About the Founder

Patrick Badley — Founder & Principal Architect, Purple Cardinal Technology

Patrick Badley

Founder & Principal Architect · Minneapolis

Architecture rigor with founder velocity.

I am a software architect and principal full-stack engineer with over a decade of experience designing, scaling, and operating high-throughput distributed systems, consumer fintech platforms, and enterprise identity infrastructure.

During my tenure leading platform identity and authentication at Upstart, I led architectural migrations to Keycloak, reduced account creation latency from 2 seconds to sub-750ms, and spearheaded passwordless mobile authentication across millions of users.

I founded Purple Cardinal Technology to partner directly with engineering leaders, venture studios, and ambitious founders. I bring senior technical judgment, hands-on architectural execution, and clear tradeoff analysis to every engagement without agency overhead.

“We relied on Patrick to guide important authentication and platform architecture decisions. He had a remarkable ability to break down complex problems, explain the tradeoffs, and help the team move forward with confidence. His contributions across passwordless authentication, Keycloak modernization, API performance, and developer tooling made a lasting impact. Patrick combined a long-term architectural perspective with the practical judgment needed to deliver.”

Yamini Maddirala

Senior Software Engineer · Upstart Identity & Platform

“When we had to make architecture calls, I trusted his judgment, and he was usually right. He thinks things through, and he's good at explaining why one approach makes more sense than another without making anyone feel dumb for asking. He's also really dependable. If he said he'd get something done, it got done, and I never had to chase him on it.”

He's one of those people you can trust with any challenge, whether it's a really complex software design, or a difficult people situation. He has a great deal of skill, good instincts, and a learning mindset that serves him well in every situation.”
