Side Projects
Hexschool Enterprise Project Mentor
2024/03 - 2024/07

I mentored a team of eleven students in HexSchool to create their web products over a four-month timeframe. To deliver the best outcome possible, I adopted the agile development approach that focused on short-term cycles for quick sprint completions. Before development began, I led the team in assessing technical and resource requirements. Next, I guided students to plan their progress based on set milestones. To boost teamwork and productivity, I held regular sprint review meetings for everyone to share the challenges they encountered and brainstorm possible solutions. I also asked students to examine their progress through sprint retrospectives. Throughout the process, I emphasized honest expression of one’s situation and appreciation of others' support. This way, I forged a coherent and supportive team, in which everyone felt confident and comfortable in contributing their strengths and helping others in overcoming difficulties.
