About Redfield Diagnostics
We’re not here to reinvent the wheel; We’re here to make it turn better. Redfield Diagnostics specialises in the overlooked, the under-documented, and the absolutely mission-critical.
Modern businesses still rely on software written decades ago; Systems no one wants to touch but everyone depends on. That’s where we come in. With deep experience in legacy code, low-level diagnostics, and high-stakes modernisation, we cut through bloat, avoid hype, and help organisations regain control of their infrastructure.
Redfield Diagnostics was founded by Dan Redfield, a former senior engineer with a background in reverse engineering, diagnostics, and critical system recovery. With experience ranging from high-traffic corporate intranets to hardware-level game porting, Dan built this consultancy around the principle that competent legacy support shouldn’t be an afterthought; It should be a core service.
We don’t offer one-size-fits-all answers. Our approach is diagnostic first: we assess the system you’ve got, identify the risks and bottlenecks, and give you options, not ultimatums. Whether you're dealing with an undocumented .NET tangle, a business-critical Access database, or a brittle VB6 app holding your operation together, we can help you chart a realistic path forward.
We also know that the biggest challenges aren’t always technical. Sometimes the real problems are political, procedural, or cultural; A fear of change, a history of failed upgrades, or a lack of trust in vendors. That’s why we work directly with decision-makers, devs, and stakeholders alike, translating between business needs and technical realities.
Redfield Diagnostics is deliberately small, ruthlessly focused, and transparent by design. We don’t outsource, upsell, or disappear behind jargon. We tell you what we’d do, and then we help you do it.
