How engagement works

As your React Native agency, we run a shared backlog, design reviews, and engineering sprints, and you keep one point of contact throughout.

  1. 01

    Discover

    Goals, constraints, data sources, and success metrics, all settled before we touch architecture or prompts. The work for teams in New York stays tied to the outcome you asked for.

  2. 02

    Design

    System design, AI/tool boundaries, interface direction, and interaction prototypes. You see progress on the critical path every week.

  3. 03

    Build

    Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. Nothing here waits on a handover between separate teams.

  4. 04

    Launch

    Ship, monitor, harden, and keep improving models, tools, and product after go-live. On React Native app development projects we favour practical architecture over trendy defaults.

How we build it, and why

The stack is chosen per project, not applied from a template. For React Native agency work these are the defaults, and the reason each one is on the list.

React Native
one codebase for iOS and Android, which halves the surface area you maintain after launch
Expo
over-the-air updates and managed builds, so shipping a fix does not mean waiting on app store review
TypeScript
types across the whole stack, which catches the class of bug that only shows up in production
Firebase
auth, push, and realtime sync without standing up your own infrastructure first
NestJS
structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers

What the first weeks look like

  1. Week 1

    Scope and architecture

    Users, data, integrations, and constraints, ending in a written plan for the React Native app development that you approve before anyone opens an editor.

  2. Weeks 2-3

    Design the critical path

    The screens that carry the product, prototyped and clickable. Design and engineering review together, so nothing gets drawn that cannot ship.

  3. Weeks 4-8

    Build in weekly slices

    Every week ends with something on a real URL. ios and android apps lands early, because the rest of the plan depends on it working.

  4. Launch

    Ship, measure, hand over

    Release, monitoring, analytics, and a documented handover, so your team can carry it without calling us.

Weighing up your options

There are three realistic ways to get this built. Each is the right answer for someone.

A solo freelancer

Cheapest per hour and fine for a contained task. The risk on React Native app development is breadth — one person covering design, backend, infrastructure, and launch usually means one of them is weak, and there is no cover when they are unavailable.

A local agency in New York

Same timezone and a face to meet, which genuinely matters for some teams. You are also paying New York companies hiring on portfolio proof and production AI. rates for the whole team including the layers that never touch your React Native app development, and a local shortlist is a small shortlist.

Arcode

A small senior team. The people who scope the React Native app development write the code, you get weekly demos instead of status decks, and the engagement ends when the thing is live and handed over.

Working with teams in New York

New York companies hiring on portfolio proof and production AI. We work with clients in New York remotely and keep overlapping hours in EST/EDT. We usually collaborate in English.

How we work with New York teams

New York is on ET, so our afternoon covers your morning. In practice that means a scheduled daily window for anything that needs a conversation, and written updates waiting when you start.

What New York clients usually need

New York briefs cluster around fintech, media, and B2B SaaS. A lot of the work is replacing a prototype that got a company to revenue but cannot carry the next stage of growth.

Contracts, data, and compliance

Contracts are usually US contractor agreements with IP assignment and an NDA. Fintech projects get SOC 2 evidence and audit logging scoped into the build rather than retrofitted before a raise.
