# Full-Stack Web Development

> Full-stack web development services: one team owning frontend, backend, and the integration between them, from data model to deployment. By Sentient Arc.

End-to-end web product engineering under one team: the frontend, the backend, and the seam between them owned together, so the product holds where most builds crack.

## Products break at the seams
Split a build across a frontend shop and a backend shop and the defects collect in the gap between them: mismatched contracts, states nobody owns, and a launch that stalls in integration.

Each side ships something that works in isolation and points at the other when it does not. The product is only as coherent as the seam holding the two halves together.

## One team across the whole stack
We own the round trip end to end: the interface, the API it calls, and the contract between them designed as one thing, so there is no gap to fall through and no one to point at.

The deployment pipeline ships with the product: environments, CI checks, and monitoring from the first sprint, so the hundredth release is as uneventful as the first.

## What we build
- **End-to-end features**: Whole features owned from interface to database, shipped as one slice instead of handed across a boundary.
- **Frontend-to-backend contracts**: Typed, shared contracts between the client and the API, so the two halves evolve together instead of drifting.
- **Admin & internal tools**: The operational surfaces behind the product: dashboards, permissions, and workflows your team runs on.
- **Pipelines & environments**: Build, preview, and production environments with CI checks and monitoring, delivered as part of the product.

## Stack
- **Frontend:** React, Next.js, TypeScript, Tailwind CSS
- **Backend:** Node.js, Nest.js, Express.js, Django, Ruby on Rails
- **Infra:** Postgres, Redis, Vercel, AWS, CI/CD

## FAQ
**When should I hire one full-stack team instead of separate frontend and backend teams?**

When the product is one system, not two. A single team owning both sides removes the integration gap where most delays and defects collect, and keeps the client and API contract moving together.

**Which stack do you build on?**

The core is React and Next.js over Node or Python services, with Postgres as the default system of record and Vercel or AWS underneath. Beyond that core we choose per project: Nest.js, Django, or Rails where the domain or the team calls for it.

**Do you rebuild or extend what we have?**

Whichever the codebase deserves. We audit first: many products need a strangler-pattern extension and a paved deployment path, not a rewrite, and we will say so when that is the cheaper truth.

**Can you join an existing team on part of the stack?**

Yes. If you already have strong frontend or backend coverage, we can own the other half or the integration layer, though the fewest surprises come when one team holds the whole round trip.
