Senior Software Engineer Apr 2024 - Present

• Architected a production multi-agent AI platform on Azure Kubernetes Service orchestrating specialized agents using Google’s Agent-to-

Agent (A2A) protocol and Microsoft Agent Framework, with Model Context Protocol (MCP) for self-discovered Snowflake queries, Redis-

backed distributed circuit breakers across 1 to 50 pod autoscaling, and a React 19 + MUI frontend.

• Shipped full-stack RAG search platform used by 5,000+ users across Providence: React frontend with custom SSE streaming, orphan recovery,

and multi-layer prefetch caching; async FastAPI backend with SQLAlchemy and role-gated SQL builder over 12+ filter dimensions; rebuilt

LlamaIndex RAG retrieval underneath, cutting query latency 47s to 4-5s via three-path retrieval routing, time-to-first-token 15s to 3s via async parallelization and SSE streaming, and sparse search 63s to 1-5s by fixing stop-words and stemming bugs.

• Owned a high-priority tracking initiative serving 4,000+ users across 54 sites, building a config-driven registry platform that generated schemas, data transformations, UI configuration, and Airflow pipelines from spec-driven definitions.

Software Engineer Aug 2022 - Mar 2024

• Led migration from Datadog to self-hosted telemetry stack for internal .NET services: built NuGet middleware injecting correlation IDs and standardizing logs (ELK), metrics (Telegraf sidecar to InfluxDB), and traces (Jaeger) over OpenTelemetry; built Grafana dashboards across all three signals; eliminated per-host vendor pricing and enabled multi-year retention, migrating 4 production services.
• Built mobile features and CI/CD infrastructure for Praia Health, a Providence-incubated patient engagement platform serving 800,000+

monthly active users that later spun out and raised a $20M Series A, across SwiftUI feature development, Bitrise pipeline setup, and Appium-

based test automation.
