I contributed to the maintenance and evolution of Altabox, a digital document management system used by Corrugados Altavista for creating and managing carton and product proformas.

• Gathered and documented client requirements, analyzed system logic to identify necessary changes, and assessed their potential impact.
• Performed corrective and adaptive maintenance, implementing codebase changes to address critical requests and keep the system aligned with new business needs.
• Reviewed and updated unit tests to ensure software quality and system stability after each change.
• Client Communication: Collaborated closely with the client to clarify requirements and provide technical guidance throughout the change process.
• Documentation: Improved and updated technical documentation to facilitate future maintenance and onboarding of new developers.

Technology Stack: React and Bootstrap (frontend), Node.js (backend), and MySQL (database).

These contributions helped keep the system up to date, extend its useful life, and ensure it continued to support the client’s internal processes effectively.
