Client Reviews
What Clients Say
HIRE WITH CONFIDENCE! And then thank me later!! This was my first opportunity to work with Darrell, and things could not have gone any better. Not only is he incredibly thorough and meticulous in the quality of his work, but he is equally accommodating in the consultative nature of his approach and in the documentation and materials that he provided as a supplement. Darrell saw opportunities to make improvements that we had not considered and was proactive in providing options and recommendations.
I couldn't be happier with the work. As a hiring expert that previously scaled/hired for Amazon, Facebook, and Wish, I can say that Darrell is a star.
Another job done amazingly well. Darrell did things I didn't know were even possible.

SRE and DevOps consultant focused on SaaS infrastructure. Previously at Paramount+ and LexisNexis, where I led zero-downtime migrations and managed production Kubernetes clusters at scale. Now I help SaaS companies build the same caliber of infrastructure without the enterprise price tag.
