Qiao
An AI relocation app for international students, launching first in China.
Flutter Dart Go
An independent digital product studio. We design and engineer web platforms, mobile apps and MVPs for startups and software teams, from first scope to launch.
What we do: Web platforms, Mobile apps, Web3 & blockchain, Product design. An MVP in weeks, not months.
Boring where it should be boring, sharp where it matters. Proven technology at the foundation, the interesting risks where your users will feel them.
Marketing sites, SaaS products and internal tools. Server-rendered, fast, and built to be found - SEO is part of the build, not an add-on.
3-8 weeks(02)Cross-platform when speed to market wins, native when the product demands it. We ship our own Flutter app, so yours is built by people who live in this stack daily.
6-12 weeks(03)Smart contracts, DeFi protocols and the web2 half most crypto teams underestimate. Security review is the default, not an option.
4-10 weeks(04)Research, UX prototypes, design systems and identity. Designed and engineered by the same team, so what you approve in Figma is what ships.
2-6 weeksShipped and shipping from our own roadmap. The process your project gets is the one we bet our own money on.

Boring where it should be boring, sharp where it matters.
The principle behind every technology choice we make.
The number you sign is the number you pay. No hourly meters, no surprise invoices.
A one-week deep dive turns your brief into a written, fixed feature list.
1 weekThat list gets a fixed price and a fixed timeline before anyone writes code.
Signed scopeWeekly builds you can run yourself. Design, code and infrastructure under one roof.
Ship weeklyAnalytics, monitoring and a deployment pipeline. Clean keys and docs, stay or hand over.
Yours to keepWe take you from a rough spec to a live product - strategy, design, engineering and the infrastructure it runs on - then hand over clean keys and documentation. You talk to the people writing the code, not an account manager.
Start a projectWe slot in as a delivery team under your brand: NDA by default, your name on everything, no contact with your clients. Overflow sprints, whole features or entire builds - scoped and priced the same fixed way.

Full storySomething else on your mind? hi@duor.digital
A digital product studio takes a product from an idea to something running in production: research, product design, frontend, backend, infrastructure and release. One team owns all of it, which is the difference between a studio and hiring a designer, an agency and a contractor separately.
It depends on scope, and we quote scope rather than hours. A one-week discovery turns your brief into a written feature list, and that list gets a fixed price and a fixed timeline before anyone writes code. Send a rough brief to hi@duor.digital and you get a number back.
A marketing site ships in three to five weeks. A mobile app or a SaaS MVP is usually eight to twelve weeks from discovery to store or production, depending on how much of the backend is new.
Yes, and a good share of our work is exactly that. We take on overflow, whole workstreams and specialist pieces such as Flutter, 3D and WebXR, or Go services, either white label under your brand or as a named subcontractor.
Three of them. Qiao is an AI relocation app for international students, built in Flutter and shipping to both stores. Duor Configurator is a 3D furniture design tool that runs in the browser and shows the result at full size in AR. Duor Radio is an internet radio player for iOS and Android that keeps playing through a dropout on a downloaded backup playlist. The habits we use on our own products are the ones your project gets.
TypeScript, Next.js and React on the web, Flutter for cross-platform mobile with Swift and Kotlin where a product needs native, Go and Node.js on the backend, PostgreSQL and Redis for data, Three.js and WebXR for 3D and AR, and Solidity or Rust for web3.
We are a distributed team and we take projects worldwide, in English or Russian. Overlap is agreed at the start: for most clients that means at least four hours a day of shared working time.
Every engagement hands over analytics, monitoring and a deployment pipeline, so your team can keep shipping without us. When you would rather we stayed, we continue on a monthly scope.
Two sentences about what you’re building is enough. We come back with questions, a rough estimate and the earliest start date.
