Experience
Incoming Intern @ Summer 2026
DynamoDB Global Tables data plane team. Built an in-memory E2E testing framework in Java simulating multi-region replication locally, plus a fault injection layer for outages, network partitions, and latency. Reproduced real production bugs and got adopted by other teams.
Darwin Process Management (CoreOS) team. Built a Mach-based service launcher in C and Swift that reads a JSON dependency graph and auto-wires IPC between services. Replaced manual bootstrap registration with a dynamic handshake protocol for exchanging Mach send/receive rights.
Built and shipped a payment component processing $14M across 100k customers. Quadrupled Angular test coverage with Cypress and Cucumber, hitting 100% code coverage. Wrote company-wide docs on a new browser testing requirement that cut setup time by 50%.
Collaborated with two other devs to build a web app as part of a $50M enterprise project. Also improved the SonarQube score of a 200k+ LOC C++ codebase by fixing a large number of code smells.
Built a Python log navigator using Linux syscalls and Redis that saved operators ~30 min/day navigating Data Acquisition and Plasma Control logs. Added two new experiment metrics in Python that check thresholds on each fusion shot and alarm operators when crossed. Also built a C++ Qt GUI app for operators to control a reactor component that previously had no dedicated interface.
