Enterprise-Level RESTful API Implementation

Implemented a robust public RESTful API for an enterprise company, enhancing system integration and improving data synchronization across platforms.

Developed and maintained C# and PostgreSQL in .NET project, built on microservices using CQRS pattern

Implemented performant RESTful APIs for internal and external use to calculate data or perform events needed for the donation process in accordance with business rules

Optimized PostgreSQL queries to handle large amounts of data(billions of data points), along with using a lambda to populate new data every 30 minutes

Wrote C# scripts to backfill data for new features, allowing backwards compatibility

Utilized event bus to pass data between services, perform further logic in the donation workflow, track and rerun any events that got into the dead letter queue.

Refactored old services, with performance optimizations, added test coverage to services, along with creating test plans to ensure quality code and successful releases

Created new microservices for new features. Designed, documented, and implemented APIs and PostgreSQL schema to ensure the feature could meet business requirements
