— Three tracks · one delivery model

Pick a surface. Or every surface.

We run web, mobile, and custom software on the same release rails — one team, one repo strategy, one set of standards. No hand-offs between vendors.

Track 01

Web platforms

Multi-tenant SaaS, dashboards, admin consoles and customer portals. React 19, TanStack, edge-rendered on Cloudflare with sub-100ms TTFB.

  • React + TanStack Start
  • Edge SSR · <100ms TTFB
  • RLS + audit logs
  • Design-system first
Track 02

Mobile apps

Native iOS and Android, or cross-platform when it fits. Offline-first sync, push, biometrics — built for users on the move with bad signal and big stakes.

  • Swift / Kotlin / RN
  • Offline-first sync
  • Push + deep links
  • TestFlight in 48hr
Track 03

Custom software

Internal tools, integrations, automations, AI-assisted workflows. The systems that quietly run your business — built to your domain, not a template.

  • Internal tools + portals
  • ETL & integrations
  • AI-assisted workflows
  • API-first delivery
— Release pipeline

From kick-off to kept promise.

01 / 06

Discover

We spend a week with your team and your users before we touch Figma.

02 / 06

Design

Token-first design system, accessible from day one, prototyped in real components.

03 / 06

Build

Typed end-to-end. Preview every PR. Zero broken main branches.

04 / 06

Harden

RLS, secrets, CSP, audit logs, observability — wired before launch.

05 / 06

Ship

Edge deploy, smoke tests, rollback button. The boring stuff, automated.

06 / 06

Iterate

Two-week cycles forever. Or we hand the keys to your team — fully documented.

— Deliverables

Every engagement ships with the same bar.

  • Discovery + architecture diagram
  • Component library + design tokens
