Figma to working UI on your component library, responsive and accessible.
Data fetching and caching with TanStack Query or your setup, so screens update without full reloads.
A small set of shared components instead of copy-paste, so the next screen takes hours to build.
End-to-end tests on signup, checkout and the other flows your revenue depends on.
Why we pick React, from our tech stack guide
React is the dominant UI library for building interactive web applications. React 19 introduced Server Components, Actions, and use() — shifting toward server-first rendering.
Unmatched ecosystem: thousands of component libraries, mature state management (Zustand, Jotai, TanStack Query), and deep tooling. Powers Meta, Netflix, Airbnb, and most startups.

They build the interface of your product in React: screens, forms, state and the calls to your API. Ours use AI agents like Claude Code for most of the typing, then review and test every change.
Most engineers in the network are full-stack: Node.js, PostgreSQL and the APIs your screens need. Mention the backend in your brief and we match for both.
Some do. If you need a mobile app next to the web app, say so in the brief and we send engineers who have shipped both.
Our engineers charge $30-60 an hour, depending on experience. Full time at 40 hours a week that comes to about $5,000-10,000 a month, with no deposit and no platform fee. On Toptal the same search starts at about $60 an hour, plus a $500 deposit and $79 a month.
Every candidate builds and presents a full-stack demo project: a landing page, a web app, a backend and a database with RAG, all with AI agents. Then our CTO, Igor Krasnik, interviews them on technical knowledge, product sense, clear thinking and how they work with a team. Only engineers who pass both are matched with clients.
Yes. Pick 20 or 40 hours a week in the brief. Billing is weekly, so a 2-week fix and a year-long engagement work the same way: you stop when the work is done.
Tell us and we send a replacement from the network. There is no contract to exit and no notice period, since billing is weekly.
Yes. They join your Slack and work with you like a member of your team. There is no account manager in between, and you get a written update every day.
