Now building — QuarterSection · Oklahoma mineral rights intelligence

I turn messy domains into working systems.

I'm Tyler Milligan — co-founder, engineer, and writer. I spent years at Microsoft and Google explaining complex systems. Now I build them: a statewide data platform, AI-era products, and modern software for real businesses — every layer, end to end.

Who I am

A builder with a writer's mind.

I started in science at CU Boulder — a neuroscience lab, then Arctic atmospheric research with a co-authored paper in Biogeosciences. From there I spent years as the person who makes complex systems make sense: technical writer at Google, digital product manager, then technical writer at Microsoft on HoloLens, Mixed Reality, and Mesh.

In late 2024 I stopped documenting other people's systems and joined QuarterSection as its fourth partner — the one who builds. My three co-founders bring the vision, the industry depth, and the connections; I turn it all into a working product. Every layer is mine — nightly ETL pipelines, the SQL estate, the APIs, the React frontend, the cloud infrastructure, the docs — plus a portfolio of my own products and client work.

I think in systems, I document like it's a love language, and I'd rather build the thing than buy it.

QuarterSection

Oklahoma mineral rights intelligence — deep data, made human.

Visit site

Hundreds of thousands of people own the oil and gas underneath Oklahoma — and most of them can't see what's happening down there. The data exists, but it's scattered across slow government databases and written in century-old legal jargon.

QuarterSection pulls it into one place: your wells on a map, your production history, your paperwork — clean, fast, and priced for a person instead of a corporation. It competes on depth with platforms built by entire engineering departments, at a fraction of their price.

Three co-founders, one builder. My partners steer what mineral owners and operators need, carry the legal side, and open doors. I make it real — data engineering, backend, frontend, DevOps, security, product, design — every line of code and every daily decision.

  • A fleet of nightly scrapers and ETL pipelines that crawl state and county records with zero human in the loop
  • Entity resolution reconnecting financial records to physical wells the government never gave a shared ID
  • An AI document pipeline that reads scanned legal PDFs and extracts the facts
  • A ~100-table Azure SQL estate that rebuilds itself nightly with zero downtime
  • Data-quality systems that auto-flag impossible values before users ever see them
  • An interactive well map that draws each well's real drilled path — bottom-hole trajectories reconstructed from OCR'd survey documents, not just surface dots
  • A grounded, cited AI assistant (the Learn Assistant) that answers mineral-rights questions from a vetted corpus with sources — and declines rather than guess
  • One-click portfolio exports to multi-tab Excel workbooks, generated in the background

Products and client work shipped alongside the flagship — same playbook, different domains.

Product · grounded agents

Grounded Agents

Retrieval-grounded chat, five domains. A gallery of AI agents that answer only from real sourced material — U.S. immigration & border law, fitness, health, oil & gas, and injury rehab — citing every claim and declining when the sources don't cover the question. One Cloudflare Worker over 60,000+ sourced passages, with password- and quiz-based access control and per-user rate limits.

Product · thestackmap.com

The Stack Map

The AI tools landscape, mapped. An interactive library of 156+ tools and 31 real workflows — not just what each tool does, but how they connect in practice. Includes a stack-builder quiz that recommends tools for how you actually work.

Product · outdoor hub

Outdoor Hub

Every condition, one dashboard. Real-time weather, snow, trail, water, and road data unified from NOAA, USGS, state DOTs, and avalanche centers — 11+ activity dashboards across the American West, so you check one site instead of six agencies.

Real-time data Multi-source APIs

Product · AI training coach

Workout Coach

A coach that reads my Strava, computes real training load, and rewrites my week every morning — evidence-graded rules make every decision; the AI only writes the words. Push + email check-ins, a live calendar feed, adaptive plans, and a chat coach with code-enforced safety rails.

Product · recipe matrix

Recipe Matrix

Turn any recipe into a cooking matrix — ingredients down the side, technique across the top — so you see what gets combined and when instead of scanning a wall of prose. Paste it, drop a link, or photograph a cookbook page; you get the matrix, a shopping list grouped by aisle, and a shareable link.

dügood

Main-street AI modernization. Ongoing consulting for a Seattle junk removal & donation pickup company — including a real-time Google Reviews engine I built for their Squarespace site, streaming a live 5.0★ rating across 150+ reviews straight onto the page.

04 — Work with me

I do this for other businesses too.

QuarterSection taught me how to be a company's entire product and engineering org in one person. dügood proved the same playbook works for main-street businesses: a modern web presence, automated workflows, and AI where it actually earns its keep. If your business runs on software from 2012, I can fix that.

Shipping log

Nearly everything I build lives in private repos, so my public GitHub looks quiet. This is the real cadence: every commit, pull request and review across all of them, refreshed from GitHub every night.

4,398

contributions in the last 12 months, 99% of them in private repos. 4,308 so far in 2026, against 1,017 in all of 2025.

That's more than every one of 2,248 randomly sampled GitHub accounts (how I checked, Nov 2026).

Off the clock

The work is only half the story. I'm happiest in motion — splitboarding into untracked snow, standing on summits I had to earn, wandering cities I can't pronounce. I cook constantly and too much, mostly for the people I love. Family and friends aren't what's left over after the work — they're the reason for it.
