Now I ship software.

A yeast scientist — seven years at New Belgium — who taught himself to build agentic AI, software, and websites. Same Six Sigma rigor — once aimed at living systems, now at the tools that run your operation.

This site, its code, and the live mycelium map below — I built all of it.

01 // who I am

The same hands that banked yeast now build agents.

For over a decade my job was making the invisible behave — yeast genetics, contamination forensics, fermentation curves. I spent seven years as Yeast Specialist at New Belgium Brewing, co-founded a craft distillery grain-to-glass, chaired the Microbiology subcommittee of the ASBC, and taught for White Labs' professional program.

Somewhere in there I bought a place and put it on Airbnb — the first one while I was still at the brewery. It worked, so I saved and bought a second, then a third: a three-property short-term-rental business in Asheville. Craft beer was the theme, which took no research on my part. For 10 years I was an Airbnb Superhost — a status Airbnb confers and re-checks against its own thresholds, not one you give yourself. I did the work I now automate: guest messaging, chasing reviews, taking bookings, coordinating turnovers, keeping listings straight across every channel they were on. The rentals out-earned my salary as a scientist, so I ran the 80/20 and left New Belgium for hospitality. I don't run the rentals anymore. The ten years of running them is why I know which guest messages an agent can answer and which ones still need you.

Then I pointed the same discipline at code. The microbes never cared about my résumé; neither did the compiler. Both reward the person who measures, iterates, and ships. Today I design and build agentic AI tools, software, and websites with the Six Sigma rigor I used to stabilize fermentations.

The result is rare: one operator who can walk a production floor, debug a contamination, and then hand you the dashboard that tracks it — or the agent that answers your guests at 2am. I work with Asheville breweries, makers, restaurants, farms and nonprofits — and with clients nationally who need science-grade thinking and modern tooling in one place. I'm now pointing the same tooling at short-term-rental operators.

// the through-line

Mycelium is a network that ships nutrients. AI is a network that ships decisions.

Problems are hard to see — but let's find and solve them together.

02 // what I do

Four disciplines that used to be four careers.

Most clients hire one and find the next one solved by the same person — which is exactly where the value compounds.

Agentic AI & Automation

Practical AI that removes busywork and pays for itself in saved hours — built by someone who actually ships agents. The panel on this page runs on the same skills, not a mockup.

  • AI agents: phone, chat, guest messaging, email triage, booking
  • RAG knowledge bases & internal copilots
  • Document pipelines & reporting automation
  • Forecasting & compliance assistants
Proof: the live agent panel, generative map, and this entire site were built by me. The front-desk load they take over, I carried by hand across three rentals.

Fermentation & Microbiology

Lab-grade science for anyone who makes things with microbes — or worries about them.

  • Yeast banking, strain selection & propagation
  • Contamination forensics & QC program design
  • Sensory panels, shelf-life & scale-up
  • In-house micro lab buildouts
Proof: 7 years owning yeast at New Belgium; ASBC method-setting.

Web & Software

Fast, modern sites and custom tools — built and maintained, not handed off and abandoned.

  • Websites, e-commerce & booking systems
  • Custom dashboards & internal apps
  • POS / inventory / API integrations
  • Batch-tracking & data-viz tools
Proof: you're looking at it — hand-coded, no template.

Process & Strategy

Six Sigma discipline applied to operations, quality, and product launches — the connective tissue that makes the other three pay off.

  • DMAIC process-improvement projects
  • SOPs, HACCP & regulatory readiness
  • Product launch & scale-up playbooks
  • Fractional quality / ops leadership
Proof: the same DMAIC that cut batch variability at New Belgium — now applied to operations and launches.

03 // track record

Built in the lab, proven on the floor.

Before the catalog of what I can build, here's what I've already done.

2020 — 2022
Microbiology Subcommittee Chair · Featured Speaker
ASBC & White Labs Accelerated Brewing Program
Led the ASBC Microbiology subcommittee developing methods and standards adopted across the U.S. brewing industry. Served as a featured speaker across multiple White Labs professional sessions on applied yeast science and QC technique.
2015 — 2022
Yeast Specialist
New Belgium Brewing Company · Fort Collins, CO
Owned yeast health, propagation, and strain performance across large-scale lager and ale fermentation at a nationally distributed brewery. Drove consistency with viability/vitality monitoring and pitch-rate optimization, supported novel-flavor R&D, and applied Six Sigma to cut batch-to-batch variability.
2012 — 2015
Head Distiller & Co-Founder
Old Town Distilling Co. · Fort Collins, CO
Co-founded a craft distillery and built grain-to-glass operations from the ground up — mash, fermentation, distillation, barrel aging, blending, and QC for whiskey, vodka, and gin. Designed sustainable sourcing including a spent-mash-to-farms program, and built and trained the production team.
2012 — 2014
iGEM Team Lead & Research Assistant
Colorado State University, Dept. of Microbiology
Founded and led CSU's iGEM team through recruitment, sponsorship, and international competition. Directed yeast-based synthetic biology — genetic construct design, bioinformatics, codon optimization — and led a gluten-free beer yeast strain development project.

// the fermentation ops diagnostic

Find what's quietly costing you batches.

One week, $1,500 flat. I go through your process and the batch data you already keep, find what's costing you product, and hand you a fix list ranked by payoff. You decide whether the findings were worth the fee — if they weren't, you don't pay.

// questions

Questions, answered straight.

The things people ask before they book. If yours isn't here, just send it.

What happens on the free scoping call?

Thirty minutes, Google Meet or phone. You describe what's bleeding time or money; I tell you how I'd approach it and the likely path. No pitch — if I'm not the right fit, I'll tell you who is.

What does it cost?

The scoping call is free. A focused 60-minute paid consult is a $150 deposit, credited toward your project. Full builds are scoped and quoted in writing — at a fixed price — before any work begins, and starting ranges are shared on the call.

Do you work remotely, or only in Asheville?

Both. Fermentation and lab work that needs hands on equipment is on-site around Asheville and Western NC. AI, web, dashboards, and strategy I deliver remotely for clients nationwide.

Do you actually build it yourself?

Yes. One operator scopes it, builds it, and stands behind it — the agent panel, the live mycelium map, and this entire site are my own work, not a template or a subcontract.

How long do projects take?

Most packaged engagements run about two to eight weeks depending on scope. You get a timeline alongside the written quote, plus 30-day support after launch.

What if I don't know which discipline I need?

That's what the scoping call is for. Pick “Not sure yet — help me scope it” on the form, or just describe the problem and I'll map it to the right work.

// Book a time

Book a call — or start a paid engagement.

Two ways in. Grab a free 30-minute scoping call to talk it through, or lock in a paid 60-minute working session with a deposit. Either way you pick a real slot on my calendar and get instant confirmation.
