Over four months, Daniel contributed to the IntersectMBO/cc-ballot repository by building and enhancing backend services for blockchain-based voting workflows. He developed RESTful APIs and CLI tools using Java, Kotlin, and Spring Boot, focusing on candidate management, voting, and integration with Cardano blockchain services like Koios and Blockfrost. Daniel implemented robust error handling, multi-database support with PostgreSQL and H2, and improved data modeling for draft workflows and voting receipts. His work addressed both feature delivery and system reliability, with careful attention to API standardization, authentication, and exception handling, resulting in a stable, extensible backend supporting complex election processes.
