PROFILE
Lucas Eduardo De Souza Silva
Over three months, contributed to the SQLutions-FATEC/API-3-Semestre-Backend repository by designing and implementing a scalable HR and contracts data model, introducing DTO-driven REST APIs, and enhancing data integrity through robust entity relationships and soft delete mechanisms. Leveraged Java, Spring Boot, and Hibernate to deliver features such as employee photo management, analytics-ready reporting views, and active record lifecycle controls. Refactored repositories and services for maintainability, introduced pagination and automatic filtering for active records, and improved data quality with precise timestamping and seed data updates. These efforts enabled accurate analytics, streamlined HR workflows, and ensured consistent, maintainable backend architecture.

May 1, 2025May 2025 delivered analytics enhancements and robust data lifecycle controls that drive accurate metrics and scalable data access. Implemented an AnalyticsSummary entity and the analytics_summary read-only view with automatic startup initialization and precise timestamps using LocalDateTime. Introduced soft delete across core entities (Company, Employee, Contract) with deletedAt, auto-filtered active records, and pagination for company queries, ensuring data integrity and efficient queries. Benefited from a series of repository/service refactors, data script updates, and cleanup that reduce duplication and improve maintainability. Overall, the month improved reporting accuracy, data quality, and system readiness for analytics-driven decisions, while demonstrating strong Java/Spring, Hibernate, and data-layer skills.

Apr 1, 2025April 2025 monthly summary for SQLutions-FATEC/API-3-Semestre-Backend: Key features delivered include the Employee-Company relation (via company_id and ManyToOne), a full employee photo management suite (Photo entity, storage/retrieval endpoints, and cache control), and Active Records lifecycle for employees and companies (soft delete, active filters, and relevant endpoints). Seed data for companies with deleted=false was added; Company model now includes a default deleted flag and soft-delete refactor. Major maintenance tasks include refactoring the soft-delete entity for Company and aligning service structure. Critical bugs resolved: corrected Employee attribute, fixed createEmployee key, and removed a duplicated FK between Employee and Company. These changes collectively improve data integrity, enable accurate lifecycle management, and deliver business-ready capabilities for HR workflows (employee photos, active records, and company status).

Mar 1, 2025March 2025 monthly summary for SQLutions-FATEC/API-3-Semestre-Backend. Delivered a scalable HR and contracts core data model, a DTO-driven Employee API, and improved clock-in data mapping, with targeted formatting cleanups. These efforts enhance data integrity, consistency, and maintainability, enabling faster business feature delivery and clearer domain boundaries. Key features include a five-entity HR/Contracts model (Funcionario, Movimentacao, Empresa, Cargo, Contrato) with baseline schemas and initial relationships; a DTO-based Employee API with EmployeeDTO and updated controller/service logic; and clock-in DTO mapping enhancements with robust create/update handling and better error reporting. Supporting formatting fixes (per-file line additions and name-column tagging) improve code quality and maintainability.
