November 2025, GreenCity: Delivered robust Excel export for rating statistics (covering both all data and filtered subsets) with improved data retrieval, pagination, and sorting; fixed 500 error during download; expanded test coverage and updated documentation. Completed maintenance and infrastructure improvements: code formatting cleanup, removal of unused imports, and LDM dependency updates moved to the global pom.xml to streamline dependency management. These efforts improved reporting reliability, reduced maintenance toil, and strengthened build consistency. Technologies demonstrated: Java, Maven-based build, test automation, and dependency management in a multi-repo setup. Business impact: reliable exports for stakeholder reporting, faster data access, and easier future upgrades.

August 2025 - ita-social-projects/GreenCity: Delivered two major areas: EcoNews Relevance and Embeddings Modernization, and Code Quality Improvements. Relevance calculations were moved to a Quartz-backed scheduled background job and OpenAI embeddings were integrated for article titles to improve relevance scoring, with AI-based relevance path removed. Added repository queries and batch processing for updating embeddings, and provided tests and documentation for embedding-related APIs. Code quality enhancements focused on readability and maintainability through documentation improvements, formatting cleanup, and removal of unused imports across modules.

July 2025 — GreenCity relevance system enhancements: Implemented an embedding-based Eco-news relevance data model with a new entity, converter, and repository; added automated scoring for eco-news on create/update via aspect-driven triggers. Introduced personalization and performance improvements using user likes, habits, coherence-based tagging, caching, and distribution of results across relevance pools, with utilities for weight normalization. Strengthened reliability with null-safety fixes in relevance calculations. Expanded test coverage and documentation for the relevance system and OpenAI integration. These workstreams collectively enhance relevance quality, reduce latency, and improve maintainability, driving higher engagement and scalable personalization.
