Backend, API and web service development
We build the server side that connects mobile apps, Windows software, websites, devices and external services into one consistent product.
What the backend can handle
The first layer is intentionally jargon-free. Below are concrete examples of tasks you can bring to us.
Business logic and data
Accounts, roles, state, workflows, validation and consistent rules across client applications.
API for applications
Stable contracts for mobile, desktop and web clients with explicit errors and versioning.
Real-time events
WebSocket, push and event-driven updates where polling is not enough.
Integration layer
External APIs, CRM, devices, webhooks and legacy systems behind controlled boundaries.
You describe the task. We turn it into a technical system.
You do not need to choose a framework, protocol or architecture pattern in advance. First we define the useful outcome, existing constraints and what must not break.
Who uses it, what already exists and what outcome is needed.
What belongs in the first stage and what needs to be integrated.
Timeline and effort after analysis — not a fictional price per screen.
Architecture and operational details
If you only need the outcome, you can skip this section. If you own the technical side, this is how we approach complexity inside the system.
01Reliability by design
Authentication and authorization
OAuth/OIDC or fit-for-purpose access control with minimal exposure of sensitive data.
Idempotency and retries
Repeated requests and partial failures are handled as normal distributed-system scenarios.
Observability
Structured logs, correlation identifiers, health endpoints and useful operational signals.
Versioning
Client applications do not need emergency synchronized updates every time the server evolves.
02Production operation
Data migrations
Schema changes are planned so existing data and running clients remain consistent.
Performance
We optimize measured bottlenecks rather than guessing at scale problems too early.
Deployment
Release configuration, reverse proxy, TLS and environment separation are treated as part of the system.
Support
When something fails in production, the system should provide enough evidence to locate the problem.
Clear stages and verifiable results
A substantial software project should not become a black box for several months.
- 01
Discovery
Task, users, constraints and existing systems.
- 02
System outline
Components, data, integrations and critical risks.
- 03
Implementation
Iterations with intermediate results and validation of key scenarios.
- 04
Release
Launch, diagnostics, updates and further development.
What affects backend development cost
Complexity depends on business rules, data model, authentication, real-time behavior, external integrations and operational requirements rather than the number of API endpoints.
For non-standard software, an exact price before requirements usually means either a large safety margin or extra charges later. We define the system and risks first, then estimate the work that is actually needed.
Practical questions, answered briefly
No marketing promises — only what can be established before a project begins.
Can one backend serve mobile, web and Windows applications?+
Yes. Shared contracts and business rules are often the best way to keep multiple clients consistent.
Can you integrate with an existing API or database?+
Usually yes. We first identify the safest contract and isolate external peculiarities behind an adapter or dedicated integration layer.
Do you handle authentication?+
Yes. The exact model depends on the product, but we can work with OAuth 2.0, OIDC, token-based access and role-based authorization.
