PROFILE
Christopher Lyko
Worked on the jst-seminar-rostlab-tum/personio-foundation-coachai repository, delivering core frontend and backend enhancements over three months. Developed real-time simulation features using React, TypeScript, and WebRTC, including a user-facing microphone toggle and a mock RTC connection for testing audio streaming between peers. Improved code quality and developer experience by consolidating tooling with ESLint, Prettier, and Husky, and streamlined CI/CD processes. Integrated Sentry tracing and monitoring across both frontend and backend, enabling unified error tracking and performance monitoring. These efforts enhanced reliability, reduced onboarding time, and provided comprehensive observability, supporting faster incident response and more robust production deployments.

Jun 1, 2025June 2025 monthly summary for the jst-seminar-rostlab-tum/personio-foundation-coachai repo: Delivered a user-facing Microphone Toggle on the Simulation Page with WebRTC integration, enabling mute/unmute during simulations. Updated the simulation footer and UI to reflect microphone state, and implemented enabling/disabling of audio tracks. Performed minor cleanup of console logs and refined state handling to improve reliability during live sessions. No critical defects reported; focus remained on feature delivery and code hygiene to drive user control and reduce support friction.
