Graph theory
2013年にNeo4j Graph Databaseに出会ってからグラフ理論の良さを伝えるために活動しています。
Apple IIの世界に魅せられてからソフトウェアの世界で活動しています。 たくさんの異なる分野のクライアントで新しい事を学ぶことは非常に面白いですね。 最後にはクライアントの社員よりも詳しくなったりします。 40年以上もこの業界にいると多くの変化を目の当たりにしていますが、いつになってもこの世界は面白いです。
2009年からスクラム開発、2013年からNeo4jグラフデータベースに関わっています。 どちらも今まで悩んでいた問題があっという間に解決してしまったので今までの苦労は一体何だったのかと思うくらいです。 さらに共通するのは理論で知っているだけではダメで、体験すると行動が明確に変わる事でしょうか。
これからも新しい手法や技術が出てくると思います。 変化しないで続けることと変化して対応することはどちらも重要なので良いバランスでやりたいですね。
