About

Who I am

I'm a U.S. Army Warrant Officer specializing in joint and strategic targeting. My professional background sits at the intersection of complex decision-making, systems thinking, and operational execution in high-consequence environments. Across joint and multinational contexts, I've spent my career translating ambiguous problem sets into structured plans, measurable outcomes, and executable workflows.

In parallel, I work with early-stage founders and high-performing professionals as a coach and advisor — helping them navigate uncertainty, build resilient personal and professional systems, and make better decisions as their organizations scale.

My personal interests focus on the practical application of software, data, and AI to improve human performance, operational visibility, and decision quality. I'm currently in graduate study with an emphasis on systems engineering and human–AI integration, building tools and frameworks that operate well in fast-moving environments.

Beyond Destruction: Bridging the Gap in Artillery Effects Expertise

★ CW5 John A. Robinson Eagle Writing Award

In Large-Scale Combat Operations, the U.S. Army faces a persistent tactical gap in artillery employment driven not by a lack of systems, but by an insufficient understanding of surface-to-surface munitions effects among practitioners. Although doctrine such as FM 3-60 emphasizes effects-based targeting, and tools like Joint Weaponeering Software and the Advanced Field Artillery Tactical Data System provide statistically rigorous solutions, their effectiveness at the tactical level is constrained by operator understanding, data quality, and time. Reliance on simplified adjudication tables and reductive destroy–neutralize–suppress frameworks distorts expectations and erodes confidence in fires, despite modern artillery demonstrating unprecedented precision and effectiveness in contemporary conflicts. To close this gap, the paper proposes an advanced munitions effects course developed beyond software operation — building deep, technical expertise in blast, fragmentation, fuzing, aimpoint manipulation, and nonlethal effects, modeled on established joint and sister-service programs. Centered on 131A Field Artillery Targeting Technicians as the Army's effects subject-matter experts, this course would enable more accurate, flexible, and scientifically grounded targeting decisions, ensuring artillery can fully realize its potential in LSCO under both permissive and constrained conditions.

Witan

Private · in active development

A personal life-organization harness built from many small local AI models working together — not one big model doing everything.

Most AI assistants are one large model trying to do a hundred jobs. Witan bets the opposite: a swarm of small, specialized models running locally, each doing one narrow job reliably and handing work to the next — like regions of a brain. I capture a thought by voice; the swarm turns it into the right thing — a calendar event, a personal to-do, or a task for an AI agent — and I watch the whole operation from a single dashboard. The wager is that accuracy and trust beat raw speed, and that small models you can actually verify beat one big black box.

The Witan dashboard — in daily use.
Witan architecture, at a glance A voice capture feeds a swarm of small local models, which route each thought into a calendar event, a to-do, or an agent task — all overseen from a single dashboard and running locally on a private network.
How it works, at a glance — captured by voice, routed by a swarm of small local models, overseen from one dashboard.

Built so far

  • Voice-first capture that turns a spoken thought into a calendar event, a to-do, or an agent task
  • A dashboard in daily use — information bots, a calendar with two-way sync, and personal to-dos
  • A small fleet of local machines running open-weight models over a private network
  • An analog morning brief — a printed daily paper that starts the day present and off the phone

What's next

  • A task board and live telemetry for every model and agent in the swarm
  • A long-term memory the swarm can be asked about
  • An approvals inbox for the decisions only I should make
  • Pushing the probabilistic models toward deterministic, repeatable behavior

The code lives in a private repository — not public yet, but I'm genuinely excited about building it. Happy to talk through the architecture and the ideas.

Soldiers don't wait for AI. They build it.

Featured for my team's second-place finish at the U.S. Army's Vantage Edge 2 AI competition — a five-day sprint where 300+ participants across 42 teams shipped production-ready AI solutions to real operational problems. Out of Joint Base Lewis-McChord, we built an AI workflow that consolidated land, ammunition, training, and readiness systems into a single forecasting and planning dashboard, addressing a challenge shared across Army divisions.

Coaching

Founders, executives, and high-performers

I coach and advise founders and operators across early-stage startups — most often around decision quality, leadership under uncertainty, and translating strategy into operating systems.
