LUMEN&HOUSEStart a project
01 — Capabilities

One studio.
The whole stack.

Six disciplines under one senior roof — from the first commit to the growth curve after launch. No handoffs, no juniors, no lock-in.

TypeScript Next.js React Rust Go Postgres Edge WebGL Node Python

Included in every engagement

Engineering, not just delivery.

Whatever the discipline, the fundamentals don't change. You get the same senior craft, the same standards, and code you fully own.

Architecture

Decided up front

Stack, data model and trade-offs written down and agreed before we build.

Quality

Typed & tested

TypeScript end to end, tests where they earn their keep, checks in CI.

Performance

Fast by default

Budgets enforced per route; Core Web Vitals green from day one.

Handover

You own it

Your repo, your infra, documented — so any team can pick it up.

The toolkit

A stack chosen for the next five years, not the last five.

We pick boring where it should be boring and sharp where it counts.

FRONTEND

Next.js · React · TypeScript

App Router, server components and streaming — the modern React stack, used the way it's meant to be used.

BACKEND

Node · Go · Rust · Postgres

The right runtime for the job, on a database that will still be the right call at scale.

AI

OpenAI · Anthropic · pgvector

Model-agnostic pipelines with retrieval, evals and guardrails — not a wrapper around one API.

INFRA

Vercel · AWS · Cloudflare

Edge-first deploys, IaC, and observability so you can see what's happening in production.

DESIGN

Figma · Storybook · Motion

Systems built in code, documented and versioned, that scale with the product.

QUALITY

Playwright · Vitest · CI

Automated tests, visual checks and performance gates on every pull request.

Start here

Let's build the thing they can't stop using.

Send the brief. A senior engineer reads every one and comes back with an architecture, a plan and a quote written against your actual scope — usually within a day.
