Welcome

Here’s What To Expect

Receive insights on how to continue performing at an elite level when faced with uncertainty — timeless principles I used to reach Head of Engineering at two F500s after breaking into tech from a non-traditional background.

Playbooks and lessons learned are taken from how I’m operating my business ventures and the 10 years spent in corporate.

Goal: improve the signal to noise ratio on the Internet one article at a time.

Everything originates back to positioning yourself to gain a competitive edge in spite of changes to your industry — Permanent building blocks in your skillset so that you’re excited for what comes next.


I believe in taking a multi-disciplinary approach to develop an arsenal of skills and a collection of mental models will keep you competitive in the long term. Expect the topics covered to follow suit.

Unfortunately, the majority of modern-day knowledge work still operates like we’re still in the industrial era. You can see us being forced down a path to become a cog in the machine starting from K-12 education and well into our professional lives — so let’s change that.

This quote sums it up nicely.

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

-Robert A. Heinlein

This approach is heavily inspired by some of the greatest polymaths of all time such as Aristotle, Leonardo Da Vinci, and Richard Feynman.

Live like a modern-day version of my role models and keep a well-documented trail of what’s share-worthy — that’s how we landed on the name “Casey’s Codex”.

P.S. - Paying tribute to Charlie Munger, the absolute GOAT of mental models and finding the signal in a sea of noise.

About The Author

Hi there, I’m Casey the guy behind this publication.

Click here for a recap of what I’m up to after quitting corporate.

Over the past decade, I’ve taken an unconventional approach to career growth.

I entered the tech industry from a non-traditional background and became the Head of Engineering in two F500 companies. Here are the highlights and major inflection points.

  • Finance at P&G: worked on a 9-figure product portfolio straight out of undergrad. Learning to navigate a large global org early on proved to be critical later on.

  • Engagement Manager at Accenture: joined Canada's Data Science and AI practice right when the AI market caught fire during the mid-2010s.

  • Data & ML Instructor at Brainstation: reinvoked an old passion and an itch to teach and play in the Education space again. Selling tutoring services has been my side hustle since I was in middle school.

  • Head of Engineering in F500s: quickly grew to be responsible for everything within the function while scaling teams and helping many others grow their careers in parallel.

Behind the scenes, I navigated several critical transitions and reinvented myself several times in order to solve new problems and access new opportunities.

Not to mention, I’ve had a rollercoaster of ups and downs with no signs of slowing down anytime soon.

Who Is It For?

Hyper-generalists who strive to be polymaths — a person able to conquer multiple disciplines at will.

Read on — in the next 30 seconds, you’ll know with conviction whether it’s for you or not.

Those who are intellectually curious, analytically driven and intrinsically motivated to get to the bottom of complex ideas. Ideal for those who operate in volatile industries who want to thrive under chaos and future-proof their skills to remain competitive in the long run (without burning out).

Naturally, you’ll stay up late at night digging into topics such as:

  • How to beat the odds and thrive in high-stakes, competitive environments (e.g. crypto, AI, investing, poker)

  • Frameworks to get to the bottom of things such as systems thinking and reasoning from first principles

  • Have a strong bias towards timeless principles to guide how you operate on a daily basis

If you read up to this point, I’d bet good money that you already:

  • Follow thought leaders such as Naval Ravikant and probably already re-read The Almanack on a regular basis.

  • Binge content from podcasts like the Tim Ferriss show. I’ve easily consumed 500+ hours of his podcast over the years.

  • Read publications such as Farnam Street on evenings and weekends.

  • Spent way too many hours in the productivity and self-help sections — deep down you know you’ll throw 100s of more hours at it.
