Denis Dzenskevich
Worked on the epam/Indigo-ELN-v.-2.0 repository, focusing on backend development, infrastructure automation, and data reliability over five months. Delivered a CloudFormation-based deployment pipeline using AWS services such as EC2, S3, and CodeBuild to enable repeatable CI/CD workflows. Refactored the data access layer with Spring Data MongoDB and Java, improving maintainability and onboarding. Enhanced database schema and workflow for compound registration and search, leveraging PostgreSQL and SQL scripting. Stabilized local development with Docker, Maven caching, and Nginx configuration, and addressed file attachment consistency using BSON utilities. The work emphasized automation, code clarity, and robust data management across environments.

Jul 1, 2025July 2025 monthly summary focused on data integrity and stabilization of file attachments in Indigo-ELN. Implemented standardized BSON handling using BsonUtil to store and retrieve file IDs as strings across file saving, temporary file cleanup, and DTO creation. This fix eliminates inconsistencies in file identifiers and reduces attachment-related errors.
