Remote product studio · USA & UK
Launch the product your customers actually use
We design and build customer apps, Shopify storefronts, and marketplaces — then publish them on Google Play, the App Store, and your domain. English-first, on a schedule that overlaps US business hours.
Apps, Shopify, and marketplaces — designed, built, and published for US & UK founders.
- Written scope before we build
- 9 apps live on Google Play
- Storefronts you can open today
TikAccs marketplace
TikTok accounts, listed with the live catalog
Browse USA, UK and other audience listings on KDF Tech. Counts, prices and verification come from TikAccs. Nothing here is a TikTok endorsement.
What US teams hire us for
One studio. The whole launch.
Founders come to us when the product has to look custom, go live, and keep running — not when they want another template demo.

10Featured reviews
USA · UKRemote delivery focus
★★★★★
Play Store launch without the chaos
“We needed a Flutter customer app and clean store listing. KDF Tech handled UI, builds, and Play Store publishing. Communication was clear across time zones — felt like a US product team.”
★★★★★
Shopify redesign that actually converts
“Our old theme looked generic. They rebuilt the storefront with stronger merchandising and mobile checkout polish. UK customers notice the difference — bounce rate dropped in the first month.”
★★★★★
POS + courier in one flow
“Billing, inventory, and courier labels used to live in three tools. KDF connected the stack so staff scan, ship, and track without spreadsheet gymnastics. Training took a day, not a week.”
★★★★★
6amMart customized properly
“We didn’t want the default script look. They redesigned the customer web, vendor flows, and rider app branding. Remote standups were sharp — tickets closed with screenshots, not excuses.”
★★★★★
Storefront that matches the product quality
“Category rails, hero banners, and product cards finally feel premium. They understand food e-commerce UX — not just ‘another Woo template’. Highly recommend for US-facing shops.”
★★★★★
Payments wired end-to-end
“Card and wallet flows were tested properly before go-live. Documentation was tidy enough for our UK finance lead. Rare to get both design taste and integration discipline.”
★★★★★
Customer + rider apps shipped together
“One team owned Flutter apps, admin panels, and store publishing. We iterated weekly. If you need remote engineering that respects US release cadence, they’re a strong partner.”
★★★★★
UI redesign lifted trust signals
“Trust bars, delivery messaging, and mobile nav were rebuilt with conversion in mind. Looks modern without going ‘AI purple’. Our UK ads finally land on a page we’re proud of.”
★★★★★
6Valley without the stock look
“Admin, seller, and customer panels were customized to our brand. Support after launch has been responsive on WhatsApp — important when you’re operating on US hours.”
★★★★★
Clear process from brief to go-live
“Requirement → redesign → build → store launch. No mystery phases. We’d hire them again for the next marketplace module. Professional remote delivery for North America.”
