• Greenfield Framework Design: Spearheaded the "from-scratch" architectural design of a generic, metadata-driven ingestion orchestrator supporting dynamic schema evolution to automatically handle upstream data drift from Pricing, Vendor, and AI4Ops systems into Snowflake. • Modular Enterprise Reusability: Engineered an enterprise-grade core library published to Artifactory, establishing a "Write Once, Run Anywhere" standard for ingestion that serves both the Ops Data and Shared Data platforms. • Multi-tenant Security & Compliance: Architected a secure, multi-tenant framework incorporating automated PII/Sensitive data masking and tenant isolation, ensuring strict regulatory compliance and data privacy for sensitive financial datasets. • Resilient Data Orchestration: Integrated self-healing logic and automated retry mechanisms with exponential backoff into the core library, reducing manual intervention for S3-to-Snowflake ingestion failures by 90%. • Metadata-Driven Automation: Designed a configuration-first engine that automates complex data staging via one-time metadata setup, enabling rapid onboarding of new use cases for management reporting and baseline workflows. • Omnichannel Data Delivery: Architected a versatile egress layer exposing processed datasets via REST APIs, Snowflake Views, and S3, ensuring high-availability and low-latency access for diverse downstream consumers. • Observability & Operational Excellence: Implemented a proactive monitoring strategy using Splunk and AppDynamics for real-time alerting and dashboarding, ensuring 99.9% uptime for mission-critical data pipelines.
