Development on FastAPI
Super speed
FastAPI is one of the fastest frameworks, often comparable in speed to Node.js and Go
async support
Supports asynchronous programming based on Starlette - high performance

Why choose FastAPI?

Speed, reliability and modern approach
FastAPI combines speed, auto-generation of documentation and strict validation through type hints and Pydantic
Very fast startup
Start an API or MVP in a matter of hours thanks to minimal setup
Async-first
ASGI-based asynchrony (Starlette) - excellent scalability
Auto documentation
Swagger UI and ReDoc are generated automatically from schematics
Strict Validation
Pydantic + type hints reduce errors and ensure reliability
200–300%Speed up development
40%Fewer errors
+100OpenAPI schemes immediately
99.9%Reliability and scalability

What tasks do we use it for? FastAPI

Below are scenarios where this technology really helps a business: it speeds up launch, simplifies support, or provides the right architecture for growth.

APIs and integrations

We connect CRM, CMS, payment gateways, ERP and internal services through stable APIs.

Process automation

We write background tasks, data processors, imports, exports and pipelines.

AI and data-driven products

We are building a service layer for ML models, classification, generation and search.

When technology is suitable and when it is not

Suitable if

  • FastAPI is suitable for services that require APIs, integrations, automation and controlled growth of functionality.
  • Useful for MVP, internal systems and products with non-standard business logic.
  • Suitable when you need quick iteration of hypotheses without unnecessary boilerplate code.

It's better to consider another way if

  • Not the best choice if the task comes down to only a standard storefront without backend logic.
  • Requires a well-thought-out infrastructure if a very high load and complex distributed architecture are immediately expected.

What is included in the work

  • Service architecture, data model and API contracts.
  • Authorization, roles, queues, background tasks and integrations.
  • Test coverage, logging, monitoring and deployment.
  • Transfer of documentation and post-launch support.

Stages of work

  1. 1Architecture and designWe plan the structure, select async patterns, validation and documentation systems.
  2. 2Prototype and documentationWe create a basic API with auto-generation of Swagger UI/ReDoc.
  3. 3Development and integrationWe implement endpoints, connect databases, caches, queues, external services.
  4. 4Testing and optimizationWe carry out load testing, unit and integration tests, CI/CD.
  5. 5Deployment and maintenanceSetting up the Uvicorn server, monitoring (Prometheus/OpenTelemetry), secure production.
