JoshHenderson-Jardim

I’m based in Brooklyn, where I build software for clients and develop my own projects. I’ve built tools for a coaching business, a reader for Mac and iPhone, and an app for watching movies with friends, along with a ginormous graveyard of other projects and many more under development.

Client work

  • Post Grad Project

    I built tools for David’s coaching business to organize client information, process coaching calls, and help him prepare follow-ups.

  • Futrsport

    A custom Shopify storefront for goalkeeper training equipment, live at futrsport.com.

  • King MLS

    I built a system that applies Mike’s property-ranking formula to his saved MLS searches and brings the results together for him and his clients.

  • Franki Wellness

    A live coaching website bringing Franki’s offer, story and resources together, with clear ways to learn more or get in touch.

  • Jonathan Orenstein Photographic

    A portfolio website for Jonathan Orenstein’s photography, with eight collections and a full-screen viewer, live at jophotographic.com.

Things I’m building

Overlap

My app for finding people who are curious about the same things. It turns the posts you save on X into a map of themes you choose, so you can compare it with a friend’s. It’s an early beta.

Overlap’s example comparison, with made-up people.

Founder Portal

My substitute for social media as a place to learn: a private website that brings together sources I choose, what I’m studying and ideas I want to return to. It’s also where I practice for interviews.

My library filtered to Articles and posts, with posts saved from X, each with an Open button.
Posts I saved from X on my phone in October, kept in my own library.

Watch Party

A private movie night app for friends. Native Mac playback, shared controls, and conversations that continue between watch sessions, served from a Raspberry Pi.

A Watch Party session: over a video of a listening room, the player shows “Guest (Sam) seeked to 0:00:09”, and beside it Sam’s message “Hold on, are those tube amps?” is tagged 0:00:09.
Sam jumps back to 0:00:09, the other player follows, and Sam’s question is tied to that moment. Recorded with two test guests on one Mac.

Read Along

My Mac generates a reading, and the iPhone and iPad companion keeps it ready to take with me. Listen, follow the highlighted words, and tap a passage to jump there. The browser reader also narrates this site’s project stories.

Read Along in Listen mode, highlighting the word being read in a short sample reading.
The Mac app highlights each word as it’s read, and the iPhone companion plays the same readings away from the computer. Neither is publicly released yet.

Clubbr

A web app for Brooklyn club nights. The crowd pieces together each DJ set’s tracklist, and if you opt in, you can meet people who were at the same nights.

Clubbr’s example tracklist: a made-up track marked Community supported after three of four reviewers chose Matches.
Clubbr’s example tracklist, with a made-up set and reviewers. Three “matches” make a track community supported; votes only decide which unknowns get researched first.

Eyedentity

My project for finding people to build and learn with. I’m starting with a Brooklyn guide to places, events and communities.

A little more about me

I like making things, from the go-kart I built as a kid to the software I work on now. I’m interested in DIY speakers, electronics and robotics, and I spend a lot of time thinking about how we understand the world and live together. Soccer and movement are a big part of my life too.

More about what I’m exploring

Working together

If you have a project in mind, we can talk through what it needs. You can send me a message, ask for free help with AI, or book a twenty-minute call, arranged by email.

I’m also open to full-time or part-time roles on interesting projects.
