Datachain, Inc. / Blockchain Developer
I have passions to work on something social issues especially environmental issue. These days I heard a term `Green Tech` which focuses on that. However there seems not to be popular and general in Japan's tech field because of low profitability. Blockchain made me expected something promising and I tried to learn it through development of crypto currency exchange platform. Unfortunately such crypto currency is merely used for investments and energy efficiency to make transactions so called mining was terrible. It means current blockchain technologies are harmful on environment. That fact made me disappointed. IMO more breakthrough would be needed. For now I'm working on Ad-tech field because it requires highly skilled engineer and I'm satisfied with working environment because of skilled and smart colleagues. I had worked in Europe as Golang developer. My favorite technologies are Golang, Microservice Architecture on cloud native environment. I worked(ing) for - Dutch startup company developing events management system as Full-Stack Engineer - Luxembourg fin-tech company developing assets management service as Full-Stack Engineer - International (HQ:Netherlands) travel company developing booking accommodation service as mainly Golang Developer 転職活動中なのでお声がけ頂けると嬉しいです(2021/03)
