Services

Everything it takes to ship serious software.

We cover the full product lifecycle — strategy, design, engineering, and operations. Here is what each discipline involves, the problems it solves, and what you can expect from us.

01 — Custom Software Development

Software shaped around how your business actually works.

Off-the-shelf tools force you to adapt your operations to someone else's assumptions. We build software that fits your processes, encodes your domain knowledge, and grows with the business — instead of becoming the next thing you work around.

Problems it solves

  • Critical workflows held together by spreadsheets, email, and manual hand-offs
  • Generic platforms that no longer fit how your teams operate
  • Legacy systems that are expensive to change and risky to touch
  • Data scattered across tools with no single source of truth

What we deliver

  • Domain modelling and solution architecture
  • Production-ready application with documented codebase
  • Integrations with your existing systems and data
  • Automated tests, CI/CD pipelines, and deployment setup
  • Handover documentation and ongoing support options
  • TypeScript
  • Node.js
  • NestJS
  • React
  • PostgreSQL
  • Docker

02 — Web Application Development

Web applications built for real users and real load.

From customer-facing platforms to internal tools, we build web applications that are fast, accessible, and maintainable. We pay as much attention to the architecture underneath as to the interface people interact with.

Problems it solves

  • Slow, fragile front-ends that frustrate users and hurt conversion
  • Products that worked as a prototype but struggle under real usage
  • Codebases that have become difficult to extend without regressions
  • Poor search visibility and inconsistent performance across devices

What we deliver

  • Responsive, accessible web application
  • Component architecture and design-system implementation
  • Server rendering, caching, and performance optimisation
  • Authentication, roles, and permissions
  • Analytics, monitoring, and error tracking setup
  • React
  • Next.js
  • TypeScript
  • Node.js
  • PostgreSQL
  • AWS

03 — Mobile Application Development

Native-quality mobile experiences for iOS and Android.

We build cross-platform mobile apps with React Native, sharing logic across iOS and Android without compromising on the details users notice — smooth interactions, offline resilience, and platform-appropriate behaviour.

Problems it solves

  • Needing presence on both iOS and Android without doubling cost
  • Mobile apps that feel like wrapped websites rather than products
  • Unreliable behaviour on poor connections or older devices
  • Complex release processes and app store friction

What we deliver

  • Cross-platform iOS and Android application
  • Offline support, push notifications, and device integrations
  • Shared API layer with your web platform
  • App store preparation and release pipeline
  • Crash reporting and release monitoring
  • React Native
  • TypeScript
  • Node.js
  • MongoDB
  • PostgreSQL

04 — SaaS Product Development

SaaS platforms engineered to launch — and to scale after.

Building a SaaS product means getting more than features right. Multi-tenancy, billing, permissions, onboarding, and observability all need to be designed in from the start. We help you get to market with foundations that won't need rebuilding at the first sign of growth.

Problems it solves

  • Turning a validated idea into a product customers will pay for
  • MVPs built for speed that now block growth
  • Tenant isolation, billing, and access control added as afterthoughts
  • Unclear technical roadmap from first release to scale

What we deliver

  • Product architecture and technical roadmap
  • Multi-tenant application with roles and permissions
  • Subscription billing and account management
  • Admin tooling, onboarding, and usage analytics
  • Scalable infrastructure with automated deployments
  • Next.js
  • NestJS
  • TypeScript
  • PostgreSQL
  • AWS
  • Docker

05 — UI/UX Design

Interfaces that are clear, considered, and built to be built.

Good design reduces friction for users and ambiguity for engineers. We design user flows, interfaces, and design systems with implementation in mind — so what gets approved is what gets shipped.

Problems it solves

  • Users dropping off at key steps without a clear reason
  • Inconsistent interfaces that grew screen by screen
  • Designs that look right but are impractical to implement
  • No shared language between product, design, and engineering

What we deliver

  • User research synthesis and journey mapping
  • Information architecture and user flows
  • Wireframes and interactive prototypes
  • High-fidelity UI design
  • Design system with reusable components and tokens
  • Figma
  • Design Systems
  • Prototyping
  • Accessibility (WCAG)

06 — Backend & API Engineering

The reliable systems behind the product.

Every product is only as dependable as what runs behind it. We design and build APIs, services, and integrations that are secure, observable, and well documented — ready for the traffic, partners, and features still to come.

Problems it solves

  • APIs that are slow, inconsistent, or poorly documented
  • Integrations with third-party systems that break silently
  • Monolithic backends that are hard to scale or deploy safely
  • Limited visibility into errors, performance, and usage

What we deliver

  • API design (REST or GraphQL) with versioning strategy
  • Service architecture and data modelling
  • Third-party and internal system integrations
  • Authentication, authorisation, and security hardening
  • Logging, metrics, alerting, and API documentation
  • Node.js
  • Express
  • NestJS
  • PostgreSQL
  • MongoDB
  • Docker
  • AWS

How we engage

Flexible ways to work together.

Every engagement includes transparent progress reporting, documented code, and a clean handover whenever you need it.
  1. 01

    Fixed-scope project

    Best for well-defined products and tenders

    An agreed scope, timeline, and price. We start with discovery to define requirements precisely, then deliver against clear milestones and acceptance criteria.

  2. 02

    Dedicated engineering

    Best for evolving products

    Engineering capacity working continuously on your roadmap, billed on time and materials. Priorities can change as you learn — without renegotiating a contract.

  3. 03

    Partner & subcontractor

    Best for agencies, integrators, and consortia

    We join larger programmes as the engineering partner — delivering defined work packages for prime contractors, agencies, and tender consortia under their governance.
