– Designed and developed a modular ERP platform built on a microservices architecture, delivering a modern, scalable, and resilient enterprise system. – Implemented secure authentication with Keycloak and a dedicated authorization service, providing two-level access control (API and data) for fine-grained permission management. – Enhanced auditability through detailed logging of business flows and user actions. – Developed a notification system (Kafka, WebSocket, Email, SMS) to improve communication efficiency and reduce service interruptions. – Improved monitoring and incident resolution using Prometheus, Grafana, Tempo, and Loki, providing real-time alerts and performance tracking.

– During this internship, I participated in the design and development of a comprehensive occupational health management application. The goal was to streamline employee tracking and manage medical data while ensuring data security and confidentiality. – The application includes several key modules: Medical Records: Complete management of employee medical records, ensuring confidentiality and compliance with applicable regulations. Risk Post Management: Classification of work positions based on associated risks and definition of specific medical tests and periodic checks for each position. Medical Check-ups: Tracking medical examinations for new employees and periodic check-ups according to legal requirements and risk-related positions. Consultation and Intervention Tracking: Recording consultations, diagnoses, prescribed treatments, and maintaining a full medical history. Evacuation Tracking: Recording and monitoring evacuations across different work sites. – Technologies and tools used: Back-end: Java Spring Boot Front-end: Angular Database: PostgreSQL Security: Keycloak for user and role management Deployment: Docker images on AWS

– Gained practical knowledge in Oracle database administration. I learned to manage users, permissions, data backup and recovery, as well as database maintenance and performance optimization. – This experience allowed me to understand the inner workings of DBMS and best practices for ensuring data security and availability.

– Implementation of authentication and role management using Keycloak to secure the application. – Design and development of a complete invoicing application, including management of clients, products, and invoices, with a modern interface and an architecture following best practices in web development.
