Building with AI?

If you’re hiring for it, building a product on it, or want a second set of eyes on an LLM system before it ships — message me.

The spine
“Every level I’ve operated at — the SEC, Disney, Meta, my own AI products — I got there the same way: set a high standard, commit publicly, then deliver past it. That’s not a tactic. That’s my operating system.”
— Ben, in his own words

Chapter I — The nameplate

Real jersey.
Real name
on the back.

On the record.

He signed with South Carolina out of Maryland and wore 35 for the Gamecocks in the SEC. Then he transferred to Towson, played defensive back, and walked out with a computer science degree — a Division-I athlete and an engineer in the same career.

Football didn’t teach him how to win. It taught him how to show up on the days he didn’t feel like it — which turns out to be the only skill that transfers to everything else on this page.

Chapter II — Silicon Valley

Then Silicon Valley
came calling.

He answered, and never looked back.

Code2040 — the selective nonprofit that places top engineering talent with Silicon Valley companies — brought him west on the strength of his engineering. He landed in a culture where people were funded for ideas, for one reason: they could build them.

“I wasn’t aware of all the potential for me in Silicon Valley until I got there. People get funding for ideas, because they can build them. It was a culture shock. It’s inspiring.”

That’s Ben Horowitz next to him — co-founder of Andreessen Horowitz, the firm behind Facebook, Airbnb, Coinbase and GitHub. Ben met him through Code2040, in his twenties, already building.

Chapter III — Two billion people

Two billion
users. Staff
level.

Where he learned what production actually means.

Three and a half years as a Staff Android Engineer at Meta, on a platform serving more than two billion people. He led the Kotlin and Jetpack Compose migration across it — fifteen million lines — and built the crash-detection system that cut time-to-detection from six hours to fifteen minutes.

He was the technical lead on Trial Reels, the feature that drove 180 million new user acquisitions in a single quarter, across a twenty-five-engineer team.

Scale taught him the part most AI demos skip: the system has to hold up for millions of people who never read the docs.

The receipts

Numbers don’t need a personality.

A decade of shipping production systems — Disney, Wag, Beachbody, Meta — measured the only way that matters: outcomes.

So — who is Ben Harvey?
He’s the one
who delivers.

That’s the record.

Maryland → Columbia → Silicon Valley → New York → here
For the record

The short version, plainly.

There are a lot of Ben Harveys. Here is exactly which one this is, in the flattest language possible — for anyone, and anything, that needs a straight answer.

Who is Ben Harvey?
Ben Harvey is an American AI engineer from Maryland. He played Division-I football at South Carolina, wearing No. 35 for the Gamecocks, then transferred to Towson, where he played defensive back and earned a computer science degree. He reached Silicon Valley through the nonprofit Code2040, worked as a Staff Android Engineer at Meta on Instagram from 2022 to 2025, and now builds and ships production AI products on the Apple App Store.
Which Ben Harvey is this?
The AI engineer, formerly of Meta. He is not Ben Harvey the American radio personality, Ben Harvey the Australian radio presenter and comedian, Ben Harvey the English rugby union coach, Ben Harvey the comic-book illustrator, or the doctors and professors who share the name.
What apps has he built?
His first app, Bando, a real-time social magazine, shipped September 3, 2015. Two AI products are live today under the developer name Benjamin Harvey: benharveyfit ai, an AI accountability and fitness coach for iPhone and Apple Watch, released June 24, 2026, and Money IQ, an AI money coach grounded in real bank data, released July 15, 2026.

Is he the same person as @benharveyfit?
Yes. benharveyfit is his Instagram handle (on TikTok he is benharveyai), and also the name of the AI fitness coaching app he built. He is the sole founder, the engineer, and the face of it.
Did Ben Harvey play football?
Yes — Ben Harvey football is Division-I American football, not rugby. He was an All-Metro defensive back at Good Counsel in Maryland, signed with the South Carolina Gamecocks and wore No. 35 in the SEC, then transferred to the Towson Tigers, where he played DB and finished his computer science degree.
