Our social commitment

A school kit donated to a child for every training

To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.

  • Backpack, notebooks and essential supplies
  • Distributed through our partner charities
  • Included, at no extra cost to you

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Module 1ServiceStack Fundamentals & Setup

Introduction to ServiceStack and its "API-First" philosophy. Presentation of the ecosystem, differences with Web API/.NET Core, installation and configuration of a first ServiceStack application, project structuring, routes and request/response management. Creation of first REST services, principles of JSON/XML/CSV/ProtoBuf serialization. Exercises: Creation of a simple API, handling output formats, error management.

Module 2Advanced Services, Security, and Validation

Deep dive into DTO management (Data Transfer Objects), experimentation with filters, hooks, and Interceptors. Securing APIs via authentication (JWT, API Key, OAuth), roles and permissions, configuration of identification providers. Implementation of data validation with ServiceStack.Validation, global error handling, and customized response formatting. Exercises: Adding security and validation to endpoints.

Module 3Optimization, Documentation, Tests, and Deployment

ServiceStack API optimization techniques (caching, compression, throttling management, profiling). Setting up interactive documentation (Open API/Swagger). Using ServiceStack automated testing tools (integration testing, unit testing on services and filters). Deployment strategies on IIS, Docker, Azure, and AWS. Best practices for monitoring and maintenance. Practical workshop: development of a complete mini-API, secured and documented, automated tests, and production preparation.

Evaluation method

  • Formative assessments through exercises and practical cases at the end of each day
  • Final validation MCQ
  • Red thread project (development and securing of a real API)

Learning method

  • Lectures illustrated with concrete examples
  • Individual practical work and mini-projects
  • Personalized corrections and continuous feedback
  • Complete course materials, reusable source code, supplementary resources (official links, community tools)

Our method

Training quality, guaranteed at every step

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.
