What Darren works on
Darren’s background is in platform engineering and software architecture, including event-driven exchange systems and secure payment technology. He leads CertLocker’s research into how changes to cryptography and certificate lifetimes affect certificate issuance, deployment and endpoint verification.
That research feeds into the platform so teams can prepare for changes in the infrastructure they already run.
