Philosophy & Approach

Core principles that guide every project and client engagement.

Data Sovereignty First

Your data should remain under your complete control. Every solution prioritizes self-hosted, vendor-neutral technologies that eliminate external dependencies and maintain privacy by design.

Client-First Approach

No vendor lock-in, ever. Solutions use open-source, industry-standard technologies that ensure portability, reduce costs, and provide long-term sustainability regardless of vendor changes.

Security by Design

Security isn't an afterthought—it's built into every layer. From network architecture to application design, security controls are integrated throughout the infrastructure stack.

Knowledge Transfer

Your team learns to maintain and extend solutions independently. Comprehensive documentation, training, and ongoing support ensure long-term success without dependency.

Why Harvest Technology Systems?

After 25+ years in technology infrastructure, I founded Harvest Technology Systems to help organizations reclaim control of their data and technology stack. The name "Harvest" reflects the culmination of decades of experience, bringing together proven methodologies with modern innovations.

Too many organizations have become dependent on cloud services that create vendor lock-in, escalating costs, and data sovereignty concerns. My approach emphasizes self-hosted solutions that give you complete control while maintaining enterprise-grade security and performance.

Every engagement is about more than just technology—it's about empowering your team with the knowledge and tools to maintain and evolve your infrastructure independently. This ensures sustainable success long after the project is complete.
