# Intro call with Evgenii Zakharov

> A 30-minute video call to see whether we fit: a role on your team, a contract, or an architecture review. Tell me a little about it in the form, so I come prepared and can say early if it isn't something I can help with. If none of the times work for your time zone, write to to@risen.dev and we'll find one.
