# Dapp developers
Decentralized application (dApp) developers rely on data pipelines to build applications. The **Hemera Indexer** is designed to streamline this process by enabling parallel execution of **User-Defined Functions (UDFs)** alongside the core indexing tasks.
By running the Hemera Indexer, developers can utilize the power of ACI (Account-Centric Indexing) to efficiently organize blockchain data by deploying custom UDFs to extract, transform, and analyze data tailored to their specific use cases.
This parallel architecture not only optimizes performance but also simplifies complex data workflows, empowering developers to focus on building next-generation Web3 applications.
