Hi, I’m David Klee, Founder and Chief Architect of Heraflux Technologies®, a leading provider of SQL Server consulting and performance tuning services.

In a world that grows more unpredictable by the day, your business needs more than uptime. You need SQL Server performance that holds up under pressure, infrastructure that adapts to change, and systems that support the staff you already trust.

That’s where I come in.

With over two decades of hands-on experience, I help organizations transform Microsoft SQL Server environments—from legacy on-premises systems to complex cloud and hybrid infrastructures—into high-performance, resilient platforms that align with business goals.

But my work doesn't stop at the database.

I specialize in tuning the entire SQL Server stack, including hardware, virtualization, storage, networking, and Windows Server performance. Because database performance issues rarely exist in isolation—and the cost of guessing wrong is simply too high.

• Faster SQL Server environments without replatforming
• Reduced infrastructure & licensing spend through precision tuning
• Increased uptime and high availability without unnecessary complexity
• Actionable insights - no vague recommendations or guesswork

This is real-world, system-level SQL Server engineering—applied with speed and focus to get your team measurable results without disruption.

I work alongside your existing staff—not over them. From DBAs to CIOs, I bring clarity and confidence to every layer of the SQL Server environment.

My goal?

To make your SQL Server platform a strategic advantage—not a performance bottleneck, hidden cost center, or operational risk.
