Services

What we do, end to end.

We help product teams design, build and ship mobile and web applications — and we stick around to make them better.

Offerings

Four ways we plug in.

Pick one or stitch them together. Most of our partnerships start with a single product and grow from there.

Start a project
  • 01

    Cross-platform mobile apps

    One codebase, two stores, real native feel. React Native and Expo, used by people who actually know where the edges are.

    • React Native (new architecture) + Expo
    • Native modules in Swift / Kotlin where needed
    • App Store & Play Store release pipelines
    • Push, analytics, crash reporting, OTA updates
  • 02

    Native iOS & Android

    When the product demands native performance, deep platform features, or hardware integrations, we go straight to Swift and Kotlin.

    • Swift / SwiftUI for iOS
    • Kotlin / Jetpack Compose for Android
    • Bluetooth, camera, sensors, background tasks
    • Performance-critical screens & SDKs
  • 03

    Web applications

    Marketing sites, dashboards, internal tools, full SaaS. React, Next.js, and a no-nonsense TypeScript codebase your team will still like in a year.

    • React + Next.js (App Router)
    • TypeScript end-to-end
    • Design systems & component libraries
    • Edge-ready deployments on Vercel
  • 04

    Engineering consulting

    Stuck on architecture, performance or hiring? We embed with your team and help you move forward with fewer regrets.

    • Codebase & architecture reviews
    • React Native upgrades and new architecture migrations
    • Performance & bundle-size audits
    • Hiring support and tech interviewing

Capabilities

Everything a product needs.

One team, one accountable result. No handoffs to invisible departments — design, engineering and delivery sit at the same table.

  • Discovery & product strategy
  • Wireframes & prototypes
  • UI design & design systems
  • iOS & Android engineering
  • Web engineering
  • API & backend integration
  • QA & release management
  • Analytics & observability
  • Performance audits
  • Code & architecture reviews
  • Team enablement & training
  • Long-term maintenance

How we engage

Three ways to work with us.

Fixed scope

Project delivery

Clear goals, scoped milestones, fixed timeline. Best when you know what you want and need someone to ship it.

Open scope

Product team

We act as your product team — design, engineering, releases — month to month. Best for early-stage products that need to learn fast.

Focused

Specialist sprint

1–4 weeks, one specific outcome: an audit, a migration, a hard problem solved. Best when you need senior help, fast.
