Feb 1, 2025February 2025 monthly summary for Quant-NTU/persistence-middleware: Reintroduced and exposed REST API for transformed crypto operations. Restored the REST controller with Spring annotations and mappings to enable external access at /crypto/transformed. This work was delivered through two commits (aaaf137da38eaf54904783c0fbd26ea27fbf3770 and ed5f110389b4a4380199d4cfbdcbd22a31b665cd). Business value: enables external integrations, improves API discoverability and sets a foundation for future enhancements. Technical achievements: REST controller restoration, Spring annotations, endpoint mappings, improved modularity. No major bugs fixed this month; focus was on API surface restoration and integration readiness.

Nov 1, 2024Month: 2024-11 | Summary for Quant-NTU/persistence-middleware Key features delivered: - TimescaleDB/JPA integration scaffolding: refactored repository structure to explicitly separate JPA and MongoDB repositories, updated application.properties, and added TimescaleDB/JPA dependencies for scalable time-series storage. - TransformedCrypto data API: implemented data model, REST controller, service, and repository with endpoints to query by symbol, currency, and timestamp range. - Testing framework and unit tests: integrated Mockito and Kotlin testing libraries; added unit tests for TransformedCryptoController and TransformedCryptoService. Major bugs fixed: - Resolved cross-store repository wiring issues by isolating JPA and MongoDB packages, preventing misrouting of data-store operations and stabilizing configuration. Overall impact and accomplishments: - Enables scalable time-series analytics for transformed crypto data with reliable, test-covered code and explicit multi-store architecture, reducing risk and accelerating feature delivery. Technologies/skills demonstrated: - Java/Spring Boot, JPA/Hibernate, TimescaleDB, PostgreSQL driver, Gradle configuration - REST API design and data modeling for time-series data - Unit testing with Mockito and Kotlin test libraries
