Custom engineering

Product & app development

We design and build web and mobile apps, customer portals and APIs that are secure and audit-ready from the first release, for founders shipping an MVP, growing companies outgrowing spreadsheets and enterprises building customer-facing software.

01

Product discovery, UX and design systems

Know what to build before you pay to build it. We turn an idea or a painful process into a clear scope, tested designs and a design system your team can keep using.

What we deliver

  • Discovery workshops that define users, jobs to be done and the smallest release worth shipping
  • Clickable prototypes tested with real users before development starts
  • Design systems with reusable components, so new screens stay consistent as the product grows
  • Accessibility designed in to the Web Content Accessibility Guidelines (WCAG) 2.2 AA from the first wireframe

Compliance built in

  • Data flows mapped early, so personal and health data is identified before it is collected
  • Accessibility decisions recorded alongside the designs for later review
  • Privacy-by-design choices documented for GDPR and HIPAA obligations
02

Minimum viable products (MVPs) for startups

Get a working product in front of customers and investors without building something you will have to throw away. The first release is small, but the foundations are the ones you scale on.

What we deliver

  • A first working release typically within 6–10 weeks of discovery
  • Architecture sized for today and ready for the next stage, with no platform team needed
  • Sign-in with passkeys and multi-factor authentication, roles and audit logging from the start
  • Analytics and feedback loops built in, so the next release is based on what users actually do

Compliance built in

  • SOC 2-ready controls in place early, so the first enterprise security review is not a rebuild
  • HIPAA-ready architecture for health products, with a Business Associate Agreement where protected health information is involved
  • Security questionnaire answers backed by real configuration, not promises
03

Web application development

Fast, accessible web applications that customers enjoy using and your team can maintain. We use mainstream technologies, so you are never locked into us to keep the product running.

What we deliver

  • React and Next.js front ends, with Node.js, .NET or Python back ends
  • PostgreSQL and managed cloud databases with sensible data models
  • Deployed to your own AWS, Azure or Google Cloud account
  • Performance, search visibility and accessibility treated as features, not afterthoughts

Compliance built in

  • Encryption in transit and at rest, with secrets kept out of code
  • Access control and audit logging on every sensitive action
  • Deployed in the regions your obligations require, including the US and EU
04

Mobile app development

iOS and Android apps that feel native and share as much as they sensibly can. We choose cross-platform or fully native based on what the product needs, not on habit.

What we deliver

  • Cross-platform apps in React Native or Flutter where one codebase fits
  • Native iOS (Swift) and Android (Kotlin) where device features or performance demand it
  • Offline support, push notifications and secure on-device storage
  • App Store and Google Play submission, review and release management

Compliance built in

  • Mobile security testing aligned with the OWASP Mobile Application Security guidance
  • Biometric and passkey sign-in with no sensitive data left on the device unencrypted
  • Privacy labels and data-use disclosures prepared from the actual data flows
05

Customer portals, partner portals and internal tools

Replace the spreadsheets, email threads and off-the-shelf tools your business has outgrown with software shaped around how you actually work.

What we deliver

  • Customer and partner portals for orders, cases, documents, billing and self-service
  • Internal tools and back-office apps that replace spreadsheet workflows
  • Connected to the systems you already run, from QuickBooks, NetSuite and HubSpot to SAP, Dynamics 365 and Salesforce
  • Single sign-on with Microsoft Entra ID, Okta or Google Workspace for staff

Compliance built in

  • Role-based access so each customer, partner and employee sees only what they should
  • Approval steps and change history on records that matter to finance or auditors
  • Access reviews made simple with clear user and permission reports
06

APIs, back ends and integrations

Back ends and APIs that other systems, partners and future products can rely on. Built to be integrated with from the first version.

What we deliver

  • Well-documented REST and GraphQL APIs with versioning from day one
  • Event-driven integrations and webhooks between your product and business systems
  • Partner and public APIs with keys, rate limits and a developer portal
  • Background jobs, file processing and reporting feeds for your data team

Compliance built in

  • API security testing aligned with the OWASP API Security Top 10
  • Every call authenticated, authorized and logged
  • Data contracts that make clear which fields carry personal or health data
07

AI features built into your product

Add AI where it helps your users, with the controls your customers' security teams will ask about. Useful features first, governance included.

What we deliver

  • AI assistants and agents inside your product, with human approval for actions that matter
  • Search and answers over your customers' own content, respecting their permissions
  • Document understanding for forms, invoices, claims and records
  • Model evaluation, tracing and cost controls through an LLM gateway

Compliance built in

  • AI governance aligned with the NIST AI Risk Management Framework, ISO/IEC 42001 and the EU AI Act
  • Customer data kept out of model training unless your customers opt in
  • Prompt, response and tool-use logs kept for review
08

Security and compliance built in

Security is part of how we build, not a review at the end. You get software, and the evidence your auditor and your customers' security teams will ask for.

What we deliver

  • Threat modeling at the start of each major feature
  • A secure development lifecycle with code review, dependency scanning and secrets detection
  • Software supply chain controls: signed builds and a software bill of materials (SBOM) for each release
  • Independent penetration testing coordinated before major launches

Compliance built in

  • Architecture built to SOC 2 and ISO 27001 controls, working alongside your auditor
  • HIPAA-ready design for protected health information, with a Business Associate Agreement where required
  • Evidence your auditor can use: control maps, change records and test results
09

Quality engineering and release automation

Ship often without breaking what customers rely on. Automated tests and pipelines make every release repeatable and traceable.

What we deliver

  • Automated unit, integration and end-to-end tests that run on every change
  • Continuous integration and delivery pipelines with preview environments
  • Feature flags and staged rollouts so new features reach users gradually
  • Monitoring, error tracking and alerting set up before launch

Compliance built in

  • Every change traceable from request to review to release
  • Separation between who writes code and who approves it for production
  • Release notes and test results kept as change evidence

How we engage

Outcomes

  1. A product you can sell

    Security and compliance questions answered from the first release, so enterprise buyers can say yes.

  2. Foundations you keep

    An architecture that grows from MVP to scale without a rewrite at every stage.

  3. Software people use

    Designs tested with real users and accessible to everyone who needs them.

  4. Releases without surprises

    Automated tests and pipelines that make shipping routine and every change traceable.

  5. Code you own

    Mainstream technologies in your own cloud account, documented so any capable team can take it on.

Typical deliverables

  • Product scope, user journeys and a prioritized release plan
  • Tested prototypes and a reusable design system
  • Working web or mobile app, APIs and infrastructure as code in your cloud account
  • Automated test suite and continuous delivery pipelines
  • Threat model, security test results and a software bill of materials for each release
  • Control map and evidence for SOC 2, ISO 27001 or HIPAA readiness
  • Architecture, runbook and handover documentation

Engagement model

  1. Assess

    Discover and scope

    A fixed-scope product or architecture assessment, typically 1–2 weeks: users, risks, compliance obligations and a release plan you can act on.

  2. Build

    Deliver in phased releases

    A first working release typically within 6–10 weeks, then phased releases that add features on the same secure foundations.

  3. Run

    Support and improve

    Monitoring, maintenance, security updates and ongoing product improvement after launch.
