Overview

What This Covers

AI features need to live inside great products — not bolted on top of fragile ones. We build full-stack web and mobile applications that are engineered for AI from the ground up: streaming UI, agent integration, real-time feedback, and the data pipelines that keep AI features accurate. End-to-end accountability from design to production.

Included in scope

  • Full-stack web application development (React, Next.js)
  • Mobile application development (React Native, Expo)
  • AI feature engineering (streaming UI, agent integration)
  • Auth, billing, and subscription management
  • REST and GraphQL API design and development
  • CI/CD, monitoring, and production deployment

When to Engage

Situations We're Built For

"We need to build an AI product, not just add an AI feature."

We engineer the full product — UI, backend, data layer, and AI integration — as a coherent system rather than a collection of components.

"We have a backend but need a great AI-powered frontend."

We connect to your existing API and build a frontend that makes AI capabilities feel native — streaming responses, real-time updates, and intuitive UX.

"We need to ship in 8 weeks."

We scope what's achievable in eight weeks, build it, and ship it. No sprint creep, no scope inflation. A real product in your users' hands.

How We Work

Our Approach

1

Architecture and design

System design and UX aligned before writing code. Decisions made upfront.

2

Foundation sprint

Auth, routing, design system, and API client. The scaffold everything else builds on.

3

Feature sprints

Two-week sprints with demos each Friday. Stakeholders see and validate working software.

4

AI integration

LLM integration with streaming, error handling, rate limiting, and cost controls.

5

Production launch

Deployment, monitoring, error tracking, and a runbook.
