Act I · What I'm best at

Pick a skill. Watch it work.

Skill 1 of 4

Product & UX

Several dozen features and dozens of UX improvements shipped at Hello Haven. My rules: fewest clicks to the aha moment, sign-up right on the landing page, and depth and motion that show people where to go next. This site runs on the same rules.

Act II · Try it

Don't take my word for it. Run the numbers.

Three small, live models of how I think about growth. Change the inputs and watch what moves.

The usual sign-up
Built my way
Usual sign-up: of 1,000 visitors, reach aha
Built my way: of 1,000 visitors

Click through both phones. The drop-off rate is an illustration, not a benchmark: I measure the real one before I start cutting.

Act III · My story

Competitor. Operator. Founder. Builder.

  1. Roots

    Raised to own the outcome

    I grew up in a family of blue-collar business owners where the standard was simple: figure it out, or let me do it. It made me resourceful early, and it's still how I work. I take the problem, not just the task, and when something is beyond me, I learn it fast or call someone in my network who has already solved it.

  2. Competitor

    Division I track

    Division I track is a sport where every rep is timed and every result is public. It taught me to train for the metric that matters and to stay accountable to it. If it's not hard, it's not worth doing.

  3. 2021 to 2023

    Operator

    I came into technology through operations. At Word On The Block I went from Head of Operations to COO in nine months, then ran operations as fractional COO of Salesa AI, an AI outbound sales product.

  4. 2022 to now

    Founder

    I founded Martech Studios and acquired a micro SaaS. I've closed $750K+ in sales personally and built the technology and marketing systems for companies that have raised $25M+ combined, across 50+ projects.

  5. 2026 to now

    Building personal AI

    As Director of Growth Engineering at Hello Haven, a personal AI company valued at over $50 million, I own both sides of the business: real-time vision and calling in the product, and the growth engine that acquired 30,000+ users at under $30 each.

  6. Next

    The interface that acts for you

    Software is shifting from tools people operate to agents that act on their behalf. The companies that win will make that shift feel simple and trustworthy. That's the product problem I want to spend the next decade on.

The proof.

Seen enough? Send me the problem you're stuck on. I'll reply with how I'd attack it.

Act V · How I work

How I work

  • Fewest clicks to aha

    Every click is a chance to lose someone. Sign-up lives on the landing page and works for everyone. Getting there takes hard cuts.

  • Motion is a map

    Depth and motion show people where to look and what to do next. Looking good is a side effect.

  • Less is more

    Charles Perrow showed that complex, tightly coupled systems fail in ways nobody predicts. So I cut parts, steps, screens and data until nothing is left to confuse anyone.

  • Listen, then cut

    Listen hard enough and customers tell you exactly what to remove. Fewer clicks, happier people.

Act VI · What you get

What your team gets.

  • Websites, apps and tools

    Web, mobile and internal tools. Give me an afternoon and you'll have a working app.

  • Real-time AI features

    Voice, vision, video calls and agent memory. Shipped end to end.

  • Product updates on autopilot

    Release notes and update posts that publish themselves the moment you ship.

  • Analytics people trust

    First ad click to daily use, simple enough to act on.

Quick learner. Faster decision maker.

Finale · Let's talk

Got something hard? Let's build it.

I want a long run on a product that's hard and matters, with people who've stayed up until 2 a.m. on something because they couldn't put it down.
