Project Context: Tunav Smart Circuit Breaker – Development of a cloud IoT platform for centralized monitoring and real-time tracking of industrial circuit breakers (Clients: Sagemcom, TLScontact, PGS Group, Pharmaservice). Development of the application backend in Java / Spring Boot: design of secure REST APIs, MQTT integration, and PostgreSQL performance optimization (+20%).

• Contribution to the backend architecture and scaling of a platform monitoring over 1000 real-time devices.

• Implementation and improvement of CI/CD pipelines (Docker, Jenkins, GitHub Actions, SonarQube), reducing deployment incidents by 40%.

• Participation in Agile/Scrum rituals: planning, code reviews, testing, and continuous improvement.

• Occasional frontend contributions in Vue.js for dashboard development and data visualization.

COLLINE - International collateral management platform developed by VERMEG group, used by major investment banks (RBC, CIBC, State Street, Société Générale, HSBC, Wells Fargo, Lloyds Bank) to centralize and optimize collateral management processes.

• Refactoring and evolution of the Java / Spring Boot backend, migrating from a monolithic architecture to microservices, improving performance and scalability of over 2,000 REST APIs.

• Development and optimization of critical business features, including a batch booking module, reducing processing times by 70%.

• Implementation of new backend features following best development practices, including unit tests and technical documentation, reducing technical debt by 80%.

• Contribution to a crisis management project (March 2022): fixing over 80% of priority anomalies within critical deadlines for a strategic client.

• Improvement and reliability of CI/CD pipelines (Jenkins, GitLab, SonarQube, Maven), significantly reducing production deployment incidents.

• Participation in workshops and Agile/Scrum within a team of 5 developers.

• Participation in the technical design of an IoT monitoring solution within an Agile/Scrum team.

• Development of backend services and REST APIs for real-time management and updating of IoT data.

• Integration of web interfaces for visualization of connected devices.

• Optimization of application performance and participation in testing and debugging phases.

• Contribution to Agile rituals, code reviews, and technical documentation. Technical Environment: Backend: Node.js, REST APIs | Database: MongoDB | Tools: Git, JIRA
