Savvy Raghuvanshi

Systems Engineer and Financial Analyst
Harvard Class of 2022

• ~ Redesigned the distributed web backend for horizontal scalability and led a team of 5 to implement it over a period of three months. The final backend perceptibly improved application launch time.

  ~ Architected, implemented, and maintained another core production backend service for over a year.

• ~ Built and deployed a SMS-based COVID test kit activation system for Harvard students with 160 signups and 731 activations within 2 weeks of launch.

  ~ Developed and deployed a solution for Linux users to connect to Harvard's legacy printing system. ↗

• ~ Invented a novel process-safe method to parallelize MongoDB traversal in Python. ↗

~ Integrated the PicoTCP↗ user-level networking stack into the Alto runtime, enabling fast snapshot and restore of VMs. Also added limited networking event-driven capabilities to Alto.

~ Implemented seccomp system call filters to isolate client code. Significantly reduced the set of required system calls, exposing a tiny attack surface compared to Docker.

~ Redesigned the Alto hypervisor so client code would no longer run with root privileges.

~ Closed a font-based fingerprinting side channel in Google Chrome, improving both blocking performance and end-user experience compared to previous font-based fingerprinting blockers.
