Expense Manager – Secure Spring Boot Service with DevSecOps Pipeline

Expense Manager is a secure, enterprise-grade financial management application developed using Spring Boot and modern DevSecOps practices. The project demonstrates how secure software development, automated compliance, and continuous delivery can be seamlessly integrated into a production-ready backend application. Built with Spring Boot, Spring Security, PostgreSQL, and Docker, the application implements robust authentication, role-based authorization, CSRF protection, and secure database interactions aligned with OWASP security recommendations. The backend architecture follows clean layering principles to ensure maintainability, scalability, and long-term extensibility. A comprehensive six-stage DevSecOps pipeline automates secret scanning, dependency vulnerability analysis, container security validation, static application security testing (SAST), dynamic security testing (DAST), and container image signing before deployment. Every code change is validated through automated testing and security verification, ensuring only production-ready builds progress through the release pipeline. This project demonstrates practical expertise in secure backend engineering, cloud-native deployment workflows, and automated security governance, reflecting modern enterprise software development standards.
