About Me

Experienced methodical and practical architect, specialising in cloud services and technology, with a strong security background.

Designing a global compliance and payment processing service, Nick has leveraged AWS Cloud Services to deliver the next generation of Cloud Telephony services for compliance and PCI DSS Payment services. Delivering the first QSA-Validated Global PCI-DSS Level 1 telephony and payment service platform.

Utilising best of breed tools from vendors such as EMC, AWS, and Splunk, the platform is self healing, auto scaling, and highly elastic in its response to customer demands, and the needs of businesses operating in different territories, in different timezones.

A strong understanding of Splunk, and a global deployment of the tool in all the regions where the platform operates, makes me an experienced Splunk architect, and user.

I have presented for Amazon Web Services and Splunk on best practices and sharing my experiences for both on several occasions.

Client Testimonials

  • Nick is a phenominal colleague and has transformed the systems archiecture and evolved the Cognia platform into an award winning, world class SaaS platform scaled around the world (on AWS [US, EU, APAC]) all the while achieving some of the hardest externally assessed certifications like PCI-DSS etc. Nick is the core part of my dev/ops team, reliable, intelligent, inventive and collaborative with a great work ethic and awesome sense of humor. I look forward to any opportunity to work alongside Nick, a great guy to have in the trenches.

    Andrew Dunn - CTO, Cognia
  • Nick is *the* best systems guy I have come across and is now permanently in my black book for future engagements. Nothing phases him, and he is equally at home configuring a Cisco router from the serial interface as he is Cloud Forming secure and scalable AWS infrastructure. Very developer centric, highly skilled and GSOH. And he's not just a back room guy - in front of customers he is convincing and thorough. An ace player
