Calibrated Decisions at the Human–Robot Boundary
Decision layer between robot planner and policy
Investigated the decision layer between a robot's planner and its policy (act, ask, or hand off to a person). Tested calibrated models against frozen rules and an oracle on four simulated bodies across 160+ experiments. Distilled a 421M-parameter on-device model from a cloud judge, maintaining 88.3% accuracy versus 87.9% for the cloud version at 90ms latency with calibration intact. Identified a failure mode in fleet learning where retraining on operator takeovers can make models confidently wrong outside corrected regions.
Experience
Software Development Engineer II
AmazonAug 2022 — Jul 2024 · Seattle, WA
Building next-generation personal AI agents, owning the runtime for long-horizon durable work and the proactive layer that listens for real-world changes. Led the agent's prompt-caching program, improving cache hit rate from 45.6% to 83.0% while reducing latency by 57%. Led the Alexa+ notification domain rebuild, designing the model interface and evaluation harness for ~90M customers. Designed a platform primitive for deterministic service actions and contributed to the real-time proactive content system, which achieved 26x engagement improvement.
Machine Learning Research Intern
Lawrence Livermore National LaboratoryJun 2021 — Aug 2021 · Livermore, CA
Designed and trained an LSTM in PyTorch for sequence labeling over raw binary data, classifying non-code byte regions in PE and ELF binaries at 95%+ accuracy. Built an approximate nearest-neighbor retrieval system for software origin tracing using NMSLIB, returning k-nearest neighbors for newly ingested binaries against an enterprise corpus. Extended the work through spring 2022.
