Technical Specification and Architecture
We begin with a technical specification that documents your data model, entity relationships, user roles and permissions, API surface, third-party integrations, and infrastructure plan. The specification is reviewed and approved before development begins. It becomes the reference document for the entire project and the handover documentation at the end.
React and Next.js Front-End
We build the front-end in React with Next.js, using TypeScript throughout. The front-end is built to the technical specification, designed for the actual users of the application, optimised for the Core Web Vitals that affect perceived performance in complex applications, and tested across browsers and devices. Component architecture is documented so your team can extend it after handover.
Node.js or Python Back-End
We build the back-end in Node.js with Express or NestJS, or in Python with FastAPI or Django, depending on your requirements and integration ecosystem. The back-end exposes a clean REST or GraphQL API, implements the business logic defined in the specification, handles file storage, queuing, and background processing where required, and is structured for the environments you will need.
Database Design
We design the database schema from your data model: PostgreSQL for relational data, MongoDB for document-oriented data, or a combination where the use case calls for it. Schema design decisions, indexing strategy, and query optimisation are made with your expected data volumes and query patterns in mind, not as defaults that will need revisiting at scale.
API Development
We build a documented, versioned API that exposes your application's capabilities to the front-end, to third-party integrations, and to any future clients, mobile applications, or partner systems. API documentation is generated from the code and kept current throughout development.
Authentication and Authorisation
We implement authentication and authorisation appropriate to your application: email and password with secure session handling, OAuth 2.0 integration for Google or Microsoft SSO, multi-factor authentication where required, and role-based access control that enforces your permission model at every layer of the stack. For applications handling personal data, authentication is implemented with UK GDPR requirements in mind: secure storage, audit logging, and user rights management built in.
Cloud Infrastructure on AWS UK/EU Region
We provision and configure your infrastructure on AWS, using UK or EU regions for applications subject to UK GDPR data residency requirements. Infrastructure is provisioned as code, with separate staging and production environments, automated deployments, monitoring, alerting, and backup configuration. We document the infrastructure so your team can manage it after handover.
Staging and Production Environments with CI/CD
We set up staging and production environments with a CI/CD pipeline from the project's start. Every change is reviewed against staging before reaching production. Deployment is automated and documented. Environment configuration, secrets management, and environment-specific settings are handled correctly from the first deployment.
Testing and Documentation
We write unit tests for business logic, integration tests for API endpoints, and end-to-end tests for critical user flows. Test coverage is reported throughout the project. Technical documentation covers the architecture, the API, the database schema, the infrastructure, and the deployment process. Handover includes a walkthrough session with your team.
