To hire full-stack developers, look for seniors who own a feature end to end: data model and migrations, API, front end, authentication, payments, deployment and monitoring. In 2026 that usually means TypeScript with React or Next.js, a Node.js, Java or Python backend, Postgres or MongoDB, Docker and CI. Yarify provides senior full-stack engineers monthly with 2 weeks' notice, or as fixed-price builds.
Three specialists vs one full-stack senior
Split by layer
- Front end waits on backend
- Backend waits on DevOps
- A two-day feature takes two weeks
- Context lost at every handoff
One owner per feature
- Decisions made in minutes
- Schema, API and UI change together
- Preview URL per pull request
- Monitoring shipped with the feature
One engineer, every layer
-
Data model
Migrations safe on a live database.
-
API
Node.js, Spring Boot or Python.
-
Front end
Next.js or React, shared types.
-
Auth and payments
Roles, SSO, Stripe webhooks.
-
Deploys
Docker, CI, Cloud Run.
-
Monitoring
Logs, errors, analytics events.
Built by people who knew every layer
Our content automation platform pairs a Spring Boot backend with a Next.js front end, MongoDB and OAuth into five publishing platforms. It runs on about an hour of maintenance a month.
Full-stack has limits. Deep search or heavy data platforms may need specialists like our Java or Next.js developers. We'll say so on the first call.
Hiring takes months. We start building.
Hiring a developer
- Job post & sourcing
- Interviews
- Notice period
- Onboarding
- Building
Yarify
- Call + fixed quote
- Building + weekly demos
- Live. Iterating with users.
Illustrative timeline. In-house hiring usually spends months on sourcing, interviews and notice periods before the first commit.
Three ways to hire full-stack developers
-
Staff augmentation
A senior joins your team and ships whole features. Monthly, 2 weeks' notice.
-
Dedicated team
No CTO in-house? A small team owns the product and explains trade-offs in plain language.
-
Fixed-price MVP
A written scope and fixed quote for an MVP build. Overruns on our estimate are ours.
What a senior full-stack developer does
- Starts from the data model and user flow, not the component library
- Checks permissions on the server, never only in the UI
- Shares types or schemas between API and front end
- Sets up CI and deploys without a DevOps engineer
- Writes a design note before touching money or permissions
- Says when a specialist is needed
Interview questions for full-stack developers
-
Walk me through a feature, database to deploy.
Decisions at every layer: schema, API shape, UI states, rollout, monitoring. Gaps in the story are gaps in ownership.
-
A page shows another customer's data. Where?
Server-side authorization, a wrongly keyed cache, shared global state. A stop-everything bug.
-
When does work leave the request?
Anything slow, flaky or retryable: emails, imports, AI calls. Plus how users see progress.
-
What would you not build yourself?
Auth, payments, email delivery and search are often better bought. Seniors know build vs buy.

Questions buyers ask us
How much does it cost to hire a full-stack developer?
Industry surveys put senior developers at about $60–80 per hour in Central and Eastern Europe, $110–160 in Western Europe and $140–200+ in the US. A senior CEE month is roughly $9.6k–12.8k. We quote monthly or fixed-price after a free call.
Is one full-stack developer enough?
For a new product, one senior full-stack developer often ships more than two juniors split by layer. As it grows, add a second engineer for review and continuity. A small dedicated team gives you that without hiring.
What stack do your full-stack developers use?
Most often Next.js and TypeScript up front, with Node.js, Java Spring Boot or Python behind, Postgres or MongoDB, Docker and CI. We work in your existing stack and only suggest changes that solve a real problem.
Can a full-stack developer build our MVP?
Yes. Many of our MVPs are built by a senior full-stack engineer with a second engineer reviewing. You get a written scope and a fixed quote; overruns on our own estimate are our cost. See the MVP scope checklist.
We have no CTO. Can you still work with us?
Yes, that's what a dedicated team is for. We own technical decisions, explain trade-offs in plain language, show working software every week and document everything so a future CTO can take over.
Who owns the code?
You do, from day one. The engineer commits to your repository, infrastructure runs in your cloud account and the contract assigns all IP to you. End the engagement with 2 weeks' notice and keep everything.
