Product lead · Founder, Carmate Cambodia · Phnom Penh, UTC+7

I build products for markets where the playbook doesn't apply.

For six years I've designed, built and run Carmate, Cambodia's one-stop marketplace for new and used cars, from zero: four products, a two-sided business, and the entire codebase. Before that: architecture at the Bartlett and Grimshaw in London, and a vanilla import business I built from scratch.

02 / Field notes

Small problems, fixed properly

Short ones. Each started with something a user did that I didn't expect.

Maps · Validation

The showroom in the river

A dealership pinned its showroom in the middle of the river. The location picker now rejects a pin on water, off a road, or outside Cambodia.

Forms · Friction

The telecom dropdown

Every phone form asked people to pick their network. I mapped each telecom's number prefixes, and the product now works it out from the number.

Seller Central · Control

Control over automation

When a model goes on promotion, cars already in stock don't change on their own. Staff choose which ones join, so brands aren't afraid to run offers.

03 / The products

Four products, one system

Designed and built end to end, for a market where most users are new to buying online.

04 / Other work

Built for others, and built before

A bank platform, an operation run for the same bank, and the first business I took from zero.

PropertyMap

KB Daehan Specialized Bank

The internal platform bank staff used to record loan collateral: map integration, valuation reports, and area prices with their history. I designed the UI/UX, built the React frontend, and trained the staff.

Repossessed-car store

KB Daehan Specialized Bank

The bank appointed Carmate as its partner to run its repossessed-car store: marketing, a buyer base of dealers and individuals, stock, sales and repairs.

Vanilla import

Park & Company, Korea

Suppliers in Madagascar, then the harder part: finding who in Korea buys vanilla and how much, pricing from landed cost, and building the B2B customer base, brand, packaging and ordering website.

05 / About
Portrait of David Park

From architecture to product.

I trained in architecture at the Bartlett (UCL) and worked at Grimshaw on the London Bridge Station redevelopment, coordinating large systems between many parties. Since then I've built things from nothing three times: a vanilla import business, a collateral platform for a bank, and Carmate.

At Carmate I've owned everything a product lead touches: research with dealers and brands, the business model, UX and the design system, frontend and backend code, deployment and growth, as a team of two. Today I ship the codebase myself with AI-assisted development.

Next: a remote product lead role where product and growth pull in the same direction, in marketplaces, fintech or consumer platforms. I work from Phnom Penh, UTC+7.
