About Me

I'm a Senior Data Engineer at AARP with a M.S. in Computer Science (AI/ML) from Georgia Tech and a B.S. from Johns Hopkins. I specialize in architecting scalable data pipelines, cloud infrastructure, and ML-driven solutions — having generated over $380K in annual savings through AWS and Databricks optimizations while supporting a $700M business.

Beyond data, I have a deep passion for computer graphics. At Johns Hopkins I built a raytracing engine with BVH acceleration and soft shadows, an OpenGL rendering pipeline, a keyframe animation system, and an image processing suite. At Corfix Project, I developed interactive 3D heart model visualizations using vtk.js and WebGL to enable patient-specific medical solutions.

I also contribute to AI advancement as a Software Engineer Expert at Handshake AI and Data Science Expert at Mercor, where I develop gold-standard solutions and curate training data to improve state-of-the-art Large Language Models.
