Kai Cao

I am a software developer with over 19 years of experience building engineering, scientific, and business software systems across energy, utilities, benefits administration, and insurance. My background combines software engineering with domain-focused problem solving. I have worked on fluid-property calculation tools, PVT and dew point applications, engineering data workflows, cloud-based services, and enterprise web systems. Over the years, I have developed applications using .NET, C#, SQL Server, Entity Framework, Azure, Angular, React, WPF, WinForms, VBA, and related technologies. I enjoy building practical, maintainable tools that make complex workflows easier to understand, validate, and use — whether that means wrapping a trusted calculation engine behind a clear interface, turning messy data exports into clean engineering data, or helping teams make better decisions from their existing systems. I also maintain a small collection of technical notes and engineering-software demos around fluid-property calculation, GC/PVT data workflows, and cloud-based visualization. My professional focus is on software that fits how people actually work: reliable, understandable, and useful in real operational or business environments.
