Matthew Mage

Principal Engineer at Palo Alto Networks, on the Chronosphere integrations team. Early days.

Before that, six years at Amazon on AWS Billing, the platform that bills ~20 million AWS accounts. I was tech lead on the compute-path rewrite that shipped in 2026, and security lead for the org. A patching pipeline I built got 12,000+ hosts from 10% to 99% patched.

Before Amazon I co-founded calculated.gg. We built Paragon, a Rocket League trainer; earlier we ran a replay-analysis site for tens of thousands of players. I owned the backend (GCP, then AWS Lambda and DynamoDB) and wrote most of the Python and Rust. The replay engine is open source: carball.

From 2019 to 2022 I consulted for Psyonix on the Rocket League Championship Series.

BS/MS in Mechatronics at Northeastern, 2020, with a stint at NASA Ames on satellite-reflectance ML in the middle. While at Northeastern I helped start the Esports Club, ran its tech, and was on the founding Rocket League roster when the team made varsity in 2020.

Outside of work I take photos, hike, cycle, ski, play Deadlock, and run the occasional D&D campaign.
