Aboutme
I'm Hisatomo Futahashi. I work primarily as an SRE, specializing in AWS / Datadog / FinOps / Security.
My favorite sayings are "Persistence is power", "Patience and perseverance overcome all things", "Fortune comes to the homes of those who smile", and "A heart of love and compassion". Passion and conviction in work, respect and trust with people, laughter as the default mode. Probably.
My strengths come from execution skills built on large-scale projects at major Japanese corporations, technical and collaboration skills cultivated at globally expanding startups, and a wide range of accumulated SRE experience.
