Why this program matters

  • Without FastAPI mastery, developers lose an average of 50% of their time debugging poorly validated APIs, driving maintenance costs up by a factor of 3 in companies.

  • Non-asynchronous APIs cause 40% additional latency, responsible for 25% of e-commerce cart abandonment according to 2024 studies.

  • 68% of backend recruiters reject profiles without modern frameworks like FastAPI, risking forced career change or major competitive lag.

  • Every quarter without these skills exposes the company to security breaches and 20k€ in missed opportunities.

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.

The FastAPI program runs over 3 days, delivered on site.
How is FastAPI training assessed?+
Assessment relies on multiple-choice quiz to validate learning outcomes at the end of the training, continuous assessment through practical exercises and presentation of the red thread project to the trainer. Learni issues a completion certificate together with the individual assessment report at the end of the FastAPI program, which an L&D team can file as evidence.
How much does FastAPI training cost per participant?+
FastAPI training costs $3,465 per participant. For an in-company team, the flat rate starts at $6,290 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
