I lead both frontend and backend engineering efforts, architecting solutions that turn clinical workflows into reliable software used in real-world care settings. • AI-Powered Content Systems: Played a key role in building and maintaining a content generation system for automated creation of treatment protocols and therapist training materials using structured templates, schema-validated pipelines, and multi-stage content orchestration. • Full-Stack Development & Ownership: Primary engineer responsible for building and maintaining TypeScript/Next.js monorepo powering multiple apps, including Care (a patient-facing interface delivering personalized treatment pathways and interactive activities like breathing exercises and journaling) and Studio (a dual-purpose therapist platform with practice management and clinical content authoring). • Backend & Data Platform: Designed and supported backend services (TypeScript NestJS with GraphQL), PostgreSQL schema design, business logic via custom mutations and triggers, and robust security via row-level security and role-based access control. • Mobile App Delivery: Delivered a mobile-first patient experience by wrapping our web application in a React Native container, enabling native-like UX and successfully shipping to both iOS and Android app stores. • Cross-Functional Collaboration: Worked closely with product, design, and clinical teams to translate domain requirements into technical solutions that improve therapist efficiency and patient engagement. I’m passionate about engineering systems that solve real problems — leveraging modern web technologies and emerging AI techniques to improve access, quality, and sustainability of healthcare. ### Principal Engineer @ Frontera Labs Jan 2023 – Jan 2024 | Santa Barbara, CA RealtyAI | 2023 AI-powered CRM Integration tools for Realtors Created Generative AI tooling on Real Estate software, utilizing langchain/langraph to create a RAG pipeline, pgvector for similarity matching, and Promptfoo for vulnerability testing BonfireAI | 2023 AI-powered customer engagement platform Created a React chrome extension that integrates OpenAI tools into the existing Gmail interface.
