About Selbytech
Experienced technology leadership for growing businesses
David Selby – Fractional CTO & Technology Leader
I am an accomplished technology leader with over 15 years of experience delivering scalable cloud platforms, enterprise SaaS solutions, and AI-driven systems. My career spans director and vice president–level roles across global enterprises like Honeywell, high-growth startups, and SaaS companies. I specialize in translating business strategy into secure, resilient technical architectures that improve efficiency, enable automation, and support growth.
I hold a Bachelor of Applied Science in Chemical Engineering from the University of Waterloo, am a licensed Professional Engineer (P.Eng.) through Professional Engineers Ontario, a Certified SAFe Agilist, and earned an MBA from CTO Academy’s Digital MBA for Technology Leaders program in London, UK.
I help technology-driven organizations bridge the gap between vision and execution by bringing seasoned technology leadership, strategic clarity, and operational discipline — without the cost of a full-time executive. Whether a company is transitioning from early product–market fit, preparing for fundraising, or overcoming scaling challenges, I work as a trusted leader who gets things done.
Professional Background
My career has been defined by building and leading technology teams through complex transformations in regulated, high-availability environments. Here are some of the highlights:
Honeywell — Director of Information Technology (2021–2023)
At Honeywell Corporate, I directed a geographically dispersed team of 26 members across the U.S., Mexico, India, Belgium, France, and the Netherlands. I drove a company-wide migration to ServiceNow that transformed customer service delivery and designed a comprehensive IT service catalog that produced an 80% SaaS margin increase. By optimizing resource sharing through vCenter APIs, I achieved $2M in direct cost savings. I also architected Remote Migration Services infrastructure that positioned the business to access a $700M annual market opportunity.
Honeywell — IT Management Principal (2018–2021)
Leading security for Honeywell’s SaaS energy management operations, I delivered flawless outcomes in four consecutive ISO 27001 audits. I grew adoption of the Virtual Engineering Platform (VEP) to over 40,000 virtual machines, enabling a net annual benefit of $300 million for the business. I directed a major data center migration to Equinix, transitioning from NSX-V to NSX-T, and developed an innovative cost redistribution system using Python and VMware vROps for on-demand SaaS billing.
Honeywell — IT Program Manager (2015–2018)
I secured a $5M SaaS contract with a major European utility through a micro-segmented deployment strategy for smart-meter portfolio optimization. I built a disaster recovery framework achieving a 2-hour RTO and 10-minute RPO for critical utility meter reading systems. I also championed the deployment of Honeywell’s public cloud Distributed Control System (DCS) — enabling digital twin technology — and pioneered one of the first five global VMware vSAN implementations.
DynamixE Inc. — VP Digital Solutions (2023–2025)
At DynamixE, I engineered Kubernetes-based architecture for web-deployed Ignition SCADA on Civo and GCP. I managed a $1.5M project deploying critical infrastructure for a cancer immunotherapy company and led a pilot with Pieces.app that increased development team efficiency by 30% through AI-Copilot adoption. I secured a strategic partnership with Civo for scalable SaaS infrastructure and architected a VMware alternative using Verge.io.
