Sharing our DX improvement journey from scattered environment variables across GitHub Secrets, Google Sheets, and Key Vault to establishing a SSOT with an internal CLI tool.

A retrospective of the DND hackathon: from pitching ideas and team building to development and the presentation. It captures frontend work, collaboration with designers, using the Kakao Map SDK, and implementing OAuth.

A retrospective on the Microsoft-hosted public sector innovation hackathon: building an abusive-complaint filtering service with generative AI and Azure OpenAI, making an MVP with LangChain.js and FastAPI, and reaching the finals.

A mentoring experience at Goormthon Univ Cherry Blossom: helping hackathon mentees with diverse questions, supporting frontend-focused issues, and reflecting on growth and renewed motivation as a developer.

This post is based on my experience participating in Goormthon 9th. I wrote about why I joined the Jeju hackathon, the 4-day schedule, team building, project development, mentoring, and more. It covers collaboration with people from various roles, the outcomes, and the romance of hackathons. I recommend it to anyone considering joining, and I share the lessons I learned and what I wish had been better.
