roster and helped to promote the team to varsity status in Fall of 2020.

Outside of work I take photos, hike, cycle, ski, and play competitive games (Rocket League, SSBM), as well as tabletop games when I have the time.
