Yoseph AI
Yoseph is an AI copilot for migrants navigating the U.S. immigration system. I'm building it as the person who lived the problem first: my own transition from TN to F-1, in real time, while writing the code.
Education & experience
Ten years in tech, most recently focused on ML systems and LLMs. Full detail is in the resume below.

Yoseph, and the work before it
Yoseph AI
Yoseph is an AI copilot for migrants navigating the U.S. immigration system. Most people in that position don't know what questions to ask, not because answers don't exist, but because the context is missing. A generic chatbot explains what a grace period is. Yoseph tells you how many days you have left and what to do today.
I co-founded Yoseph as a Delaware C-Corp and launched with 50+ users on day one, with zero paid acquisition. I'm the target user before I'm the founder: I built it while living my own transition from a TN visa to F-1.
Selected engineering projects
Document extraction with LLMs
Built an LLM-based extraction pipeline for invoices and business documents, taking accuracy from 50% to 85% and saving roughly $40K in manual processing.
Trends and sentiment extraction
Built an NLP pipeline for analyzing customer comments at 93% accuracy, work that helped retain $120K in client contracts.
Amazon Go and Alexa
Worked on distributed systems and ML inference across two of Amazon's consumer AI products: Amazon Go's checkout-free shopping experience and the Alexa voice assistant.
Data pipelines at scale
Built data pipelines and ML systems processing roughly 3TB of data per day.
