SOFTWARE & APP DEVELOPMENT
Modern software, built to support real operations
We design and build web applications, mobile apps and internal platforms that replace spreadsheets, legacy tools and manual work with reliable, maintainable systems.
Our work ranges from workflow tools and line-of-business systems through to customer-facing products and partner portals — always with clear architecture, strong engineering practices and a focus on how people actually use the software.
Example full-stack product architecture
Client applications
ResponsiveAPI & service layer
Domain-based services with clear boundaries and contracts.
Data & integration layer
Durable storage, audit and integration points.
What we design and build with clients
Most of our work sits behind the scenes: systems that teams use every day to manage operations, customers and data. We focus on making those tools clear to use, robust, and realistic for your team to run.
Web applications & portals
Browser-based tools for internal teams, partners and customers — designed to be easy to navigate, quick to respond, and dependable under load.
- • Internal workflow and case management tools
- • Customer and partner self-service portals
- • Role-based access, audit trails and reporting
Mobile apps & field tools
Native or cross-platform apps used by staff, engineers or customers on the move, often with offline use and secure sync back to core systems.
- • iOS and Android apps for field teams
- • Offline workflows with background sync
- • Push notifications and secure local storage
Core business platforms
Line-of-business platforms that become the central place to manage contracts, workflows, approvals, assets or services.
- • Contract, pricing and approval engines
- • Project and service delivery platforms
- • Multi-team, multi-region operations tooling
APIs & integration layers
Structured APIs and integration services that sit between your systems, making data flows more reliable and easier to reason about.
- • REST and event-based APIs
- • Connectors into ERP, CRM and finance systems
- • Data contracts, versioning and monitoring
Typical product flow
How we deliver software projects
We treat each project as a long-term system, not just a build. That means clear scope, straightforward architecture and delivery practices that your own team can live with after go-live.
Understand & shape
We start with your processes, users and constraints, then agree the scope and shape of the first release together.
- • Workshops with operations and stakeholders
- • User journeys and core use-cases
- • Architecture and delivery outline
Design & plan
We define screens, APIs, data structures and integration points, and agree a realistic delivery plan with you.
- • UX flows and interface outlines
- • Data model and API design
- • Incremental release plan
Build & integrate
We deliver in short, visible iterations with working software, tests and integrations landing early in the process.
- • Short sprints with demos
- • Automated tests and checks
- • Early integration and data flows
Launch & evolve
We support go-live, monitor how the system behaves in the real world and plan the next set of improvements with you.
- • Cut-over and go-live support
- • Observability and runbooks
- • Roadmap for future releases
Modern web application layout
A typical web application we build uses a component-based front-end with a clear separation between presentation, business logic and data access.
Mobile app & sync pattern
For mobile, we design around slow or unreliable networks, making sure important actions still work and data is reconciled safely when the device is back online.
How clients use software we build
Commodities & trading
A trading and approvals platform replacing email chains and spreadsheets, with full audit history and clearer risk controls.
- • Complex pricing rules captured in one place
- • Approval workflows and limits built into the system
- • Live position and exposure views for leadership
Healthcare & services
Patient-facing and staff portals that bring together bookings, records and communications from several older systems.
- • Single view of patient interactions and history
- • Self-service portals to reduce admin overhead
- • Secure data flows aligned with governance
Membership & subscription businesses
Customer platforms that manage sign-ups, renewals, entitlements and billing integrations, with clear reporting for finance and operations.
- • Clean integration into billing and CRM tools
- • Role-based access for support and operations
- • Dashboards for churn, usage and revenue
