01
Technical Specification and Architecture
We produce a full technical specification before development begins: data model, entity relationships, user roles and permissions, API design, third-party integration plan, authentication and privacy compliance approach, and infrastructure architecture on AWS Canada (Central). For health applications, the specification includes the PHIPA and PIPEDA compliance approach explicitly. The specification is approved by your team before development begins and forms the handover documentation.
02
React and Next.js Front-End
We build the front-end in React with Next.js and TypeScript, designed for the actual users of the application. For applications with bilingual French and English requirements, internationalisation is implemented at the component level from the start, not added as a translation layer after the fact. Front-end performance is verified against Core Web Vitals before launch.
03
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, based on your requirements. The back-end implements the business logic defined in the specification, exposes a clean API, and handles file storage, background processing, and notification delivery where required. For health applications, PHI access is handled at the back-end layer with explicit access controls and audit logging.
04
Database Design
We design the database schema from your data model, with indexing strategy and query optimisation matched to your expected data volumes. PostgreSQL for relational data, MongoDB for document-oriented data, or a combination where the use case requires it. For health applications, PHI fields are identified in the schema documentation and handled according to the PHIPA compliance approach defined in the specification.
05
API Development
We build a documented, versioned API for the front-end and for any third-party integrations or future mobile or partner clients. API documentation is maintained throughout the project and is part of the handover package.
06
Authentication, Authorisation, and Privacy Compliance
We implement authentication appropriate to your application: email and password with secure session handling, OAuth 2.0 for Google or Microsoft SSO, multi-factor authentication where required, and role-based access control enforced at every layer. For applications subject to PIPEDA, authentication includes audit logging and user rights management for access, correction, and deletion. For health applications subject to PHIPA, PHI access is logged, role restrictions are enforced at the data layer, and data handling is documented for privacy officer review.
07
Cloud Infrastructure on AWS Canada (Central)
We provision and configure infrastructure on AWS ca-central-1 for Canadian data residency. Infrastructure is provisioned as code, with separate staging and production environments, automated deployments, monitoring and alerting, and backup configuration meeting the recovery objectives defined in the specification. Infrastructure documentation and access are handed over as part of the project.
08
Staging and Production Environments with CI/CD
We set up staging and production environments with a CI/CD pipeline from the project's start. All changes are validated on staging before reaching production. Deployment is automated and documented. For health applications, environment separation for PHI is handled from the first deployment.
09
Testing and Documentation
We write unit tests for business logic, integration tests for API endpoints, and end-to-end tests for critical user flows. Technical documentation covers the architecture, API, database schema, infrastructure, and compliance approach. Handover includes a documentation package and walkthrough session with your team.
