Why this program matters

  • Without FastAPI, your APIs stay slow and buggy, causing a 40% loss in user traffic according to Stack Overflow 2023 studies, because legacy frameworks like Flask struggle against async competition.

  • Companies suffer costly security breaches, with an average cost of 4,5 millions d'euros per incident (IBM), delaying projects and hurting competitiveness.

  • Your career stalls without modern skills, 70% of backend job listings now require fast frameworks like FastAPI (LinkedIn Jobs).

  • Master it to avoid these traps and launch your projects into scalable production today.

Program

FastAPI curriculum: 4 modules over 4 days

Module 1 : FastAPI Fundamentals: Installation, First Server, and Basic Routing (FastAPI, Uvicorn, Pydantic)

Discover FastAPI by installing the environment via pip, launch your first ASGI server with Uvicorn, configure simple GET and POST routes, integrate Pydantic for automatic incoming data validation, complete practical exercises on hello world APIs, test via integrated Swagger UI, produce a first deliverable project with auto-generated documentation, while learning dependency injection concepts for a clean architecture from the beginner level.

Module 2 : FastAPI REST APIs: Advanced Endpoints and Request Management (Query Params, Path Params, Bodies)

Dive into developing complete REST APIs, handle query and path parameters to filter data, structure JSON responses with Pydantic models, manage HTTP 400 errors via custom exceptions, integrate middleware for logging and CORS, practice on concrete cases like a task management API, test with curl and Postman, generate a complete OpenAPI spec, consolidate skills with a refactoring exercise from a monolithic API to modular FastAPI.

Module 3 : FastAPI Security and Databases: JWT Auth, SQLAlchemy ORM, and Sessions

Secure your FastAPI APIs with OAuth2 and JWT via python-jose, implement a complete login/register system, connect to a PostgreSQL database via SQLAlchemy for asynchronous CRUD, migrate schemas with Alembic, manage many-to-many relationships, apply rate limiting and advanced validation, simulate attacks to test robustness, develop a protected API dashboard, obtain a deliverable with functional authentication and persistent database, strengthening professional backend security skills.

Module 4 : FastAPI Microservices and Deployment: Docker, Scaling, and CI/CD (Kubernetes Intro)

Advance to microservices by containerizing FastAPI with Docker Compose, orchestrate multiple communicating services via HTTP/gRPC, integrate Redis for distributed caching, deploy to a cloud like Heroku or Render, configure CI/CD with GitHub Actions, scale horizontally with Uvicorn workers, monitor with basic Prometheus and Grafana, complete a final e-commerce microservices project, export production-ready Docker artifacts, validate resilience with simple chaos engineering, end with FastAPI deployment skills certification.

How FastAPI skills are assessed

  • Interactive quizzes at the end of each day to validate theoretical knowledge
  • Individual and pair practical project on a complete API
  • Final evaluation through professional simulation with expert feedback

How the FastAPI course is taught

  • 100% hands-on with progressive exercises adapted to beginner level
  • Real-world use cases from French companies in production
  • Unlimited access to video replays and source code post-training
  • Personalized mentoring by certified Python/FastAPI trainers

FastAPI training: access and practical arrangements

The Training FastAPI - Developing Ultra-Performant APIs program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training FastAPI - Developing Ultra-Performant APIs program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training FastAPI - Developing Ultra-Performant APIs program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

Our method

How Learni guarantees the quality of your FastAPI training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
