Justin Zagar South Florida available now full-time, remote or hybrid
Lead product designer and design engineer
I make the screens a business runs on, like the ones a warehouse uses to find a wheel or a family uses to share a list, and I build the software behind them.
I design the interface and build the system underneath it.
Thirty years of it, starting at fourteen on my home computer. The software I built for one wheel business has run it since 2012: 22,000+ orders, $3.5M+ in sales.
The listing tool I designed, feeding the store I built. One wheel: photographed on the rack, looked up by its Hollander number, priced, and on the storefront and eBay. 22,000+ orders through it since 2012.
Brainstorm, the brand engine I built. Move one colour and the whole identity follows.
Core, the shared desk my family runs on. Drop a file, leave a note, draw on it; the other person sees it land live.
2004. The Greeting Wizard I built for Payless Car Rental. Pick a card, write the note, and the card takes shape. The same round trip, twenty years earlier.
Imagine, the CMS I built, editing VAS, my own design language. Pick a theme and every control on the page follows the rule.
Pocket Juke, the music player I built for my own phone. Kotlin, Compose and Media3. Live tiles you hold to resize and rearrange, over a jukebox rainbow; a Now Playing screen that washes to each song's colour; search, a quick list and an equalizer.
The order ledger, 13,000+ orders through it. Every channel in one table: Sync pulls the new eBay sale in, a status change asks to be confirmed, and the row turns the color of where the wheel is.
2002. mySite, the self-publishing tool I built for the Muskego-Norway schools. A teacher filled in a form and their page changed, no webmaster in the way. The round trip, at the very beginning.
Punchlist, the Android task app I built for my family. Everything due on one rolling wheel: what is coming, what is due, what is done. A new task is a few taps, and it can wait to remind you until you reach the store.

Long way off
That count's a long way off. Count it once more?
20 A single-pole breaker
- What happened
- Your count is off from the system by more than 2 units and more than 10%.
- Why
- One miscount shouldn't change stock. You don't see the system's number, so it can't sway the recount.
- What to do
- Tap Recount and count it again from zero. The second count stands, and the office sees it flagged on review.

A concept, built in a week for one application. Scan the shelf, scan what's on it, and when a count is a long way off the app asks once more instead of letting one miscount change stock. Unsolicited, not a client, all data invented.
AllOEMRims.com Templatizer×
Templatizer classic, 2013 to 2019: the first generation of the listing tool. The same job as the 2026 one at the top of this cycle, built for a two-person shop.
The warehouse app, on the tablet by the packing bench. One order from the pack lane to a FedEx label in five taps: box, weight, cost, carrier, review. Designed for someone standing up with gloves on.

The long version
eight projects, start to finish
Each dot on this line is the same idea, rebuilt from scratch: a tool that takes the repeat work off somebody’s plate. Three of the stories below are on it. The rest are brand and product work from the same years, and the finished logos are under Brands.
2002
mySite
A district with eight schools and no way for any of them to change their own pages. I had started there at sixteen, still a student in the district. So I built a form: the school secretary filled in the principal's name, the phone number, the start and end times as radio buttons holding the three real answers, and it wrote the page back out. Two weeks start to finish. It cost nothing. Then I ran a session every month for any teacher who wanted to come, which is where the design actually got tested, because you find out very quickly which label is wrong when you are watching eight people fail at the same field.
Jump to the case study ↓2004
mySite Core 3
Rewritten in ASP.NET about three weeks after I came back to the district. It opened on a screen the first version never needed: Choose a site below to begin your editing session. One login across many sites, each showing when it was last updated, with a preview step before publishing. That is the version that outlived the school district. Through my freelance years the same bones got re-skinned client after client.
2004
ClientWire
Not a website. A reusable application shell (login, session security, a status and error library, roles, chrome) with per-client feature modules dropped into it. The proof it was a platform rather than a one-off is mechanical: across two unrelated deployments those shell files are byte-identical. The same shell ran a rental brand's customer complaint system and another client's back office.

2006
Imagine
The first one that shipped to somebody who was not a school. It went live on 22 December 2006, managing thirty pages of a national car rental company's public website. I know the exact date because the software recorded it itself, and those rows are still in the database twenty years later.
Read the case study →2008
air
The productized one. It had a name in the browser title bar, two logotypes I drew, a version number printed in the chrome, and five releases. Around twenty client sites over six years, white-labeled so the client's logo sat at the top and the firm's name went in the footer. The admin files are byte-identical across unrelated clients, which is what makes it a product with a deployment procedure rather than a folder I copied around.
2013
Templatizer
One wheel record becomes a finished eBay and WooCommerce listing in minutes instead of hours. It has run the business for fourteen years, and a second retailer licensed it and ran it as a paying customer, hosted and maintained on our own server. Same conviction as the school form in 2002, aimed at a harder problem.

AllOEMRims is winding down after fourteen years; the business is being sold. I am available now, full-time, remote or hybrid. The store is still online while it does. The conviction is not.
