Professional Values & Approach

Quality First

I believe that sustainable software development requires a foundation of quality code, comprehensive testing, and thoughtful architecture. My approach emphasizes building systems that are not only functional but maintainable and scalable over time. The most important attribute of code is readability. (And working correctly. Tied.)

Business-Focused Solutions

Technology should serve business objectives, not the other way around. I work closely with stakeholders to understand business requirements and translate them into technical solutions that deliver measurable value. Technical designs must change as requirements evolve; ideally, the architecture is flexible enough to accommodate new requirements, but sometimes that must change too (a decision not made lightly).

Continuous Learning

The technology landscape evolves rapidly, and I maintain cutting-edge expertise through continuous learning and hands-on experimentation with emerging tools and methodologies, including AI-assisted development platforms. Claude Code in particular has been a great boon to my velocity, and exercises my code review skills thoroughly.

Collaborative Leadership

Great technology solutions are built by great teams. I focus on mentoring developers, establishing best practices, and creating collaborative environments where teams can deliver their best work.

Industry Experience

My diverse industry background provides me with unique insights into different business models, regulatory requirements, and technical challenges:

• E-commerce: Order management systems, payment processing, inventory automation
• Automotive: Auction platforms, inventory management, high-volume transaction processing
• Healthcare: HIPAA-compliant systems, patient data processing, claims management
• Science: Large-scale data analysis, GIS, environmental monitoring systems
• Government: Secure data processing, compliance frameworks, system integration

Location & Availability

Based in Petaluma, California, I serve clients throughout the North Bay Area and work with remote teams worldwide. I offer flexible engagement models including project-based consulting, ongoing technical advisory services, and interim technical leadership roles.

Whether you need assistance with a specific technical challenge, strategic technology planning, or comprehensive system modernization, I'm committed to delivering solutions that drive business success.
