• 7+ years experience building and maintaining  Python microservices and  Flask‑based REST APIs for data orchestration, ingestion, and integration with downstream systems.
• Experience with implementing authentication, authorization, error handling, and logging within APIs and services.
• 7+ years experience developing optimized PostgreSQL schemas, stored procedures, and performance‑tuned queries to support analytics and regulatory reporting.
• 5+ years experience engineering Power BI reporting layers, semantic models, DAX measures, and high‑performance datasets for enterprise risk dashboards and regulatory reporting.

Desired Skills:

• Ability to ensure data accuracy, perform validation and reconciliation, and resolve complex reporting and refresh pipeline issues.
• Experience leveraging AI tools (Copilot, Claude, Foundry) to accelerate development, automate code generation, enhance documentation, and support AI‑assisted analysis and testing.
• Experience integrating  CI/CD pipelines for automated build, test, and deployment.
