I find the structure underneath a thing and rebuild it so it holds — as software, automation and workflows.

Systems design and automation for founders and teams, through Spirit River Inc. Proof below: two production platforms I architected and shipped solo, and twenty years of studio work.

Open Ephemeris — an interactive chart rendered inside Claude
Open Ephemeris
Open Ephemeris A precision calculation engine, exposed to both apps and AI agents.

The calculation layer underneath anything that touches the sky — birth chart apps, AI agents, compatibility engines, research tools, astrocartography. One core serves a REST API and an MCP server, so the same answers reach a developer's app and an agent's tool call. Covers Western astrology, Human Design, Bazi, Vedic and more.

ELA Map
ELA Map Place is personal.

A personalized geographic intelligence workspace. Astrocartography and Human Design cartography share one model of place, rendered on an interactive globe and built on Open Ephemeris underneath.

Recording, mixing, mastering and production for audio and picture. Twenty years of the original systems work: signal chains, sessions and deadlines that have to hold under pressure.

Time, made visible

The structure of time and space in nature, in long exposures of my own.

Night long exposure: clouds smeared into rippled streaks with faint star trails above a forested valley and a rocky creek.
A small waterfall over dark rock into a river, the water blurred silky by a long exposure. Black-and-white photograph of clouds streaked by a long exposure above a rugged mountain range and valley.
Star trails wheeling in concentric circles around the pole above a mountain ridge, under a deep blue sky. Black-and-white star trails in concentric circles over a snow-patched alpine lake and peaks.
Working together

Systems design and automation

Most broken processes aren't missing a tool — they're missing a model. I work out what is actually happening underneath your operation, design the system it should be, and build it: software, automation and AI agents that hold up after I leave.

I run three businesses on my own on the strength of the systems behind them. Engagements run through Spirit River Inc., from a short architecture review to a full build. If something here resonates, start a conversation.

How I help Systems design — mapping how work, data and decisions actually flow, and where they break. Automation — workflows, integrations and AI agents that take the repetitive load off people. Product builds — strategy through shipped, full-stack software. Agent tooling — MCP server design, and vetting which tools are safe for agents to use.

"Learn a structure well enough to feel what's out of alignment before you can name it."

I'm a systems architect based in Santa Fe. On paper my path looks scattered — sound, the body, the image, software. From the inside it has always been one practice: learn a structure deeply enough to feel where it's out of alignment, then design what lets it move freely.

Sound

Twenty years at Spirit River Sound. Bringing a record into the world is a systems problem wearing an art form: signal flow, sessions, people, deadlines and release, all designed so the creative moment has room to happen and the finished work lands.

The body

Over a decade teaching anatomy and kinesiology and practicing craniosacral therapy and structural integration. The body is the most elegant system I know — tension, support and flow, where a change in one place reorganizes the whole. I developed classes, programs and training frameworks, and organized teachers into a cooperative.

The image

Real estate photography as a working business, and a long personal practice in long-exposure and time-lapse photography: images that make the structure of time and space in nature visible. Star trails, moving water and turning light are systems too; the camera just slows them down enough to see. The night sky and time-lapse behind this page are mine.

Software

I taught myself to code and architected two production platforms solo, Open Ephemeris and ELA Map — from data model and infrastructure to product and the business end. Today I design and build systems, automation and agent tooling through Spirit River Inc.

Each of these became a business I started and ran myself: the clients, the operations, the money, the marketing. That is where the architecture proves itself. Today I run Open Ephemeris, ELA Map and Spirit River Sound on my own, because I built the systems and structures that let one person carry all three.

What ties it together is care for the people inside a system. A good structure isn't imposed; it's found, then given a clear form so it can be used. Turning something subtle and hard to see into something precise and useful is the work I love most.
