Elasticsearch, Java/Kotlin, misc. backend stuff I've used in the past 2 decades. Reluctant devops.

Rust, Kotlin, Ethereum, graph databases.

Inbot; doing an ICO. Also check my Github (jillesvangurp). I try to OSS commodity stuff that I don't want to reinvent in future projects.

Generally approachable to talk tech and I enjoy interacting on on forums, twitter, meetups, etc. If you are a recruiter: this was not an invitation.
