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 expert REST API mastery, 80% of security breaches come from poorly secured APIs, costing an average of 4M€ per incident according to Verizon DBIR.

  • Degraded performance leads to 50% slowdowns, losing 30% of customers due to churn from latencies >500ms.

  • Scalability failures block growth, with 40% of projects abandoned per Gartner.

  • Are you risking critical downtimes and revenue losses?

  • Our training avoids these pitfalls, boosts API ROI x10 through proven best practices.

Program

Module 1Advanced REST Architectures: HATEOAS modeling and microservices (Node.js, UML diagrams)

Dive into refactoring your APIs by designing HATEOAS schemas with tools like Draw.io, model interconnected microservices through practical Node.js exercises, analyze real-world Amazon cases for scaling, produce ready-to-implement deliverables diagrams, while optimizing resource discovery for smooth and performant navigation.

Module 2REST API Performance Optimization: caching, pagination, compression (Redis, Nginx)

Accelerate your APIs by implementing Redis caching in hands-on workshops, test advanced pagination and throttling on massive datasets, configure Nginx for Gzip compression, measure gains via JMeter on real e-commerce cases, generate performance reports with thresholds <200ms, transform your slow APIs into scalable machines ready for prime time.

Module 3Expert REST Security: OAuth2, JWT, rate limiting (Spring Security, Keycloak)

Strengthen your APIs against attacks by deploying OAuth2 and JWT via Keycloak in practical sessions, integrate rate limiting with Spring Security exercises, simulate OWASP Top10 breaches to counter them, audit your existing endpoints, produce secure configs as deliverables, go from vulnerable to impenetrable in no time.

Module 4REST Integration and Deployment: NoSQL databases, serverless cloud (MongoDB, AWS API Gateway)

Connect REST to MongoDB with optimized queries in real challenges, deploy serverless on AWS Lambda and API Gateway, orchestrate with Docker Compose, test CI/CD integrations with GitHub Actions, migrate a monolith to microservices, retrieve production-ready deployable deliverables to boost your cloud infrastructure.

Module 5REST Testing, Monitoring, and Documentation: automated suites, Swagger, Prometheus (Postman, Grafana)

Finalize with end-to-end Postman and Jest test suites automating 100% coverage, monitor with Prometheus/Grafana on live dashboards, generate interactive Swagger docs via exercises, review personal capstone project, obtain certification with tested API portfolio, ready to excel in production tomorrow.

Evaluation method

  • Daily technical quizzes, final complete API project, Qualiopi expert certification.

Learning method

  • 70% hands-on practice, real business cases, personalized coach feedback.

Methods, materials and delivery

The Training REST API Expert - Create Scalable and Secure 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 REST API Expert - Create Scalable and Secure 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 REST API Expert - Create Scalable and Secure 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

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.
