Hard skills
A senior-level coding test on your stack. Senior, architect or lead, we measure real coding ability.
Every stack, one process
Grouped by what the role does. Every page below is written for the person doing the hiring.
Backend and APIs
Services, integrations and the data layer your product runs on.
Java
Spring Boot, Hibernate, JUnit, Maven. APIs, migrations and performance work.
See the page →Node.js
TypeScript services, REST and event-driven APIs, testing that runs in CI.
See the page →Python
Backends, data pipelines and integrations with tests and type hints.
See the page →PHP
Platforms you need to extend, upgrade or modernize without a rewrite.
See the page →Front end
The interface your roadmap promised, in the framework your team already uses.
JavaScript
The language rather than one framework: TypeScript, performance and shared tooling.
See the page →CSS and UI
Design systems, responsive layouts, and accessibility that passes an audit.
See the page →React
Frontend engineers who ship the UI your roadmap promised.
See the page →Angular
Large typed front ends, RxJS, and upgrades from old Angular versions.
See the page →Vue.js
Vue 3 and Nuxt product UI, Pinia, and migrations off the Options API.
See the page →Mobile
Cross-platform or fully native, shipped to the App Store and Google Play.
Cross-platform
One code base to both stores, with the native side handled when it has to be.
See the page →Native mobile
Swift and Kotlin in the platform idiom, for products where native is the point.
See the page →Flutter
One Dart code base shipped to both stores, with tests and releases.
See the page →React Native
Shared TypeScript code for iOS and Android, with the native side handled.
See the page →Android and Kotlin
Kotlin and Jetpack Compose, with Play Store releases handled.
See the page →iOS and Swift
Swift, SwiftUI and UIKit, from the code to App Store review.
See the page →Infrastructure and AI
The layer underneath the product: the pipelines and cloud it runs on, the reliability it needs, and the AI features going on top.
DevOps and Cloud
AWS, Terraform, Kubernetes and pipelines your team can trust.
See the page →Platform engineering
Internal platforms, golden paths and self-service environments teams actually use.
See the page →Site reliability engineering
SLOs, on-call people can survive, and postmortems that change something.
See the page →AI engineering
RAG, agents and evals on top of foundation models, inside software you already run.
See the page →What every stack page gives you
The same four things, on every page. It is the hiring brief we would write for that role, published.
What we test for
The frameworks, libraries and tooling the role actually needs, listed so you can check them against your brief.
Typical work
What a developer on that stack picks up in the first sprints, from APIs and migrations to releases.
The coding test
The senior-level exercise we score on that stack, described before you see a single profile.
Five interview questions
The questions we use in our own rounds, with what a strong answer covers. Reuse them in yours.
We don't guess. We measure.
Every developer passes three scored checks before you ever see the profile.
Soft skills
Feedback, async communication, teamwork. No lone wolves.
English
A standardized assessment, because your standups run in English.
We test. Then we match. No "culture fit" vibes. Just data. How we vet
Pricing
One monthly price per developer. Everything in it.
No deposit, no minimum term, no placement fee. You pay one invoice a month for each developer on your team.
Senior developers from
$6,900 /month
Per developer, all-in. Your quote arrives by email with your exact number after you send the brief.
- Developer pay, local payroll and taxes
- Vetting: coding test, soft skills, English
- Free replacement within 90 days
- A direct line to our CEO
What changes the price
- Seniority and role. Senior engineer, tech lead or architect.
- Stack. Some stacks and niche tools cost more to staff.
- Team size. Larger teams get a better monthly rate per seat.
- White-label. Agencies reselling under their brand get partner pricing.
Terms in plain words
- First 2 weeks risk-free: if it isn't working, you don't pay for them
- Month to month, 30 days' notice to end
- No deposit and no minimum number of seats
- Want to hire the developer full-time? Buyout of 3 months' fee in year one, 2 months' after
