I help founders and growing businesses make better technology decisions before expensive mistakes slow growth.
Most software projects do not fail because of bad code. They fail because goals were unclear, ownership was fuzzy, scope expanded without discipline, or early architecture decisions could not support real-world operations. My role is to reduce those risks early and help companies build systems that actually ship — and continue to perform as the business grows.
I work with clients to clarify:
• What they are truly trying to achieve
• Where workflows, handoffs, or systems are breaking down
• What should be built now vs. later
• How to move forward within real budget, timeline, and operational constraints
That starts with understanding the current business, processes, and data flows — then designing practical systems that are scalable, maintainable, and aligned to outcomes. Where it adds real leverage, that may include automation, integrations, or AI.
⸻
Experience & Approach
I bring 30+ years of hands-on experience across healthcare, finance, legal, nonprofit, SaaS, and data-intensive environments.
My background includes:
• Software architecture
• SaaS platform strategy
• Backend systems and APIs
• Systems integration
• Workflow automation
• AI-enabled business systems
• Product and technical leadership
I operate in a hands-on senior advisor model:
• I personally lead architecture, technical assessments, planning, and key decisions
• When execution support is needed, I can coordinate trusted developers under clear direction
• You maintain one accountable senior point of contact throughout the engagement
Clients get executive-level judgment where it matters most — without wasting senior budget on every implementation task.
⸻
How I Typically Work
Successful projects usually follow a disciplined sequence:
1. Alignment – Clarify goals, risks, constraints, and success metrics
2. Solution Definition – Turn business needs into practical technical decisions
3. Architecture Review – Validate the direction before heavy investment
4. Phased Roadmap – Define milestones, sequencing, and priorities
5. Execution Support – Guide delivery, decisions, and course correction as needed
This approach creates momentum, reduces rework, and leads to systems that last.
⸻
Clients Hire Me To
• Serve as a Fractional CTO or senior technical advisor
• Build MVPs and new SaaS platforms the right way
• Rescue stalled or fragile software projects
• Modernize legacy systems
• Design automation and AI-assisted workflows
• Integrate disconnected tools and data sources
• Improve scalability, maintainability, and reliability
• Get an unbiased view of build vs. refactor vs. replace
⸻
If you need someone to simply complete tickets, I may not be the best fit.
If you want an experienced partner who thinks strategically, challenges assumptions, and helps you make sound technical decisions, we will likely work well together.
I’d be glad to learn more about your project and discuss whether there’s a strong fit.
