Engineering for products that are expected to grow.

Six capabilities, one team. Most engagements use two or three of them together — an app and the platform underneath it, or a modernization with a performance mandate attached.

01

Mobile applications

Native-quality iOS and Android products, shipped from one codebase without the usual compromises.

We build production mobile apps in React Native and Swift/Kotlin where it matters. Offline-first data layers, background sync, push, biometrics, and release pipelines that get a build into TestFlight and Play internal tracks on every merge.

  • React Native or fully native builds
  • Offline-first sync and conflict resolution
  • Automated store releases via Fastlane
  • Crash, ANR, and performance instrumentation
02

Web platforms

Fast, accessible product surfaces and dashboards that stay maintainable past version one.

Next.js and TypeScript front ends backed by typed APIs. We treat Core Web Vitals, accessibility, and bundle budgets as acceptance criteria, not cleanup tasks — so the product still feels quick after two years of feature work.

  • Next.js App Router architecture
  • Design systems and component libraries
  • WCAG 2.2 AA accessibility passes
  • Performance budgets enforced in CI
03

Cloud and platform services

The APIs, data pipelines, and infrastructure that carry your product when traffic arrives.

Service design, API contracts, event pipelines, and infrastructure as code on AWS or GCP. We size for the load you actually have, with a clear path to the load you are planning for — and we leave the runbooks behind.

  • REST and GraphQL API design
  • Event-driven and queue-backed workflows
  • Terraform-managed environments
  • Observability, alerting, and runbooks
04

Modernization and rescue

Strangling legacy systems incrementally, while the product keeps shipping to customers.

Inherited a codebase nobody wants to touch? We map it, put tests around the load-bearing parts, and migrate service by service. No eighteen-month rewrite, no feature freeze.

  • Architecture and risk assessment
  • Incremental strangler-fig migration
  • Test harnesses around legacy paths
  • Team handover and documentation
05

Performance and reliability

Finding the ceiling before your users do, then raising it where it counts.

Load modelling, profiling, query tuning, and caching strategy. We instrument first so decisions come from traces and flamegraphs rather than intuition, then fix the handful of things actually holding the system back.

  • Load and soak testing
  • Database and query optimization
  • Caching and CDN strategy
  • SLOs with meaningful alerting
06

Security and compliance

Practical hardening and audit readiness, built into delivery instead of bolted on later.

Threat modelling, authentication and authorization review, dependency and secrets hygiene, and the evidence trail SOC 2 or ISO 27001 auditors ask for. Controls that engineers can live with day to day.

  • Threat models and security review
  • AuthN/AuthZ architecture
  • Supply-chain and secrets hygiene
  • SOC 2 / ISO 27001 readiness support
Engagement models

Three ways to work with us.

Pick the one that matches how much certainty you have. Moving between them mid-engagement is normal and does not require renegotiating everything.

Discovery sprint

Best when the scope is still fuzzy

A fixed-price, one-to-two week engagement that ends with an architecture, a delivery plan, and a costed roadmap you own.

  • 1–2 weeks
  • Fixed price
  • Written architecture and estimate
Talk it through

Product team

Most common

Best for building or rebuilding a product

A cross-functional squad — engineering, design, and delivery — working in two-week iterations against your roadmap.

  • 3–6 months, rolling
  • Dedicated squad of 3–6
  • Shared board and weekly demos

Embedded engineers

Best when you have a team already

Senior engineers working inside your process, your repos, and your standups — filling a specific capability gap.

  • Monthly rolling
  • Your tooling and rituals
  • 30-day notice
Talk it through
Process

What the first ninety days look like.

  1. 01

    Discovery

    One to two weeks mapping constraints, users, and the systems already in play. You get a written architecture and delivery plan whether or not we build it.

  2. 02

    Architecture

    Data model, service boundaries, and interface contracts agreed up front — the decisions that are expensive to reverse once code exists.

  3. 03

    Delivery

    Two-week iterations against a visible board. Working software in a real environment from the first sprint, not a demo at the end.

  4. 04

    Scale and handover

    Load testing, observability, runbooks, and pairing with your team until they own it outright. We are meant to become optional.

FAQ

The questions we get asked first.

How quickly can you start?

Discovery sprints usually begin within two weeks. A full product team typically needs three to four weeks of notice, depending on the shape of the work.

Who owns the code and infrastructure?

You do, from the first commit. Work happens in your repositories and cloud accounts wherever possible, and everything transfers on request without conditions.

Do you work with existing in-house teams?

Yes. We can embed in your process, or own a specific service alongside your team — whichever leaves a cleaner boundary.

How do you price work?

Discovery is fixed price. Delivery is a monthly rate per squad, billed in advance, with a 30-day notice period. No change-request theatre for ordinary scope adjustments.

What happens after launch?

A smaller support arrangement for the first few months is available if you want one. Handover — docs, runbooks, pairing — is part of delivery either way.

Not sure which of these you need?

Describe the problem in a paragraph. We will tell you which capability it actually calls for — and say so if it is not us.
