API & backend systems
Backend engineering is a core discipline at ZyroByte. We build the APIs, data systems, and services that connect your product—and keep the business behind it running.
Architecture to operations. NDA by default.
01 / Define the contract
Versioned contracts, validated inputs, consistent errors, and documentation that helps other teams integrate.

KubernetesDepth across the backend
From an API consumed by a single app to a platform connecting teams and partners, we make the interfaces and the underlying decisions work together.
Public APIs, internal services, and partner integrations with deliberate contracts and a consistent developer experience.
Shape service boundaries around the product, workload, and team that will operate the system.
Design how data is stored, changed, and moved, including the edge cases that surface under concurrent use.
Connect payments, shipping carriers, ERPs, enterprise tools, identity providers, and AI services with visible, recoverable workflows.
Engineering beyond the happy path
Expired credentials. Duplicate events. Slow dependencies. Growing datasets. We account for the conditions a backend encounters after it goes live.
Already under load? Explore scalingAuthentication, authorization, and tenant isolation designed around who can do what.
Request schemas, payload limits, and rate controls tailored to the API and workload.
Transport encryption, scoped credentials, rotation plans, and deliberate logging practices.
Useful logs, metrics, traces, and alerts connected to documented recovery procedures.
A considered technology stack
We select tools around performance, maintainability, deployment constraints, and the people operating the system.
The runtimes behind the business logic.

Document storage
Workflows that connect services over time.
Event streaming
Message delivery
Stream processing
Repeatable environments and controlled releases.
Container packaging
Workload orchestration

Performance targets are defined against your workload and validated with representative tests. Architecture decisions include their operational cost.
From architecture to operation
A clear scope, reviewable progress, and a handover that helps your engineers own what comes next.
Understand consumers, data, integrations, load expectations, and operational constraints.
Architecture + scopeAgree on interfaces, access rules, failure behavior, and acceptance criteria.
API specification + test planImplement in increments with integration tests, security checks, and workload testing.
Reviewed, tested servicesPrepare deployment, observability, documentation, and operational handover.
Release + runbooksWe review what is already working, map dependencies, and plan changes around compatibility and migration. Your team stays involved in the decisions and the delivery.
Let’s define the right engagement
Bring your architecture, your requirements, or the problem you’re trying to solve. We’ll shape a backend engagement around the work that matters.

Scope and pricing are confirmed around your interfaces, data requirements, integrations, and delivery milestones.
Before we begin
Yes. We review the existing codebase, contracts, data model, and operational constraints first. That gives us a basis for targeted improvements, phased migrations, or a scoped replacement where needed.
We consider the consumers, integration requirements, data access patterns, and operational environment. The API style is an architecture decision made during discovery; a platform may use different interfaces for different needs.
That depends on the product and team. A modular backend can be an effective starting point. Separate services become useful when there are clear deployment, ownership, or workload boundaries that justify the operational overhead.
Yes. We connect FedEx, UPS, DHL, Canada Post, Purolator and aggregators such as EasyPost to ERPs, warehouses and storefronts, and we build complete multi-carrier shipping platforms. See our shipping integration services at zyrobyte.co/services/shipping.
Yes. We can integrate model APIs, background processing, data pipelines, and agent workflows. Scope includes the surrounding controls: access rules, job state, validation, usage visibility, and recovery from failed work.
API and backend engagements start at $10,000 CAD. Final pricing depends on the interfaces, integrations, data requirements, and delivery scope. Hosting, external services, and ongoing support are discussed separately.
Deliverables are agreed in the scope and can include the source code, API documentation, architecture decisions, automated tests, deployment configuration, and operational runbooks. We also plan knowledge transfer with the people maintaining the system.
Build on a stronger foundation.
