Reduced timesheet approval time by automating routing, reporting, and conflict detection.
Fewer Errors
Improved operational accuracy by replacing manual review steps with structured workflows.
Manual Work Saved
Automated computer vision safety detection for factory and construction workflows.
Annual Cost Savings
Optimized warehouse robot behavior with sensor integration and reinforcement learning.
About Me
I'm a software engineer who earned a Master's degree in Computer Science from UC Davis in 2024. I build production-minded software with Python, JavaScript, Java, and cloud infrastructure, with a focus on systems that make teams faster and operations more reliable.
My experience spans full-stack development, backend APIs, computer vision, and data engineering. I enjoy turning ambiguous workflow problems into clear interfaces, automated pipelines, and measurable product outcomes.
