Creative Developer

Building beautiful,
thoughtful interfaces.

About

I turn ambiguity
into polished interfaces.

I'm Karl—a developer at the intersection of design sensibility and engineering rigor. Over 5+ years, I've built products across fintech, AI, employee experience platforms, and client-facing web applications, always with obsessive focus on the craft of the interface.

I have a background in graphic design (AA from Clark College) and earned a Best Interface Design award at Epicodus' coding bootcamp. That combination—visual instinct plus engineering discipline—is what I bring to every project.

When I'm not building, I'm climbing rock walls, making music, or shooting photos. These aren't hobbies—they're how I keep the creative pipeline flowing.

What I Do

01

Interface Design

Schema-driven, reusable component systems in React and TypeScript. Strong eye for hierarchy, rhythm, and responsive craft.

02

Full-Stack Reach

Frontend architecture through backend APIs, WebSockets, and cloud services. End-to-end ownership of the systems I build.

03

AI-Powered Products

Building AI workflows with structured orchestration, session management, and user-facing controls—not just prompt wrappers.

04

Performance & Systems

Architecturally-minded approach to speed. Caching, streaming, efficient update patterns where responsiveness matters.
