Capabilities

What we build.

We don't do everything. We do these things well, for clients who want them done correctly the first time.

01

Web Applications

The interface your customers actually use. We build in Next.js, React, and whatever the problem demands — not whatever we already know best.

Next.js · React · PostgreSQL · Stripe · Edge functions

// Optimistic updates. Zero jank.
await mutate(data, { revalidate: false })
02

Mobile

React Native when cross-platform makes sense. Swift or Kotlin when it doesn't. We won't upsell you the wrong stack to pad scope.

React Native · Expo · iOS · Android

// One codebase. Two stores.
export default Platform.select({
  ios: IOSComponent,
  android: AndroidComponent,
})
03

AI Integration

Not "AI-powered" — actually wired up correctly. We integrate Anthropic and OpenAI APIs into real workflows with proper context management, fallbacks, and cost controls built in.

Anthropic · OpenAI · pgvector · RAG pipelines · LangChain

const res = await anthropic.messages.create({
  model: 'claude-opus-4-8',
  max_tokens: 1024,
  messages: thread,
})
04

Backend & APIs

FastAPI, Node.js, authentication, payment processing, third-party integrations. The boring infrastructure done correctly so you stop thinking about it.

FastAPI · Node.js · Stripe · Auth · REST · GraphQL

@router.post("/checkout")
async def create_session(
  body: CheckoutBody,
  user: User = Depends(get_user),
):
    return stripe.checkout.Session.create(...)
05

Data & Analytics

ETL pipelines, dashboards, real-time analytics. You can only improve what you can measure — so we make sure the measurement is accurate and fast.

PostgreSQL · ClickHouse · dbt · Metabase · Redis

SELECT
  user_id,
  date_trunc('week', created_at) AS week,
  COUNT(*) AS events
FROM events
GROUP BY 1, 2
ORDER BY 2 DESC
06

Systems Design

Architecture reviews, technical due diligence, scaling plans. We've seen what happens when these decisions get deferred — and we've cleaned up the aftermath more than once.

AWS · GCP · Docker · Kubernetes · architecture reviews

# C4 — Container View
System  --> API     : HTTPS/443
API     --> DB      : TCP/5432
API     --> Cache   : TCP/6379
API     --> Queue   : AMQP
