Experienced Software Engineer

I am an experienced software engineer, with decades of experience over multiple stacks, operation systems and technologies. My primary focus lately has been distributed data processing pipelines and distributed network APIs. I have also been working with linked data, graph databases and blockchains/cryptocurrencies lately. Looking for a position of Senior Software Engineer/Software Architect/Tech Lead or equivalent. I like learning new things and new challenges, and creating systems from design to implementation and maintenance stages, so if your current stack does not match my experience but you think you could use a good experienced backend engineer, please don't hesitate to contact me.
