About

Solving complex problems.
Building reliable software.

I’m Jiman, a software engineer with 25+ years of experience turning complex challenges into practical solutions. I build clean, maintainable systems with a focus on performance, reliability, and thoughtful design.

I take a collaborative approach to technical leadership, from reviewing code to helping teams prioritize work. My background spans REST API design and integration, hardware-connected applications, and cloud platforms. I’m always learning and bringing that knowledge into the work I do.
