Things I’ve built and studied

From a patented generative layout system to GPU cluster analysis: mostly AI, with a systems streak.

US Patent 12,169,850 B12024

Content and layout control for generative systems

A granted US patent on controlling both content and layout when generating marketing visuals with generative models. The system I built during my MScAC internship at Ecomtent later became part of it.

Generative AI for product listings and infographics

Designed and built the ML system behind Ecomtent’s AI-generated product images and infographics: diffusion models for imagery, layout-generation networks with constraints on position and size, and stateless API endpoints on AWS.

Systems analysis

MLaaS 6.5k-GPU trace analysis

Analyzed scheduling fairness in a 6.5k-GPU production cluster trace. Finding: wait times on low-end, shared GPUs are distributed more fairly than on high-end ones.
