I joined early and helped take a multi-tenant healthcare SaaS from first commits to a system clinics depend on. Most of my time went to two hard edges: syncing patient records across Epic, Cerner, and ModMed without letting tenants bleed into each other, and standing up a voice-agent layer on Retell AI that answers in under a second using retrieval through Pinecone. The compliance work was part of shipping, not a phase bolted on afterward.

• EMR sync across three vendor systems — Epic, Cerner, ModMed
• Sub-1s voice agent on Retell AI with Pinecone retrieval
• HIPAA hardening: PHI redaction, OAuth 2.0, role-based access, audit logging

Role 1

I built research-facing web apps — collection and analysis tools on React, TypeScript, Vite, and Firebase — for teams working with large text datasets. That included the NLP pipelines and LLM-backed features they needed to make sense of the corpora as they grew.

Role 2

I owned backend APIs for a car-inspection booking system running more than 500 appointments a day. Alongside feature work I cleared over 20 critical issues, and a focused refactor of the legacy backend brought a 15% performance gain.

• REST APIs sustaining 500+ daily bookings
• 20+ critical backend issues resolved
• 15% performance gain from a legacy refactor

Role 3

I built DAOChatbot end to end — a retrieval-augmented query system on Flask, React, MongoDB, and Pinecone — and owned Gender-DEI Bot, a DistilBERT bias-detection platform. On the latter I cut inference latency by 60%.
