[ Hire Full-Stack Developers ]
One Engineer From Database Schema to Shipped Screen
Hire senior full-stack developers who own a feature end to end: the migration, the API, the UI and the deploy. Ideal when you need product breadth before you need specialists.

When a Full-Stack Developer Is the Right Hire
Breadth pays off in these six situations. For deep specialist work, we point you to the right track instead.

Full-Stack Combinations We Staff
We match the exact pairing you run, then check both halves: a strong UI with a weak data model is not full-stack.
- InterfaceServer
JavaScript stacks
- MERN (MongoDB, Express, React, Node.js)
- MEAN (MongoDB, Express, Angular, Node.js)
- Next.js with server actions
- NestJS with React
- Remix
- FrontendBackend
Polyglot pairings
- Django or FastAPI with React
- Spring Boot with Angular
- .NET with React or Blazor
- SchemaContract
Data and APIs
- PostgreSQL and Prisma
- MongoDB and Mongoose
- Redis caching and queues
- REST, GraphQL and tRPC
- Stripe and webhooks
- BuildRun
Delivery and hosting
- Docker
- GitHub Actions
- Vercel and Netlify
- AWS and Google Cloud
- Sentry and logging
- Playwright end-to-end tests
How We Vet Full-Stack Developers
Our tests make candidates prove both halves of the stack, plus the glue between them.

- Shipped features
- Database to UI
- Depth in both halves
- Product trade-offs
Whole features shipped
End-to-end portfolio check
We look for products where they owned the schema, the API and the UI, not just one layer.
stage 1 of 4
Take-home task
Feature slice assignment
Add a feature to a small app: a migration, an authenticated endpoint, a form with validation and an end-to-end test.
stage 2 of 4
90 minutes
Stack depth interview
Data modeling, N+1 queries and caching on the server side, then state, rendering and accessibility on the client side.
stage 3 of 4
Trade-off thinking
Product judgment check
How they scope a vague request, when they cut corners on purpose and how they flag technical debt to founders.
stage 4 of 4
From Kickoff to a Feature in Production
Full-stack hires touch everything, so their first days focus on a small change that crosses every layer.
Day 1
Stack and roadmap call
A 30-minute call on your current stack, hosting, team and the next three months of features.
Within 24 hrs
Profile shortlist
Two or three engineers who have shipped with your exact frontend and backend pairing.
Day 2
Interview and choose
Meet the candidates and run your own coding round if you want one.
Within 48 hrs
First full-stack change
Local setup, staging access and a small feature merged from database to UI.

Hiring Full-Stack Developers: FAQs
Still deciding? A 30-minute call usually answers the rest.
Ask Us DirectlyFor an early product or a small team, one full-stack engineer usually ships faster because there are no handoffs. Once you have heavy real-time, data or design system work, adding specialists pays off. We can start with one and add others later.
A dedicated full-time full-stack developer starts from $3,000 a month. Senior tech leads who also handle architecture and DevOps sit higher in our range.
Yes. MERN and MEAN are two of our most requested stacks. We also staff Next.js, NestJS, Django or FastAPI with React.
For a focused MVP, often yes, especially with AI-assisted engineering. For a fixed deadline we usually suggest our MVP in 3 Weeks package from $8,000, which delivers one core journey as a live web app at a fixed price.
For most new web products we suggest Next.js with TypeScript and PostgreSQL, because one language covers both sides and hiring is easy later. If your team or AI work is Python-heavy, Django or FastAPI with React is a strong choice.
Yes, for typical setups such as Vercel, Docker on AWS or Google Cloud, and GitHub Actions pipelines. For Kubernetes, multi-region or strict compliance setups we bring in a DevOps engineer.
The take-home task needs a migration, an API endpoint and a tested UI in one change. The live interview then probes database design and frontend rendering separately, so a weak side shows up early.
Yes. They join your standups, pick up tickets from your board and follow your branching, review and release rules from day one.
