In February 2025, Helo worked on the HoiskolensChemikerforening/hc-backend repository, focusing on frontend development to improve UI reliability. Helo addressed a structural issue in the pagination component of index_sportskom.html by properly closing an unclosed div tag, which had caused rendering inconsistencies and UI glitches. Using HTML and frontend debugging skills, Helo ensured that the pagination displayed correctly across different pages, supporting a smoother user experience. The work involved targeted code changes and careful verification rather than broad feature development, reflecting a focused approach to maintaining code quality and addressing specific bugs within the existing frontend architecture.
