Hire senior Next.js developers
Next.js is our default stack for new web products, and this website runs on it. Our developers know where the App Router helps, where its caching surprises teams, and how to keep a large application fast.
Short answer
elitics provides senior Next.js developers from Prishtina who build and maintain App Router applications in strict TypeScript: server components, caching and revalidation, server actions with validated input, authentication and Core Web Vitals. You interview them yourself, they start about 48 hours after you approve their profiles, and team extension costs €45–65 an hour.
- per engineer-hour on month-to-month terms
- €45–65
- to start after you approve the profiles
- ~48 h
- server components, streaming and server actions
- App Router
- no any in production code, Zod at the boundaries
- Strict TS
What our Next.js developers build
- SaaS applications
- Dashboards, account areas and admin tools with authentication, roles, billing and multi-tenant data.
- Marketing sites that rank
- Static and incrementally regenerated pages with a headless CMS, structured data, sitemaps and multi-language routing.
- Headless commerce
- Storefronts on top of a commerce API, with fast product pages and server-rendered search.
- Pages Router to App Router migrations
- Route-by-route moves that keep the site live, with both routers running side by side until the last page is moved.
What a senior Next.js developer should own
The framework makes many decisions for you. A senior developer knows which defaults to keep and which to override.
- Rendering choices
- Static, dynamic or streamed per route, based on how fresh the data must be and how much it costs to render.
- Caching and revalidation
- Which fetches are cached, how tags and paths are revalidated after a mutation, and how to stop users from seeing stale data.
- Server actions done safely
- Input validated on the server with a schema, authorisation checked in the action itself, and errors returned in a form the UI can show.
- Performance budgets
- Less client JavaScript through server components, images and fonts handled by the framework, and Interaction to Next Paint tracked in production.
Questions to ask a Next.js developer
Good candidates answer with trade-offs, not with the framework documentation.
- 01
When would you render a page statically, and when dynamically?
Static for content that changes on publish, with revalidation; dynamic for per-user or real-time data. A strong answer mentions streaming slow parts behind Suspense.
- 02
A user updates a record and still sees the old value. Why?
Cached fetch or full-route cache not revalidated. Look for revalidateTag or revalidatePath after the mutation, and an understanding of the client router cache.
- 03
Where do you check permissions in a server action?
Inside the action, on every call. A hidden button is not a permission check, because server actions are public endpoints.
- 04
How would you move a large app to the App Router?
Incrementally: shared layout first, then low-risk routes, with both routers live. Data fetching and auth helpers are rewritten once and reused.
- 05
Our dashboard feels slow on clicks. Where do you look?
Interaction to Next Paint in field data, heavy client components, long tasks during hydration, and state updates that re-render large trees.
How hiring an engineer works
- 01
Tell us the role
Stack, seniority, start date and the hours you need to share. A call with our engineering lead takes 30 minutes.
- 02
Review profiles
You receive engineer profiles matched to your stack and interview the ones you choose.
- 03
Start in about 48 hours
NDA and IP assignment are signed, and the engineers are set up in your repositories and tools.
- 04
Two-week trial
If you are not satisfied, you do not pay for those two weeks. An engineer who is not the right fit is replaced at no extra cost.
Typical set-ups
- One developer in your team
- A senior Next.js developer joins your sprints and code review, usually to add capacity or bring App Router experience.
- Front-end pair
- Two developers who take one product area end to end, from design handover to production.
- Full-stack squad
- Next.js developers with a back-end engineer and QA, for a new product or a rebuild.
Ways to work with us
Dedicated squad
A cross-functional team (product, engineering, QA, DevOps) that owns a product or feature.
Best when
You want a product built or rebuilt without growing headcount.
Build-Operate-Transfer
Your own development center in Kosovo, set up and run by us.
Best when
You plan a long-term engineering presence in Europe.

Common questions
Do your Next.js developers only deploy to Vercel?
No. Vercel is our default for new projects, but we also run Next.js on AWS, Google Cloud and Cloudflare, in Docker where your platform team requires it.
Can they work in our existing codebase and conventions?
Yes. They work in your repositories, follow your conventions and go through your code review. Our own default stack is used only for new projects.
What else is in your default web stack?
Next.js with TypeScript and Tailwind CSS, Supabase for Postgres, authentication and storage, and Vercel for deployment. We change it when your hosting, compliance or existing systems call for something else.
Is there a trial period?
Yes. New team extension engagements start with a two-week trial. If you are not satisfied, you do not pay for those two weeks, and we replace an engineer who is not the right fit at no extra cost.
