Patrick Perez developed the Biotech_Lab_System, delivering a robust cloud-backed inventory and user management platform with end-to-end authentication and secure data flows. He architected both backend and frontend scaffolding, integrating Java Spring Boot and Flutter to enable cross-platform access and seamless CRUD operations. Patrick implemented API security, JWT authentication, and containerized deployments using Docker, ensuring reliable CI/CD and reproducible builds. His work included transactional integrity for inventory and purchase orders, file attachment support, and persistent data synchronization. By stabilizing the database schema and refining entity models, Patrick improved auditability and deployment safety, demonstrating depth in backend development and system reliability.

October 2025: Core persistence stabilization delivered for Patthethicc/Biotech_Lab_System with a focus on reducing schema drift, improving auditability, and tightening data integrity. Key changes include disabling automatic database schema updates, enforcing GenerationType.IDENTITY for Brand, User, and Inventory IDs, removing the CombinedTrnPO entity, and refactoring PurchaseOrder to include brandId, addedBy, and dateTimeAdded. These changes reduce deployment risk and provide clearer auditing trails.
