Summary
David Carle is a seasoned software leader and founder with over 12 years of focused experience delivering bespoke systems for small and medium businesses as Director and Senior Software Developer at D20 Software Ltd. He blends hands-on development in C#, Delphi and ASP.NET with deep database expertise across Oracle, SQL Server, MySQL and FileMaker to turn messy off‑the‑shelf workflows into tightly integrated, productivity-boosting solutions. His background includes senior development roles supporting government and energy-sector systems at Lockheed Martin and Walker Martyn, where he provided 3rd-line support and architecture for robust, mission-critical applications. David’s skill set spans business analysis, requirements capture, CRM implementation, data migrations and integrations with tools like Outlook, Excel and Sage—areas where many developers struggle to bridge technology and operations. Based in Motherwell, Scotland, he brings a pragmatic, longevity-focused approach to software design, favouring maintainable systems that “stand the test of time.” Beyond coding, his long career reflects an uncommon combination of engineering discipline and client-facing consultancy that helps organisations realise measurable ROI from bespoke software.
