Get in TouchAbout
Five by Five Consulting is a solo software consultancy founded by Dave Hanson, a senior IT professional with over 30 years of experience building, shipping, and maintaining software systems across a wide range of industries.
From enterprise platforms to greenfield startups, I've worn every hat — developer, architect, team lead, and technical advisor. I work directly with business owners and technical teams to design and deliver software that solves real problems, on time and on budget.
As a solo consultant, you get my full attention. No handoffs, no junior stand-ins. Just decades of experience applied directly to your project, augmented by modern AI tools that amplify what one experienced engineer can deliver.

AI-Augmented Approach
AI doesn't replace experience — it multiplies it. I use modern AI tools throughout my development workflow to deliver more, faster, without cutting corners.
Faster Delivery
AI-assisted code generation, testing, and documentation means projects move from concept to production in less time, without sacrificing quality.
Higher Quality
Automated code review, comprehensive test generation, and intelligent refactoring catch issues early and keep codebases clean.
Solo, Not Small
AI tools let a single experienced engineer operate at the capacity of a small team. You get enterprise-grade results with the efficiency and accountability of a solo consultant.
