§Practice · five things

What we make.

A short list, kept short on purpose. We say no to most of what doesn't fit on it.

01Practice · web

Web.

Custom apps and sites that hold up after launch.

read more →

We build the React/Next side of your product alongside the backend it talks to. The boring tools — Postgres, Node, React (even PHP when it earns its place) — chosen because they hold up at every scale we've seen, and because the engineer you hire next year will already know them.

What we build

  • 01Custom CMSes when the off-the-shelf one starts costing you an hour a day.
  • 02Marketing sites that don't lie about what the product does.
  • 03Internal dashboards that replace the Tuesday-morning Excel ritual.
  • 04Payment, auth, and billing flows for the parts you can't get wrong.

Stack

Next.jsReactNode.jsPostgresPHP

Best for

Teams who own their product but don't want to own the agency.

02Practice · mobile

Mobile.

Native or React Native, picked honestly.

read more →

iOS and Android, written native when it matters and React Native when it doesn't. Most of what we ship is small, focused apps with a clear job — not fifty-screen behemoths that take a year to build and ten months to maintain.

What we build

  • 01Companion apps for hospitality, retail, and events.
  • 02Scanner and staff-side tools paired with a web admin.
  • 03Notification-first apps that respect a user's afternoon.
  • 04Camera, geolocation, and offline-first features done properly.

Stack

React NativeFlutterExpo

Best for

Operators with a clear mobile workflow — not 'let's also have an app' projects.

03Practice · seo-geo

SEO & GEO.

Content infrastructure for humans first, search engines second, models third.

read more →

We make sure the page is readable before we worry about whether it's crawlable. Then we make sure it's crawlable. Then we make sure the structured data tells the truth — because that's increasingly what model-driven search reads from when it answers your buyers.

What we build

  • 01Schema markup that matches what's actually on the page.
  • 02Site architecture audits and content models that don't fight the CMS.
  • 03Performance work that improves real numbers, not just Lighthouse.
  • 04Marketing copy rewritten from the ground up — we write it, you ship it.

Stack

JSON-LDOpen GraphSitemapsLighthouseRUM

Best for

Companies whose buyers find them through search — and increasingly through chat.

04Practice · custom-systems

Custom systems.

The unglamorous software that runs the business.

read more →

Internal tools, admin panels, scheduling systems, reporting layers. The kind of thing that's never in the demo but always in the daily reality. We design the data model first and let everything else fall out of it.

What we build

  • 01Admin UIs tuned to a specific team's daily flow.
  • 02Reporting layers that turn six hours of Excel into a one-glance read.
  • 03Scheduling, invoicing, and ops tooling for service businesses.
  • 04Data importers and exporters that don't need a maintenance contract.

Stack

PostgresNext.jsServer actionsBackground jobs

Best for

Operators carrying spreadsheets that should have been a tool two years ago.

05Practice · security

Security & compliance.

Security audits and PCI DSS consultancy for ASVs.

read more →

We help Approved Scanning Vendors and merchants close the gap between a passing scan and a defensible posture. PCI DSS scoping, evidence collection, scan-result triage, and remediation engineering — written by the people who'll fix the code, not just write the report.

What we build

  • 01PCI DSS scoping and gap assessments for SAQ-A through SAQ-D environments.
  • 02ASV scan triage: false-positive review, evidence packaging, dispute prep.
  • 03Application security audits — code review, threat modelling, fix patches. Reverse engineering protection.
  • 04Remediation work for findings nobody else on the team wants to own.

One conversation, no proposal deck.

Sixty minutes on the phone. We bring questions. You bring the problem. By the end, both of us know if it's a fit — usually within the first ten.
