Full-Stack GTM Engineer / Growth Architect

A GTM Engineer & Growth Architect portfolio. Systems in production.

A curated selection of systems I've designed and built. Each deep dive walks through the thinking, the strategy, the technical execution, the trade-offs I chose, what broke, and what the numbers say.

the thesis

In marketing and GTM, we trade in insights — how to do it, how to frame it, how to offer it. But what looks like insight is, most of the time, intuitive assumption. A guess.

What I came to realize is that the best motions I've designed — in my own business or someone else's — came from systems thinking, and from knowing the buyer as intimately as you'd know a partner, not a persona. That's the real leverage. I've spent most of my career solo or fractional, and the only reason I could outcompete bigger companies was that one detail.

A business, the way I see it, is a living system, not a fixed machine. It grows, adapts, and responds to its environment — that's how it survives and evolves. The customer isn't outside that system; they're an integrated part of its ecosystem.

It may sound silly, but GTM is too often a rigid blueprint, when the optimal thing to be is the organism's nervous system — its behavioral response, the way the business feels out the market. Its job is to find the business's ecological niche: the one space where it can thrive without being rejected by the environment.

In a world where AI has collapsed the cost and time of building software, the market is overflowing — and everyone is fed up with outreach and ads that sound like everyone else's. My move is the opposite of more volume: learn the exact way the ICP talks — the words, the mannerisms, the pain and the outcome they name themselves — and feed it through inbound, outbound, and content alike, all stitched together. That's what I call customer-driven systems: data and neuropersuasion woven into one, so you're not competing in a market — because you're not offering what you think they need. The lead feels understood, not sold to, and the guard never goes up. You can get a sneak peek in the deep dives below.

Final round · CEO

A YC startup's SDR lead flow, rebuilt as a take-home — capacity math over effort.

A take-home strategy for ReSquared (YC W21). It reached the final round with the CEO, and the Head of RevOps said they'd implement it. The core move: capacity math over effort — ~60 leads/day in, real throughput 20–25, half the inflow. More SDRs wouldn't fix it.

about

By the time I'm writing this, I've tinkered with ~30 LLM models, a few harnesses, and a dozen custom solutions I built myself. I still think AI is an amazing thinking and building partner — extremely useful for someone who knows what they're doing and the output they want, and awful at doing anything on its own.

I'm a multi-hyphenate — the Virgil Abloh route, if I'm honest about the lineage: a civil engineer who ended up in taste and persuasion instead of structures. The engineering is where the systems thinking comes from — you don't get to improvise a structure — even though I never practiced it. I ran my own mid-luxury resale store, where storytelling, taste, scarcity, and positioning beat follower count every time. Then I consulted and co-produced product launches — offers and direct-response marketing at scale. Apex is where all of it converged: my operating lab, solo, end to end, selling to the most skeptical ICP there is, where fine-tuning isn't polish — it's survival. Now I want to bring that mix somewhere it compounds — a team, real resources, harder problems.

The BDR is almost a state-of-the-art of who I am — an intersection of a dozen disciplines.
