The Body is a System.
Engineer It.

1:1 health and performance consulting built on your blood work. I apply systems engineering to your biomarkers to find what's holding you back, then coach you through a prioritized plan to live longer, feel better, and perform at your peak.

SYSTEM STATUS

Optimized for Load

"Normal" is not Optimal.

Standard reference ranges are based on the population average. A population that is increasingly sick and metabolically dysfunctional. Being "in range" often just means you aren't dying yet.

As an engineer, I look for optimal operating parameters. We map your biomarkers against longevity and performance research targets, not the average of a sick population.

The same is true for athletes. "Normal" iron, hormone, and recovery markers can quietly cap your training, slow your recovery, and leave watts on the table. Whether your goal is a longer healthspan or a faster finish, the data tells you where the bottleneck is.

We don't just identify failure modes; we build a blueprint for your specific physiology. Based on your individual results, we stack-rank the most high-impact actions you can take—prioritizing the interventions that will yield the highest return on your health. This provides you with clear, key insights and a structured roadmap to improve your health in the most meaningful way possible.

Standard: "Your insulin is 18. You're fine."
Kestrel: "Your insulin is 18. This is early-stage failure."
Standard: "Your ferritin is 25. You're fine."
Kestrel: "Your ferritin is 25. That's limiting your endurance."

Built for Two Kinds of Goals

Most clients come to me for one of these. Many want both. Either way, we start with your data and build a plan around what will move the needle most for you.

Optimize Your Health

For people who want to feel their best for decades, not just avoid disease.

→Catch metabolic and cardiovascular risk early
→Dial in energy, sleep, and body composition
→Build a long-term longevity strategy
→Cut through supplement and biohacking noise

Optimize Your Performance

For endurance, mountain, and competitive athletes who want every edge.

→Find iron, hormone, and nutrient limiters
→Spot signs of overtraining and under-recovery
→Fuel and supplement for your training load
→Track progress across training blocks

What to Expect from Your Audit

Watch a walkthrough of my personal Kestrel Audit. I share my own biomarkers to show the results possible on this program—demonstrating that I practice what I preach while showing you exactly what your video analysis will look like.

You won't just get a report and be left on your own. I walk you through what your numbers mean, what to change first, and how to measure whether it's working.

What Clients Say

"This is precisely what I've been looking for for years. Incredibly useful—I'm planning to come back quarterly to track my progress."

— Tech Executive, Los Angeles

"I was worried about my cholesterol levels, but this report broke it all down and gave me a clear path forward. I finally feel like I understand what's actually going on."

— Endurance Athlete, Colorado

"The visualizations showing where I stand versus optimal ranges were a game-changer. It's not just numbers—it's a real action plan. Exactly the deep dive I was looking for."

— Biohacker, San Francisco

"Took my confusing lab results and made them actually make sense. Top 3 things to focus on, specific supplement doses, no guesswork. Started the plan the next day."

— Founder, Austin

Practicing What I Preach

Hi, I'm Jake.

Engineer // Ultra-Endurance Runner // Mountain Athlete

I'm an engineer by trade, and what I'm good at is optimizing complex systems: finding the constraint, fixing it, and measuring the result. Years ago I started applying that same approach to my own body, and I've been obsessed with health optimization ever since.

I'm also an ultra-endurance runner and mountain athlete. I put my own protocols to the test on long days in the mountains, so I know firsthand what it takes to stay healthy under real training load, and what it feels like when something in your blood work is holding you back.

Today I work with clients as a coach and consultant: reading your data, building a plan around your goals, and helping you follow through. Whether you're chasing longevity, a race PR, or both, my goal is to get you there with a clear, data-driven strategy.

Open Source Biology

I don't gatekeep my findings. I document my n=1 health experiments, blood work analysis, and performance protocols publicly.

Common Questions

Why not just use ChatGPT to analyze my labs?

You can — and you'll get a generic, hedged response that tells you to "consult your doctor." What you won't get is an analysis benchmarked against longevity-research targets (not standard lab ranges), a stack-ranked action plan built around your specific pattern of results, or a curated supplement protocol with actual doses. The Kestrel Audit applies a structured analytical framework built from hundreds of real audits — not a general-purpose language model prompted on the fly.

How is this different from what my doctor does?

Your doctor flags values outside standard lab reference ranges — ranges built from sick population averages. The Kestrel Audit benchmarks your results against optimal ranges from longevity and performance research, looks at biomarker patterns and interactions, and gives you a prioritized action plan focused on long-term performance. This is not a replacement for your doctor. It's the analysis your doctor doesn't have time to do.

Who actually analyzes my report?

Every audit is reviewed and written by me — a hardware engineer with 100+ audits completed and years of personal biohacking research. AI tools assist in processing and pattern matching, but the interpretation, recommendations, and final report are human-reviewed and validated before delivery.

What blood work do I need?

A comprehensive metabolic panel is the minimum — ideally including a full lipid panel, thyroid markers, fasting insulin, HbA1c, CBC, and inflammation markers (CRP, homocysteine). The easiest option is my annual panel on Good Labs, or Function Health for the most comprehensive membership. See the Get Blood Work guide for step-by-step instructions.

I'm an athlete. Is this for me?

Absolutely. As an ultra-endurance runner and mountain athlete myself, performance clients are some of my favorite to work with. We look at the markers that matter most under training load (iron and ferritin, hormones, inflammation, recovery, and nutrient status) and build a plan to support your training, not just your general health.

How long does it take to receive my report?

Base Reports are delivered within 48 hours of receiving your lab data. Deep Dive engagements include an intake questionnaire and a personalized video walkthrough, so timing depends on when your intake is complete. I'll keep you updated along the way. You'll receive your PDF report via email along with any supplementary materials included in your tier.

Is there a satisfaction guarantee?

Yes. If you're not satisfied with your audit, reach out and I'll make it right. This is a high-touch, personalized service and your results matter to me. Every report is a reflection of 100+ audits of refinement — I stand behind the quality.
