About Philip

Hi, I'm a Research and Development Architect (software engineer) at Jump Trading in Chicago. I was formerly a PhD student in the computer science department at Rice University (July 2021), a Master's student (M.S. Computer Science, May 2018), and an undergraduate student (B.S. Mathematics, B.S. Computer Science, May 2017).

I'm happily employed and not looking for a new position, but I'm always open to hearing about opportunities in Houston or Dallas (not remote).

I love hard problems, running, thinking, programming, and reading. I'm passionate about technology and engineering.

During summer 2019, I interned in the Linux and R&D teams at Jump Trading exploring InfiniBand network congestion. The two summers before, I worked with Ian Karlin at Lawrence Livermore National Lab studying the impact of network congestion on HPC applications. Prior to that, I worked on HPC performance analysis with Chevron's Emerging Technology group (2016), Azure Service Fabric with the Hyper-scale Compute team of Microsoft Azure (2015), the Oxbow project with the Future Technologies Group at Oak Ridge National Lab (2014), and HPCToolkit at Rice University (2013, 2012).

Selected Personal Projects

When I found that Mali does not follow the normal rules restricting Unicode characters in domain names, I knew I had to build this. It's a firework simulator game I built for HackRice 2016. Uses SignalR and websockets to allow for a real-time multiplayer firework experience.
C Preprocessor Debugger
After struggling with macro expansion and the C preprocessor, I decided to build a tool to help. This Clang plugin shows you how the preprocessor recursively expands your macros, one step at a time. I also built a browser-based version.

Tasks and Calendars
A personal Universal Windows Platform app that helps me manage my integrated to-do list and calendars, all stored on SharePoint 2013. I gained experience with the SharePoint CSOM and with writing Universal Windows Apps.
Password Manager
A password manager that does not require a master password but instead uses certificates and an additional second factor when connecting from a remote network. I learned more about certificates, managing a PKI, and writing client-server applications.
