Hi, I'm Jace Kim.

I sell things, build things, and occasionally break things.

I build the software small businesses run on, for a defense-parts company, a medical practice and a manufacturer's rep agency.

Pulse

Client | Senmark Industries

Running a defense-parts company on one system

Product design and engineering

Senmark sells parts to the US government. Pulse reads every morning's government bids, scores them against supplier stock and margin, and carries each deal from the first quote to the paid invoice.

Billing ledger

Client | Medical practice

Payment reports that read themselves

Design, engineering and data migration

Weekly payment reports used to be retyped into one workbook on one computer. Now each report is read in, matched against about 79,000 visits, and approved by a person before it counts.

Shown here with made-up patients.

The billing dashboard with made-up data: payments by year for four doctors, this year's totals, and the weekly payment reports.
One week's payment report being read: each scanned name, date and amount beside what was read, matched to a visit, with one line unmatched and one name spelled differently.
Chart pulls

Client | Medical practice

One photo of the day sheet, every chart printed

Design and engineering

Every week, staff spent hours pulling 50 to 200 patient charts by hand and copying codes onto index cards. Now they photograph the day sheet, check the names, and print one file with every chart in order, plus what goes on each card.

Patient data stays inside a HIPAA-covered account. Shown here with made-up patients.

The chart pulls screen after a run: all 11 patients on the day sheet pulled, ready to print.
A yellow card filled in for one made-up patient: procedure codes 99214 and 90833, and four diagnosis codes.
Commission hub

Client | Manufacturer's rep agency

Every statement in one ledger

Design and engineering

Each manufacturer sends commission statements in its own format. The hub ties them into one ledger, and every number links back to the line it came from.

Shown here with made-up companies.

The commission hub's sales sheet with made-up companies: each customer account, its owner, the manufacturers it buys from, sales this year and the change from last year.
One account opened: a donut of this year's sales split across five manufacturers, with amounts and shares.
tly

Passion project | Game and app

A cozy town where my to-do lists live

Design, engineering and game design

Neighbors keep daily routes, houses wear down if I ignore them, and a voice assistant takes my notes. Whitley lives there too. He's the one following you around.

Making a career out of figuring things out.

I build the systems small businesses run on.

For Senmark Industries, a defense-parts company, I built Pulse to run their bids, sourcing and purchasing. For a medical practice I built a billing ledger and an app that pulls patient charts from a day-sheet photo. For a manufacturer's rep agency I built a commission hub.

Off the clock I'm building tly, a cozy town for my lists, and walking Whitley, who has never once read a spreadsheet.
