John Z Black

John has been a big help all summer on internal Praxent tools while pinch hitting across our portfolio by bridging emerging technical gaps between clients. Without his expert creativity and quick work, we could have dropped the ball on a number of our client accounts. John's very creative and impressive work on Praxent's market research tools blew me and Kevin away and have helped us to acquire and maintain a clearer view of the competitive landscape. Thank you John for all you do to support our clients and teams with your creativity and "yes and" spirit.

Tim Hamilton — Founder and CEO — Praxent

John has done some outstanding work on SCI. He developed a robust backend platform, deployed on AWS with a microservice architecture that leverages serverless technology, and serves React via S3. This solution was built in such a way to scale as needed, reducing overall cost. In addition, John was able to build the solution in such a way that we could reuse this technology and strategy in future clients as well.

I'm extremely grateful to have John guide our cybersecurity efforts. His leadership and counsel have been invaluable and educational.

Chris Walker — Director of Operations — Praxent

He's making the whole organization look really, really good. Second, and more importantly, you should attach probes to John's brain as he works, study his behaviors, and seek to the greatest extent possible to reproduce those behaviors on all of your projects.

Kevin Hurwitz — Managing Partner — Praxent

Working with John, rather -- watching John do his work, continues to be a real joy. John is a self-starter, often managing up to a dozen simultaneous initiatives across multiple disciplines. John contributes at least to info-sec, application security, architecture, infrastructure, risk assessments, RFP's, compliance and IT.

You're probably one of if not THE most helpful people in the company. I feel like I work with you a lot on the various customer facing security items and trying to build up our program, etc. But it also seems like you work with EVERYONE a lot, so keep being helpful and a great partner all across the business.

David Pruitt — General Counsel — Screencastify

John's security capabilities across many different facets of our technology stack are amazing. His security understanding runs broad and deep. In trying to decide on our DNS infrastructure approach, John pointed out the security hole with our current [ ... ] Based on John's recommendation, we decided on a DNS approach that greatly improves our security posture and simplifies our infrastructure deployments.

Anson Kee — Senior DevOps Engineer — Screencastify

One thing that always stands out to me about John is how steady and consistent he is. I know that he is often being pulled in a hundred different directions but he is always prompt at answering my questions and supporting everyone else. I know that if I need something from him, it will always be done and done well.
