Summary
Jonas Bush is a Senior Software Engineer with over a decade of experience building high-performance desktop and web applications, currently developing enterprise solutions at FEI Systems from Peoria, Arizona. He has a strong track record in architecting scalable subsystems—most notably payment gateways, public APIs, and a purpose-built ORM—and consistently improves performance by refactoring SQL and redesigning data models to cut load times dramatically. Comfortable across C#, ASP.NET, JavaScript and SQL Server, Jonas has led teams, mentored developers, and owned end-to-end features for SaaS products in finance, membership management, and internal tooling. His background includes rapid problem-solving for large customer databases (reducing security table rows from millions to hundreds of thousands) and implementing PCI-compliant integrations, showing both attention to security and operational performance. Colleagues describe him as a pragmatic architect who blends hands-on coding with thoughtful system design to turn complex requirements into reliable, maintainable software.
