Pak Su Hyung

Over two months, Gyak worked on the Kernel360/F2-TECHPICK repository, delivering user-facing folder and bookmark management features with sharing, export, and tagging, while refining backend APIs and strengthening security. Using Java, Spring Boot, and TypeScript, Gyak established automated AWS deployment pipelines and improved CI/CD processes, enhancing release speed and reliability. The work included robust exception handling, request logging, and OpenAPI documentation upgrades to clarify authentication flows. Gyak also improved observability by introducing per-request UUID tracing and stabilized production logging. Additionally, a technical blog post on ordered data storage and a new content-curation API demonstrated both depth and practical engineering impact.
