## Where most teams are

Next.js and React are the frontend for many of the custom products we build. A senior engineer joins your codebase, your standups and your Slack, and ships features every week, month to month, without a months-long hiring process.

The roadmap is ahead of the team → A senior engineer in your standups

Pages got slow as the app grew → Performance work on what users feel

Nobody owns the frontend architecture → Architecture calls, made and written down

Hiring a senior dev would take months → Starts within a week, no hiring cycle

## What our Next.js developers do

### Ship product features

Dashboards, onboarding, billing screens, admin tools: the everyday work of a product team, built by engineers who have shipped SaaS, marketplaces and AI products.

### Make it fast

We split the code by route, lazy-load and compress images and prefetch the routes people use most, so pages load fast on real phones, not just on a developer's laptop.

### Full stack when you need it

Auth, APIs, Postgres or Supabase, Stripe and the integrations behind the screens. The same engineer works on both sides, so features never stall at a handover.

### Web and mobile

React skills carry over to mobile. When a product needs a mobile app as well as a web app, the same team builds both on one backend, so features reach both together.

## How it works

1. 01

### Pick a tier

Part-time, dedicated or embedded, from $4,000 a month. Tiers differ in hours and in how closely we work with your team.
2. 02

### Onboard fast

No hiring cycle and no months-long ramp: a senior engineer gets into your codebase and joins your standups, Slack and tools.
3. 03

### Ship every week

Features, performance and maintenance. The engineer doing the work is the one on your calls. Change tier or stop any month.

We came to Zeroic for one fixed-scope build and never left. Shankar Prasad built the AI into WordUp and kept finding more worth shipping - we doubled our retainer hours inside the first month. He tells us what's worth building before he builds it.

FAQ

## Frequently asked questions

How much does it cost to hire a Next.js developer?

Our retainers start at $4,000 a month for the part-time tier, month to month. Dedicated and embedded tiers add more hours. Prefer a fixed scope? We also do fixed-price projects, and audits from $1,000.

How quickly can someone start?

Within a week of agreeing the tier. There is no hiring cycle and no months-long ramp.

Do your developers work in our codebase and tools?

Yes. They work in your repository, your Slack and your standups, and follow your conventions. You review their pull requests like anyone else on the team.

Can you take over a Next.js app built with an AI tool?

Yes. Apps built with Lovable, Bolt or Cursor often need auth, data access and tests fixed before they can grow. We do that on a retainer, or as a fixed-price Code Rescue.

Do we own everything you build?

Yes, 100%. You own the code, infrastructure, docs and credentials.
