2. akkey • CEO @AkkeyLab, Inc. • Engineer @pixiv Inc. • DroidKaigi Staff • try! Swift Tokyo Organizer
3. 私とDroidKaigi
4. 私とDroidKaigi 4年連続セッション応募
5. 私とDroidKaigi Google I/O Extended Tokyo 2025
6. 私とDroidKaigi Galaxy XR求めて韓国へ • 発売日に行ったが買えずに帰国 • 開発は継続
7. DroidKaigi 2026
8. VMSの開発
9. VMSの開発 Video Management System • 収録映像のリアルタイム確認 • 進行状況の確認 • 確認作業を遠隔で実施可能
10. VMSの開発 Appleの技術を活用 • Metal API で描画 • Apple Container で検証
