As co-founder of Sonant Consulting Group, I bring ~15 years of technical expertise and business acumen to the development of customized telecommunications solutions. Our team specializes in:* Providing expert guidance on VoIP infrastructure and application development* Designing bespoke telecommunications systems for small ISPs, VoIP companies, and businesses seeking tailored solutions.* Offering support and maintenance services for legacy systems.Throughout my career, I've developed a passion for finding creative solutions to complex telecom challenges using best of breed open source technologies.

As a consultant, I work with companies of all shapes and sizes in a lot of different capacities. The majority of the projects I end up working either fall into the category of Systems Engineering (linux/devops/integration), or Telecom/Network Engineering.A lot of my business comes from the relationships I maintain with ITSPs and enterprises on the telecom side. I act as their point of contact for any new client setups or maintenance they might need; my systems work usually tends to be more short term, consisting of building a deliverable and then handing it off to an ops team to maintain.

I'm a member of a small development team, my focus is usually more in the systems area -- dealing with systems architecture, automation, scaling, stability, etc.
