Jesus Santos developed a scalable baseline platform for the Proyecto-Final repository, focusing on modular architecture, robust error handling, and enhanced observability. He established core backend capabilities using Java, Spring Boot, and MyBatis, integrating MapStruct for DTO mapping and Log4j for logging. His work included designing a rules engine for business logic, implementing denial rules with validation pipelines, and ensuring reliable database connectivity. By refactoring project structure and standardizing naming conventions, he improved maintainability and onboarding. Comprehensive API documentation and test scaffolding were added, resulting in a production-ready foundation that accelerates feature delivery while reducing risk and supporting future growth.
April 2025 – Proyecto-Final performance summary: Delivered a scalable baseline platform with enhanced observability, robust error handling, and a modular rules engine, enabling faster, safer delivery of business capabilities. Key features delivered: - Baseline architecture and scaffolding with POM refactor for MyBatis and folder naming alignment (commits: 9dbb068..., f06c1d16..., be6eebdf..., 1c61b9e8..., 077cf492..., a3d201be...). - Documentation updates including README and agreement document to align on expectations and rules for collaboration (commits: c6a478f9..., 75cf423f3...). - Observability and API exposure: log4j integration, dependency configuration, DefaultRollingStrategy, and Swagger API docs (commits: 33099834..., 502adebf..., 3ffc6356...). - Exception handling framework: addition of an exception tree structure and NullValueException, enabling consistent error reporting (commits: 58279e81..., f1787963...). - Denial rules and rules engine: Rules Context DTO, mapper and interface; Denial Rule for scoring thresholds; DebtAmountLessThanMonthlyQuote; tests scaffolding (selected commits across 00506d5..., a411756..., 22154064..., d94384ad...). - Requests core domain: Custom InvalidRequestDtoException, RequestController templates, mappers, services, global exception handling; RequestMapper fixed for remote DB; MapStruct updates for Request and related entities (selected commits: 5c014894..., e62f1b9a..., bc92dccd..., 65f003e6..., f3767dca..., ea3a4e60...). - Data mapping and refactors: MapStruct-based Debt mapping; Client suggestion MapStruct refactor; naming rules refactor; cleanup for main class; PR-driven consistency improvements (commits: 89785904..., 18487b53..., 840a90ff..., 8574c3de...). Major bugs fixed: - Remote DB connectivity for MyBatis RequestMapper fixed (e82e0f8e...). - Denial Rules validators and validation path fixes (6ba60061..., 0cef5687..., 60d6262c..., f54b0aed...). - Main class cleanup as part of project slimming (8574c3de...). Overall impact and accomplishments: - Established a solid baseline architecture and cross-cutting concerns (observability, APIs, error handling) that reduce risk for new features and accelerate delivery. - Improved maintainability through standardization (naming, PR-driven consistency) and enhanced test coverage for critical denial rules. - Improved system reliability in production readiness with remote DB connectivity fixes and robust exception handling. Technologies/skills demonstrated: - Java, Maven-based project management, MyBatis integration, MapStruct-based mapping, Log4j, Swagger, and comprehensive exception handling patterns. - DTOs and mapper design, validation pipelines, and test scaffolding for rules-based decisioning. - Documentation discipline (README and agreements) to align expectations and reduce onboarding time.
