Professional Experience

Jane Street Capital
Software Engineering Intern, FPGA & Network I/O Team New York, NY
May 2019 - August 2019

• Developed a zero-alloc userspace TCP stack, achieving latencies 4 times lower than Linux’s network stack
• Implemented a low-latency userspace network driver on top of Solarflare’s ef_vi kernel bypass, lowering response times by parsing packet headers before they are fully received by the host
• Wrote a network driver to feed ethernet frames into raw Linux sockets, allowing for userspace network stacks to be tested on arbitrary topologies when used in conjunction with network namespaces
• Modernized a cryptocurrency trading bookkeeping app, while reducing its memory footprint by 70%
• Technologies used: OCaml, C, x86 assembly, Solarflare ef_vi /OpenOnload, Linux kernel, perf

Google
Software Engineering Intern, Chrome OS Team Mountain View, CA
May 2018 - August 2018

• Securely implemented automated device setup using asymmetric crypto (via a device’s Trusted Platform Module), saving organization admins weeks every year when having to reset thousands of devices
• Developed robust runtime detection of device form-factor based on device capabilities (e.g. keyboard)
• Worked towards switching auto-update tooling to a newer protocol version using 5-10% less bandwidth
• Technologies used: C, C++, Python, Bash, protobuf, OpenSSL, Linux kernel, Gentoo/Portage, git/Gerrit

Ivy Global
Software Engineer Toronto, ON
2016 - 2018

• Implemented a ground-up rewrite and redesign of the company’s main website, ivyglobal.com
