Building intelligent systems
that see, think & act

Sahaj Kishorkumar Mistry

I'm an Applied Scientist with 2+ years of industry experience in multimodal AI, vision-language models, and generative pipelines, complemented by a strong research track record: 4 publications at CVPR, MICCAI and ICASSP, and a paper on speeding up multi-agent LLM systems under review at ICLR 2027.

My expertise spans agentic AI frameworks (LangChain, LangGraph, CrewAI), on-device model optimization (INT8 quantization, ONNX, TensorRT), and scalable ML inference (Triton, GKE, Cloud Run). I'm currently pursuing my M.Tech in Machine Intelligence & Data Science at IIT Delhi, working with Prof. Sayan Ranu, and our team placed in the top 10 of 32,000+ teams in the Amazon ML Challenge 2026.

ProSpect: Faster Multi-Agent LLM Systems

โšก

Lossless speculative execution for multi-agent LLM systems. Predicts which agent runs next (link prediction over an agent graph mined from past traces, with a lightweight GRU) and what it receives (a speculator LLM with retrieval-augmented in-context learning), then runs it early and keeps only correct results.

๐Ÿš€ 17โ€“38% faster, identical outputs ๐Ÿ“ˆ 6โ€“28% better than prior SOTA
