ElasticSearch Financial Data Index

DynamoDB Streams to search-optimized query layer

ElasticSearch index with DynamoDB Streams pipeline and .NET Core API for near-real-time portfolio and account queries.

Context

Built ElasticSearch index backed by DynamoDB Streams and PostgreSQL sync, exposed via .NET Core API with auto-refresh and stale-data cleanup — powering Blazor WASM UI and third-party platform consumers.

What I built

Implemented change-data-capture from DynamoDB Streams to ElasticSearch, PostgreSQL field sync, .NET Core search API, and Blazor WASM integration with freshness monitoring.

What it shows

Data pipeline engineering for query performance at scale — from change capture through search index to consumer API.
