Lauri Harjukoski developed two features for the MuViCo/MuViCo repository, focusing on both backend and frontend improvements. He implemented comprehensive authorization and validation testing for the presentations API using Node.js and Express.js, ensuring robust handling of unauthorized access, invalid IDs, and user-specific data retrieval. On the frontend, Lauri added a synchronized password visibility toggle to the Sign Up form in React, accompanied by unit tests to verify correct behavior. His work emphasized test-driven development and expanded test coverage for critical API and UI paths, strengthening security, data integrity, and reliability while streamlining the developer feedback loop through traceable commits.
