I’m a developer and systems builder focused on turning real-world complexity into structured, dependable technology.

I started building early. In 2012, I developed a community-based job discovery platform using Ruby on Rails that connected local homeowners with teenagers seeking short-term work—yard work, moving help, and odd jobs. It functioned as a digital job bulletin board before local marketplaces were common, designed to reduce friction in small communities where opportunity existed but coordination didn’t. That project shaped how I approach development: software should quietly solve problems, not perform for attention.

Over time, my work evolved toward infrastructure, data systems, and intelligent interfaces. I’m particularly interested in how AI can be used responsibly—not as a novelty, but as an invisible layer that improves clarity, confidence, and decision-making. My approach to AI emphasizes structure, verification, and explainability over hype.

One example of this mindset is a wildlife and animal-movement tracking system I built on my property. The project combined spatial mapping, observational data, and environmental context to model animal travel patterns across fields, woods, wetlands, and terrain features. It wasn’t about automation for its own sake—it was about understanding how systems behave over time when conditions change. That same thinking now informs how I design digital platforms.

I’m currently building ROLLIN, a platform focused on structuring and surfacing real-world accessibility data in a way that’s accurate, practical, and scalable. ROLLIN is being designed as both a user-facing product and a long-term data foundation, with careful consideration for search, mapping, and future machine-readable access—without overexposing complexity.

Alongside product development, I own Stackline Studio, an infrastructure, web development, and digital systems studio focused on helping small and mid-sized businesses strengthen how they communicate, operate, and present themselves online. Stackline works across web development, backend systems, networking considerations, and technical strategy bridging the gap between “a website” and a resilient digital presence that actually supports the business.

Outside of work, I spend a lot of time outdoors. I’m deeply interested in natural systems, movement patterns, and environments both physical and digital—and how thoughtful design can make them more navigable, honest, and humane.

I care about building things that last, treating data with respect, and using technology to reduce uncertainty instead of creating it.
