Santiago Firpo developed and enhanced core backend and API infrastructure for the pucrs-constrsw-2025-1/base and ConexaoTreinamento/conexao-treinamento repositories, focusing on modularity, security, and developer experience. He refactored domain models, enabled OAuth and UMA-based authorization, and unified API client logic using Java, TypeScript, and Spring Boot. Santiago improved deployment reliability through Docker Compose, streamlined onboarding with updated submodules and configuration management, and strengthened CORS and Swagger integration for frontend-backend compatibility. His work addressed both feature delivery and bug resolution, demonstrating depth in backend development, API integration, and configuration, resulting in more maintainable, secure, and developer-friendly systems.
October 2025: Key features and fixes delivered for ConexaoTreinamento/conexao-treinamento include a centralized apiClient to standardize data fetching and mutations across components, enabling a cleaner API interaction layer and easier maintenance; a CORS fix enabling the Vercel-hosted frontend to communicate with the backend; and a local DB_URL fallback to connect to a local PostgreSQL instance during development. These changes reduce API integration complexity, improve developer experience, and support consistent deployments. Technologies demonstrated include API client refactor, CORS configuration, and environment-based connectivity.

April 2025 monthly summary for pucrs-constrsw-2025-1/base: Delivered essential OAuth platform work and dev-infra improvements that increase reliability, security, and developer productivity across environments. Core enhancements for OAuth configuration via environment variables, including service URL and external port handling, reduce misconfigurations and enable consistent runtime behavior. Major stability fixes were implemented for OAuth healthcheck and Spring client, decreasing production risk. Expanded the OAuth client ecosystem with TypeScript packaging info, client fixes, and a more robust example using Promise.allSettled. Development and deployment workflows were improved through dev infra updates (docker-compose debug overrides and hygiene ignore rules), ongoing OpenFeign integration groundwork (OAuth wrapper rename and prep for Spring OpenFeign client), and additional deployment/Docs improvements (separate docker-compose override for non-external volumes and updated OAuth docs).
