Web apps built to be run, not just launched
Next.js and React products with typed APIs, real auth, and hosting that costs cents while you are small.
How we build
Architecture comes before code. We map the data, the roles, and the one or two flows that must never break, then choose the simplest stack that carries them: Next.js on the front, Postgres behind it, and a queue only if the product needs one.
Deploys go through preview environments on every pull request, so you review real URLs instead of screenshots.
Architecture that scales down too
The diagram is the shape most products grow into: a gateway, a load balancer, stateless API workers, a managed database, and monitoring. We start with the minimum and add pieces when metrics ask for them, which keeps your first year of hosting in the low hundreds of dollars.
Typed at the boundary
Every request body is validated before it touches the database. A bad payload returns a clear 400; nothing partial is written. This is the handler pattern we use across client projects.
import { NextResponse } from 'next/server'
import { z } from 'zod'
import { db } from '@/lib/db'
const User = z.object({
email: z.string().email(),
role: z.enum(['user', 'admin']),
})
export async function POST(request: Request) {
const parsed = User.safeParse(await request.json())
if (!parsed.success) {
return NextResponse.json({ error: parsed.error.flatten() }, { status: 400 })
}
const user = await db.users.create(parsed.data)
return NextResponse.json(user, { status: 201 })
