Don't let this gap widen
Without advanced REST API mastery, 70% of APIs remain vulnerable to breaches (source OWASP), exposing customer data to costly leaks averaging 4M€ (IBM).
Degraded performance hampers 40% of web apps, generating revenue losses up to 25%.
Developing without scaling?
Cap growth at 10k users.
Obsolete architectures lead to forced refactoring, +200h lost.
Invest 35h to avoid these pitfalls, secure your revenue and reputation today.
Dive into designing advanced REST APIs, model resources with UML, apply HATEOAS for hypermedia, version endpoints via URL or headers, complete exercises on real e-commerce cases, produce implementation-ready deliverable schemas, everything to build robust APIs that evolve without breaking clients.
Code complex endpoints with Express or Spring Boot, integrate middlewares for logging and validation, handle HTTP 4xx/5xx errors with structured responses, simulate business flows via hands-on workshops, generate functional source code, test live for immediate mastery of professional REST patterns.
Strengthen your APIs against threats, implement OAuth2 flows with Keycloak, sign JWT tokens, configure CORS and rate limiting via Redis, analyze OWASP Top 10 attacks on real cases, produce secure configurations ready for deployment, gain peace of mind with impenetrable APIs.
Boost your APIs with Redis caching, offset/limit/cursor pagination, async management via Promises or RxJS, profile bottlenecks with tools like Artillery, optimize NoSQL database queries, run live benchmarks, deliver ultra-responsive APIs scalable to 10k req/s.
Test end-to-end with Postman collections and Newman CI, containerize with Docker Compose, deploy on Kubernetes or Heroku, generate interactive Swagger UI docs, integrate CI/CD with GitHub Actions, finalize personal capstone project, leave with production-ready API portfolio.

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.
