Five disciplines. One team.

Athen's engineers work across the full product surface — from consumer interfaces to high-throughput APIs and real-time multiplayer systems.

Web Development

Marketing sites, dashboards, and web apps that load fast, hold up under traffic, and don't decay over time.

Next.js (App Router) + React + TypeScript · WordPress (headless or classic) · Tailwind CSS on a tokenized design system · Sanity, Payload, or Contentful for content · Vercel, Cloudflare Pages, or self-hosted Docker · Playwright for end-to-end, Vitest for unit

Start a project

We build modern web products on React and Next.js, from one-page launches to internal tools that real teams use every day. Pages render fast, the codebase reads cleanly, and your engineers can extend it the day we hand over. Accessibility (WCAG AA) and SEO are wired in from the first commit, not bolted on before launch.

What good looks like

Lighthouse ≥95 on the routes that matter, zero violations on axe-core, a fully typed API surface, and a README a new engineer can use to ship a feature on day one. If we would not deploy it on a Friday afternoon, it is not done.

Mobile Development

iOS and Android apps that respect platform conventions, work offline, and reach the store on the first submission.

React Native with Expo (managed or bare workflow) · EAS Build / EAS Update · Supabase, Firebase, or a custom backend · Sentry for crash reporting · TestFlight and Play Console internal testing

Discuss this project

We ship cross-platform mobile apps that behave the way users expect — smooth scrolling, real offline support, push that actually delivers, and a permissions story that does not get the app rejected. Store submission, signing, and release pipelines are part of the deliverable, not somebody else's problem.

What good looks like

60fps interactions on three-year-old hardware, deterministic offline behaviour, crash-free sessions above 99.5%, and approval on the first store submission rather than the third.

Backend & APIs

REST and GraphQL services, data pipelines, and the boring infrastructure that decides whether your product stays up at 3am.

Node.js (Fastify, Hono, Express) · PostgreSQL with Drizzle or Prisma · GraphQL via Apollo / Yoga, or REST with OpenAPI · Redis, BullMQ, or Temporal for background work · OpenTelemetry feeding Grafana or Datadog · Docker on Fly.io, AWS, or your existing platform

Discuss this project

We design backends with the same care as the frontend the user sees: typed contracts, predictable latency under load, real metrics and logs, and migrations that will not lock your database in production.

What good looks like

P95 latency budgets defined and met under realistic load, a runbook that maps every alert to a concrete action, and a deploy pipeline that anyone on call can roll back without paging us. Boring backends are good backends.

Game Development

Game Development — S&box

PC games built in S&box (C#) — original gameplay, custom systems, networked multiplayer, and shipped builds players actually finish.

S&box (Source 2 / C#) — single-engine focus · Custom gameplay systems and networked multiplayer · In-engine tooling and editor extensions · Distribution via S&box and Steam Workshop · Telemetry and crash capture for live builds

Discuss this project

We focus on S&box, Facepunch's modding-first PC engine in C# — and only S&box, only Windows PC, on purpose. Deep engine knowledge produces better games than spreading a small team across five tooling stacks.

What good looks like

A stable 60fps in normal play, networked multiplayer that behaves predictably under packet loss, a content pipeline your designers can use without us, and a build that survives a public playtest.

Full-Stack

Full-Stack Product Builds

One Athen team owning database, API, web, and mobile — so you ship features instead of coordinating between vendors.

Next.js + React + TypeScript on the frontend · Node.js for APIs, PostgreSQL for data · React Native when mobile is in scope · Sanity or Payload for content · Vercel + Fly.io or AWS, with CI/CD wired up before launch · Sentry and OpenTelemetry on a unified dashboard

Discuss this project

Most product delays happen at the seams between teams. When the same engineers own the schema, the endpoint, and the screen that consumes it, those seams disappear and decisions move at the speed of one team.

What good looks like

A working product in real users' hands by the agreed milestone, a clean handover document, and an in-house team that can ship the next feature without our involvement. We measure success by what your team can do six months after we leave.
