For twenty-three years I built instruments to see things people couldn't — hyperspectral and multispectral cameras that measure light far past what the eye catches, and the software that turns that raw signal into something true. Lately I've been pointing the same instinct inward: instead of mapping the physical world, mapping myself.
A habit of seeing it early
At Surface Optics I started as a part-time lab tech taking reflectance measurements and worked my way to senior software engineer. Somewhere in the middle I got the company's hyperspectral processing running in real time on a PlayStation 3's Cell processor — about a hundred times faster than the best PCs of the day, and far cheaper than the $25,000 FPGA boards we were building. We never shipped it, but it told me where things were headed: I was porting our pipelines to CUDA in early 2008, before most people had a reason to care, and ended up running a 16-band camera's deconvolution at full video rate on a laptop GPU while the old code crawled at seconds per frame.
I mention this not to brag about GPUs but because it's a pattern. When the generative models arrived, plenty of smart people around me said “I tried it, it wasn't very good.” I felt the same thing I'd felt about the Cell and CUDA — this is the frontier — and I left to follow it.
Why I started mapping myself
The turn was personal, too. Around the time I turned forty, my father died, a long relationship ended, and I'd started questioning the direction my career was pointing. I took a year to build a cabin in the woods, moved to Portland, and started using language models for everything — work, and the slower work of understanding myself.
At some point the obvious idea landed: model me. It's not as strange as it sounds — it's what we already do when we get to know someone. We build a model of a person, mapping what goes in to what comes out. I wanted to do that deliberately, from my own words: years of journals, notes, messages, reflections — enough text to approximate how I actually think, so I could ask it why I feel and do what I do.
I'm not trying to replace myself, and it can't be perfect — we surprise ourselves; there's always noise. But once, after fine-tuning a small model on my writing, I asked it whether it wanted to talk about a painful moment. It just said: “No.” Not a chatbot's apology, not a wall of hedging — an honest no, the kind I'd give. The kind an ex once told me I was famous for. One data point, not science. It still felt like something.
I use it to check myself now — my patterns, what I keep circling, where I spiral. It doesn't get hungry or tired or defensive, and it remembers far more of me than I can hold at once.
The bigger question
What pulls at me is whether richer models of people could improve the things that actually matter — collaboration, hiring, learning, connection. A résumé or a profile captures a sliver of who someone is; I think there's room for something better, where people are matched in a far richer space than keyword search. Some of it is speculative, some of it already works, and all of it is testable. That's the work I want to do, with people who see it too.
You can meet a version of the idea now: Inscape, a privacy-gated mirror you can ask questions — the access I give you decides how much of me you see — and Throughline, the open-source piece you can run on your own writing, locally.
What I'm actually looking for
Day to day I build AI systems — retrieval, evaluation harnesses, agent workflows, and privacy-aware applications of language models: the unglamorous engineering that makes this stuff hold up in the real world. I'm looking for work — a role or a collaboration — where strong engineering and honest product thinking matter more than hype.
Off the clock
Yoga (practicing, and hoping to teach). Cooking — lately 100% fresh-milled whole-wheat sourdough. Self-reflection, recovery, and the practice of paying attention.
If this resonates
I'm looking for people like me — builders and researchers a little out in the wilderness, drawn to where AI, memory, identity, and human connection meet, and wanting to build something real there with someone. Whether that's a role, a collaboration, or just a conversation: I'd like to hear from you, and you'll be heard.
