Work

Built an EMR cluster core capacity prediction system for the S3 Express One Zone metering service, deployed to production regions and cut metering costs by ~65% while keeping cluster runtimes predictable.

At Cresta, I supported the development of data integrations and pipelines, across the frontend (React) and backend (Go). I gained a solid understanding of cloud technologies, particularly AWS, and Infrastructure as Code using Terraform. I also developed CI/CD pipelines using GitHub Actions and a custom E2E testing framework using Playwright.

At PTX, I contributed to the development of a cutting-edge, real-time 3D detection system. Specifically, I designed an efficient, multi-threaded pipeline in C++ (Qt5 framework) to process 3D point clouds effectively. I also integrated a GPU-accelerated Simultaneous Localization and Mapping (SLAM) algorithm into the system. This successful integration resulted in a ~10x speedup in processing time.
