PROFESSIONAL EXPERIENCE

Middle .NET Software Developer / Scrum Master responsibilities Jan 2025 – June 2026
Phreesia
Secure medical platform managing patient data, automated document processing, and integrations with
external healthcare providers. Owned backend integration work including ML service integration,
designed REST contracts, and supported the Angular front-end.
• Designed and built integration modules from the ground up, including REST API contracts for data
exchange with external healthcare providers and automated document processing pipelines for
extraction of structured data from unstructured medical documents.
• Developed and maintained backend services in C#/.NET and ASP.NET Core Web API; extended existing
service methods with backwards-compatible changes to protect downstream consumers.
• Integrated NLP capabilities for parsing clinical notes and patient records, enabling intelligent data
routing and automated classification of medical documents.
• Implemented a retry mechanism for external calls and resolved concurrency issues around
incremented counters, reducing transient integration failures from ~15/day to near zero.
• Tightened the pre-release QA process by requiring regression on the test environment for every story
— including small changes — before merging to the release branch, eliminating regression escapes
from “minor” fixes.
• Built reusable Angular components for document upload workflows and implemented real-time
status tracking via SignalR for long-running processing tasks.
 • Configured and maintained Terraform modules for integration infrastructure — provisioning API
gateways, networking resources, and external service connections to ensure consistent and
reproducible environments across dev/test/prod.
• Ran Scrum Master activities: facilitated daily stand-ups and sprint planning, maintained
Jira/Confluence documentation, and coordinated priorities and task distribution.
