Overview

What Are Backend & API Development Services?

Backend development is the server-side engineering that handles business logic, data storage, authentication, and system integration - the part of a software system users don't see but that everything depends on. A well-built backend is secure, performant, documented, and maintainable. REST API development specifically means building structured HTTP interfaces that allow different systems - web apps, mobile apps, third-party services - to communicate reliably and consistently.

StrataGrid builds backend infrastructure for enterprise clients and government organizations across Canada, including Toronto-based headquarters, federal departments, provincial agencies, and regulated industries that need APIs built to public-sector standards.

Why StrataGrid

Why Choose StrataGrid for Backend & API Development

Scalable Architecture

We design backend systems to handle growth - from hundreds to millions of requests - without requiring a full rewrite as your organization scales.

Secure by Design

Every API we build includes proper authentication, rate limiting, input validation, CORS configuration, and logging. Security is not an afterthought.

Full API Documentation

We deliver complete OpenAPI/Swagger documentation with every API - so your frontend teams, integration partners, and future developers always know exactly how to use it.

High Performance

Query optimization, connection pooling, caching layers (Redis), and efficient data serialization ensure your API responds fast under real-world load.

Reliable Integrations

We build integration middleware that handles retry logic, error states, data transformation, and monitoring - so your connected systems stay synchronized reliably.

Standards-Aligned

Our APIs align with Government of Canada API standards: RESTful design principles, versioning, consistent error responses, and OpenAPI documentation.

Our Process

Backend & API Development Delivery Process

We follow a clear, structured process so every decision, milestone, and handoff is documented.

01

Discovery

We take time to understand your problem, users, workflows, and goals before writing a single line of code.

02

Solution Design

We map out the structure, features, and roadmap - giving you a clear picture of what will be built and why.

03

Software Development

We build the application, backend, APIs, automation tools, and supporting systems using modern, maintainable practices.

04

Testing & QA

We test thoroughly, fix issues, and confirm the solution is reliable before it reaches your users.

05

Deployment & Support

We launch the solution and provide ongoing support and improvements as your needs evolve.

Who We Work With

Backend & API Development for Real Operating Environments

These are the teams, workflows, and operating models where this work creates the most value.

Government Data APIs

APIs that expose government data to authorized consumers - citizen portals, third-party integrators, inter-departmental systems - with proper access controls and audit logging.

System Integration

Integration middleware that connects legacy systems, ERP platforms, CRMs, and cloud services - allowing data to flow reliably between systems with different data models.

Mobile App Backends

Backend APIs that power mobile applications - handling user authentication, data sync, push notifications, and offline reconciliation.

Microservices & Event-Driven Systems

Decomposed backend architectures where independent services communicate through well-defined APIs and message queues - enabling independent deployment and scaling.

Data Pipelines

ETL pipelines that extract data from source systems, transform it according to business rules, and load it into reporting databases, data warehouses, or downstream applications.

Authentication & Identity Services

Custom identity platforms or integrations with existing IdPs - supporting SSO, multi-factor authentication, role-based access, and identity federation.

FAQ

Questions About Working Together

What programming languages do you use for backend development?

We primarily use Node.js (TypeScript/JavaScript), Python (FastAPI, Django), and C# (.NET). The choice depends on your existing environment, team preferences, and performance requirements. All three are modern, widely-supported, and maintainable long-term.

Do you follow RESTful API design standards?

Yes. We follow REST best practices: resource-based URLs, proper HTTP method semantics, consistent error response formats, versioning strategy, and full OpenAPI documentation. For Canadian government APIs, we also align with the Government of Canada API standards.

How do you handle API versioning?

We implement versioning from the start using URL-path versioning (e.g., /api/v1/, /api/v2/) and maintain backward compatibility across versions. Breaking changes are introduced in new versions with a documented deprecation timeline.

Can you integrate our backend with Microsoft 365 or Azure services?

Yes. We frequently integrate backend systems with Microsoft Graph API, SharePoint, Teams, Azure Service Bus, Azure Blob Storage, and Azure Active Directory - particularly for government clients already using Microsoft's cloud infrastructure.

What's the difference between REST and GraphQL? Which should we use?

REST APIs expose fixed endpoints that return predefined data structures. GraphQL lets clients specify exactly what data they need in a single request. REST is simpler to cache, document, and secure - making it the better choice for most government and enterprise use cases. GraphQL is better when clients have highly variable data requirements and you want to minimize over-fetching. We can help you choose based on your specific needs.
