Worked on the TEHIK-EE/tedi-design-system repository, focusing exclusively on improving UI stability and build reliability during April 2025. Addressed a critical webpack serialization issue by standardizing alignment properties in SCSS, specifically replacing 'align-items: start' with 'align-items: flex-start' across multiple files. This targeted CSS and SCSS fix resolved layout inconsistencies and reduced runtime errors, directly linking the solution to a reported issue for clear traceability. No new features were introduced, as all efforts centered on enhancing maintainability and ensuring consistent component behavior. Demonstrated a methodical approach to front end development, prioritizing quality and long-term stability over feature delivery.
