Full-time

- Established the foundational automated testing framework for RPM and Kubernetes operator builds, transitioning the project from high-risk manual verification to a fully automated CI/CD pipeline. - Mitigated potential production incidents by an estimated 30% within the first month by architecting and implementing the project’s first suite of automated integration tests. - Modernized legacy testing infrastructure, increasing unit test coverage to 90% and ensuring high-fidelity code validation across the operator lifecycle. - Optimized container images, achieving a 40.4% reduction in size (60.6 MB to 36.1 MB), significantly accelerating deployment velocity and reducing resource overhead in Kubernetes environments. - Automated batch processing stages for Knowledge Base datasets, accelerating the data delivery pipeline for LLM fine-tuning cycles. - Built project PLX Dashboard and automated fetch report data from GitHub using App Script for ticket automated reporting.

Full-time

- Orchestrated a mission-critical vote count pipeline for Eleksyon 2025, maintaining 99.9% uptime during a high-stakes 24-hour live national broadcast. Architected a resilient real-time data flow from COMELEC to network servers, ensuring zero-latency delivery and accurate reporting for nationwide media coverage under extreme peak-volume conditions. - Developed a custom GPU-accelerated data reader from scratch in C++/R, leveraging GPUDirect Storage (GDS) and cuDF to bypass CPU bottlenecks. This breakthrough reduced CPU overhead by 85% and improved script performance by 80% for massive CSV datasets, transitioning complex processing tasks from hours to minutes via optimized hardware-to-GPU data orchestration.
