Work Experience
Senior Applied Scientist
Amazon
January 2025 - Present
At Amazon, I'm an AI researcher working on LLMs for coding. I've been responsible for helping post-train our latest model release, Nova 2 Pro. My focus is on improving how these models reason and write code through reinforcement learning.
AI Researcher
Pika
January 2024 - January 2025
At Pika, I was a researcher working on the company's generative AI models for video. I led data curation for large-scale pretraining and owned much of the post-training stack. That work powered a range of user-facing fine-tunes like Pikaffects, and I also fine-tuned multimodal LLMs for video captioning, categorization, and retrieval.
Co-Founder & CTO
Humanlike
May 2023 - December 2023
At Humanlike (YC S23), which I co-founded and ran as CTO, I built low-latency, realistic AI voice agents that automate business phone calls using LLMs and generative speech models. I led engineering and product end to end, from the first prototype to landing enterprise customers. We went through the YCominbator S23 batch.
Staff Machine Learning Engineer
Snorkel AI
July 2021 - May 2023
At Snorkel AI, I was a staff ML engineer and tech lead for the structured-documents product, which let enterprises extract, label, and classify data from PDFs and other documents. I brought foundation-model workflows into the platform — embedding search, prompt-based labeling, and LLM fine-tuning with document-specific models like LayoutLM — alongside integrations with Snowflake, Azure, and Databricks.
AI Researcher
Uber
May 2017 - November 2019
At Uber, I was a research scientist in Uber AI Labs, the company's artificial-intelligence research group. I worked on reinforcement learning and computer vision, specifically for self-driving cars and to optimize Uber Freight surge pricing. Was also involved in building an AI customer service agent that saved the company tens of millions of dollars annually.
