About

Full-stack/backend engineer with healthcare and enterprise experience: built and secured AWS-hosted services for a clinical EHR product that redacts/transforms hospital patient records for pharma customers (e.g., AstraZeneca, Johnson & Johnson). At Cisco, led an incremental Ruby-to-Python/Django migration for a compliance backend, and has deep multi-tenant security experience using Postgres RLS tied to JWT plus DLQ patterns to harden data pipelines.

Key Strengths

• Designed scalable, security-focused backend for clinical EHR data sharing
• Strong AWS deployment and infrastructure automation (ECS, Copilot, CI/CD with GitHub Actions)
• API design with validation and security controls (Pydantic models, auth, middleware, rate limiting)
• Led incremental Ruby-to-Python/Django migration with data consistency between MongoDB and RDS and minimal customer disruption
• Implemented Postgres RLS tied to JWT claims for multi-tenant isolation at the database layer
• Improved robustness by identifying poison-pill ingestion failures and adding DLQ-based quarantine to prevent worker queue crashes
