Recommendation for growth hackers for OSS project

Hope this question doesn't violate any guidelines.
We are looking for a freelancer growth hacker / community builder to help us drive genuine traffic and build awareness for a new OSS project we just released (https://github.com/datayoga-io/datayoga).
Any recommendations or pointers into where to look for freelancers or agencies? Our product is meant for data engineers so we need someone with at least basic tech background.
