What I’m building

Two products, both in development. I build things I want to use myself.

In development

Seller OS

Profit and analytics for marketplace sellers.

See what each order really earns once marketplace fees and costs come out, and how your shop is doing over time.

Example order

Sale priceRp150.000
Marketplace fee−Rp15.000
Shipping−Rp9.000
Packaging−Rp4.000
You keepRp122.000

In development

Quest Board

A shared board for plans and memories.

I’m building it for my girlfriend and me, to keep track of places to visit and things to do together.

Try a quest

Save an idea
Plan the visit
Keep the memory
