During March 2025, contributed to the Jfranbm04/racehub repository by developing a user profile management feature focused on security and flexibility. Implemented partial updates in the UserController, allowing individual fields such as name, email, roles, banned status, age, gender, and image to be updated with granular validation. Enhanced the password change process by requiring old password verification, enforcing validation rules, and securely hashing new passwords. Updated environment configuration to support dynamic database port selection via the .env file, improving deployment adaptability. The work leveraged PHP and environment configuration skills, emphasizing robust API and backend development practices to improve data integrity.
