Building with AI

AI products I designed and built.

HelloAlfie never create a calendar event again

Say who and when: a teammate, your whole team, or anyone with an email. Alfie checks everyone's calendars and sends the invite.

Solo build, with one engineer on scheduling2025–26helloalfie.ai Available in Claude
HelloAlfie homepage: 'Never create a calendar event again', Connect to Claude and Get Started in the nav, and a Try Alfie Free button
The problem

Booking one meeting still takes a chain of back-and-forth messages, and booking links just hand the work to the other person.

Result

In early release, with people booking real meetings. Next: finding what else Alfie can do beyond a confirmation.

HelloAlfie on the web: a request for coffee with Maya on Thursday, a glowing Booked card, and an arrow to the new event on the week's calendar. Names are changed.
On the web: say who and when. Alfie checks both calendars, books it and sends the invite.
An iMessage thread with Alfie: Lunch with Jackie this week, a proposed time at the Ferry Building, Yes, and a Booked card
Or in iMessage: one text, reply YES, booked.

Hayes see what your site could be

Design feedback on any screen, or three new working homepages built from your own site.

Solo: product, design, code2026hellohayes.ai Available in Claude
Hayes homepage: 'Design and product feedback, without hiring a team', a box to paste a link or screenshot, and a live review showing a problem, the fix, and before and after screens
The problem

Most AI answers read like a machine wrote them: long lists, hedges, no priorities. Product teams need to know what to fix first.

Result

Live with a free first review and plans from $5, and available in Claude as a connector. I use it every day on real product work.

Redesign my site
A sailing charter's original homepage on a phone, then three fully working redesigns Hayes built from it: Golden Hour, Dusk and Harbor Chart
Paste one link. Hayes builds three new homepages, fully working, from the business's own site.
Review a screen
A real Hayes review of the Mailchimp homepage: a faint free-trial bar, a personalization form that blocks the page, and a cookie banner competing with it
Send any screen. Hayes marks the three problems that matter most and says what to fix.

Expa

Companies from Expa, Garrett Camp's startup studio.

Aero private flights by the seat

The website and iOS app for semi-private jet travel, from search to the day of travel.

Senior Product Manager, team of 82022–24aero.com iOS app
Aero website, 2024: a booking bar with origin, destination, guests and a Round trip / One way toggle over an aerial photo of an Aero jet; 'The Perks of Flying Private. Book by the seat.'
The problem

Flying private was expensive, opaque and slow to book. Aero sold it by the seat, so booking had to feel as easy as an airline.

Result

Add-ons in the booking flow automated 20% of manual work, 30% of existing users moved to the app, and Q4 revenue rose 18%.

Aero iOS app, Trips: 'Hi, Aaron. 1 week until your trip to Los Cabos', with the upcoming flight card
Aero iOS app, Day of travel: 'Your trip to Los Cabos starts in 5 days', with terminal, car service, baggage and check-in
Aero iOS app, Inflight Experience: the ERJ 135 aircraft and onboard experience
Aero iOS app, Concierge: a chat with the Aero concierge about arrival time and a car to the hotel

Spatial meetings in AR and VR

A shared 3D space for teams to meet. Early access research led us from AR headsets to VR on Oculus Quest.

Product Manager2019–21Quoted in AR Insider VentureBeat
Spatial's public launch website, November 2020: 'Spatial. How Work Should Be.' with 'Try for free in VR/AR' over a shared VR workspace

The public launch site I shipped, November 2020

The problem

Spatial started as AR for HoloLens, an expensive headset few teams owned. Adoption was capped by hardware.

Result

The pivot to Quest and the new onboarding drove adoption: about 1 million users.

Spatial website in March 2020: 'Collaborate from anywhere in AR', with HoloLens 2 event links
Before · March 2020: AR-first, on HoloLens
Avatars gathered around a table in a Spatial VR space, with one person joining by webcam
After · VR on Quest, open to anyone

An all-in-one financial service for people who work for themselves.

Product Manager, Marketing, Ops2018–19collective.com
Collective homepage: 'The all-in-one financial solution for self-employed entrepreneurs' beside an accounting dashboard

The problem

Solo business owners juggle taxes, bookkeeping and payroll across too many tools.

Result
