AI Systems Engineer
I design AI systems that behave credibly under real use — multi-agent orchestration, retrieval, and the evaluation and serving layers that decide whether any of it survives contact with users.

Things I've built
AI systems engineering and low-level ML, shown as I actually split my time.
PocketPatient
A production clinical trainer where learner nurses interview AI patients that hold character across sessions: 40+ cases across 8 specialties, structured feedback, and a retrieved (not prompt-loaded) case library.
- median session-turn latency1.8s
- 30-day learner retention67%
RepReady
Enterprise roleplay where a sales rep negotiates with an AI buyer who holds a persona, objections, and history across sessions. Two agents in the loop, five published system layers, human-evaluated conversation quality.
- conversation quality vs human roleplay4.1/5
- median practice sessions per rep6sessions

What people say
Arjhine is the rare engineer who treats evaluation as a first-class deliverable. The regression harness she built cut our release cycle in half, and the team still quotes her rubric standards in design reviews.
Maria Santos
VP of Engineering, Northstar Health
Pairing with Arjhine on the eval-set review process changed how I think about data. She has a way of asking the question behind the question, and then measuring the answer.
Jose Ramirez
Staff ML Engineer, DataSpring Labs
Her undergraduate thesis was the first time a student brought me retrieval results with the failure analysis already attached. That instinct — results and limits together — has carried into everything she has built since.
