Hi, I'm Sanat B Singh
I'm an AI Engineer and Tech Lead focused on Agentic AI, Generative Systems, and - on the research frontier - World Models. At ETS GCC (the org behind TOEFL and GRE), I co-lead product development across agentic systems, assessment simulation, and generative AI. Previously at Deloitte USI - fine-tuning LLMs on DGX H100 clusters and shipping edge vision pipelines on Jetson AGX Orin.
@ Work (ETS GCC)
- End-to-end platform and framework/library for interactive assessment - spanning simulation development, skill practice, and deployment at scale
- SLMs fine-tuned with PEFT for scoring and feedback
- Multi-agent prompt generation, evaluation, and benchmarking systems
@ Personal
- Actively researching and experimenting with World Models — causal, action-conditioned, intervention-aware generative systems
- Shortlist - AI screening layer for early-stage investors; deep research agents build investor thesis profiles and deploy an AI persona to conduct structured async founder conversations, surfacing signal from noise at inbox scale
- Reinforcement Learning
- World Models and Causal Representation Learning
- GPU programming & CUDA optimization
