Don't let this gap widen
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.
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.
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.
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.
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.
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.

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.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
