Services

Everything it takes to ship and run serious software.

A senior team, a disciplined process and a track record in production. Bring us a product to build, a system to fix or a decision to make.

01

Product engineering

We take products from idea to launch and keep improving them after. You get a typed, tested codebase you own outright, built by people who have already solved the problems you're about to hit.

  • Next.js and React front ends
  • APIs, background jobs and real-time features
  • Two-sided marketplaces and multi-tenant SaaS
  • Admin, moderation and internal tooling

02

Payments & commerce

Payments are where small mistakes get expensive. We design money flows with idempotency, reconciliation and audit trails from day one, because we run them in production ourselves.

  • Stripe integrations and webhooks
  • Escrow, wallets and seller payouts
  • Subscriptions and invoicing
  • Fraud, disputes and reconciliation

03

AI integration

We add AI where it earns its place: features your customers use, and automation that removes manual work from your team. Every feature ships with evaluation, guardrails and cost controls.

  • Assistants, search and summarization
  • Workflow automation
  • Document and data extraction
  • Evaluation, guardrails and cost control

04

Infrastructure & security

We harden what you have or build it right the first time: authentication, access control, edge security, performance and monitoring, so problems surface before your customers notice them.

  • Authentication and access control
  • Cloudflare, Vercel and AWS
  • Performance, Core Web Vitals and SEO
  • Monitoring, alerting and incident response

How every engagement runs.

The same three steps whether we're building a product from scratch or hardening one you already have.

  1. 1

    Specify

    We turn your goals into a written specification with clear scope, milestones and acceptance criteria. You know exactly what you're getting before we write code.

  2. 2

    Build

    We ship in small, tested increments you can review every week. Senior engineers make every decision and review every change before it ships.

  3. 3

    Run

    We launch, monitor and keep improving what we build. We operate our own products the same way, so production is where we're most at home.

Ways to work with us.

Fixed-scope projects

A defined outcome, a written spec and a delivery schedule. Best for new products, rebuilds and well-understood features.

Ongoing partnership

A monthly engagement for teams that need senior engineering capacity: new features, maintenance and technical leadership.

Technical advisory

Architecture reviews, security and performance audits, and a second opinion before you commit to a big decision.
