Fractional CTO | Enterprise Data Architect

Get the Senior Technical Leadership You Need, Without the Full-Time Cost

As your Fractional CTO, I join your leadership team to provide the technical vision, team mentorship, and architectural oversight you need to scale with confidence.

Do you have a clear product vision but an uncertain technical path?

You’ve found your market and your customers are asking for more. But your engineering team is stretched thin, critical architectural decisions are being delayed, and you lack the senior technical leader to guide your company through its next phase of growth. This is a common challenge, and it’s where I can help.

How Can I Help?

I provide technical leadership in two primary ways, providing the right level of support to match your needs.

I Need a Technical Leader

Service: Fractional CTO

For companies needing ongoing strategic guidance, team leadership, and architectural oversight. I join your leadership team, providing the expertise of a seasoned CTO for a fraction of the cost of a full-time hire.

I Need A Project Solved

Service: Data & Search Solutions

For companies with a specific, complex challenge that requires deep, hands-on expertise. I lead the design and implementation of enterprise search, data harmonization, and multi-model data architecture projects.

Meet David Cassel

I’m a pragmatic technical leader with over 30 years of experience helping companies get more value out of their technology by improving efficiency, supporting growth, and making day-to-day operations run more smoothly. I founded 4V Services and grew it to an 18-person team, delivering over $11 million in value to clients ranging from startups to Fortune 500 companies. I focus on building teams and systems that work in the real world. That means creating an environment where people communicate openly, collaborate effectively, and contribute their best ideas. I also help non-technical executives understand what their technology is really doing for the business so they can make informed, confident decisions about where to invest and how to move forward.

My Approach

Pragmatic AI Adoption

AI is a powerful tool, but it’s not a magic wand. Poor software development practices with AI just produces poor results faster. My approach is to use AI to augment the expertise of your team, implementing it responsibly to boost productivity while keeping the human developer accountable for quality.

Collaborative Team Building

I believe that high-performing teams are built on a foundation of trust and buy-in. I work with your engineers to establish shared standards and effective processes, creating a collaborative environment where every team member is empowered to do their best work.

Focused Architecture

I specialize in designing and building robust, scalable data architectures. Whether it’s selecting the right database, a real-time data pipeline, or an enterprise search solution, my focus is always on delivering a practical, results-driven solution that meets your business needs today and scales for tomorrow.
