CTO + Cofounder at Ambra
Ambra is an intelligent and autonomous RCM platform built exclusively for EMS, we specialize in denials management and clean claims submission. By automating the revenue cycle from scrubbing to submission, Ambra helps agencies recover more of what they've earned, and quicker (cut AR days down to 3 days), and as a bonus, comes paired with a voice-first scribe that cuts PCR time down to under 3 minutes and auto-submits claims for you on the same day.
If you'd want to try this out for your agency, please email us at founders@ambra911.com
I'm based in San Francisco / San Jose (and a fan of the Warriors 馃寜 + Sharks 馃)

Research
Security, privacy, and formal methods in healthcare systems.
EmberDB - FHIR-native time-series storage for critical care. A specialized database treating FHIR Observations as first-class citizens, benchmarked against InfluxDB, TimescaleDB, and QuestDB on MIMIC-III data.
Healthcare Voice Agent Security - Evaluating AI voice platforms deployed in healthcare settings, covering prompt injection, PHI extraction, and synthetic voice attacks with a novel FHIR-compliant testing framework.
Privacy-Preserving Healthcare Cost Prediction - Custom secure multiparty computation protocol enabling joint model training across hospitals, insurers, and public health agencies without exposing raw data.
zkDNA - Zero-knowledge proofs for negative STR DNA match verification, allowing proof of non-match in forensic contexts without revealing actual genetic data.
Formal Verification of FHIR Resources - Applying lightweight formal methods (Alloy) to verify structural integrity and safety invariants of HL7 FHIR data models.
