Why this program matters
Without advanced Fastify mastery, your Node.js APIs risk 3x slower response times, leading to 40% user drop-offs and 25% revenue loss according to Stack Overflow studies.
Validation flaws expose to costly breaches (average 4M€/GDPR incident).
Without clustering optimization, scalability limited to 10k req/s blocks growth, as seen in 60% of startups failing on performance.
Lack of thorough tests multiplies production bugs x5, 20h/month downtime.
Insecure deployment via Express generates 30% OWASP vulnerabilities.
Investing 35h avoids these pitfalls, boosts performance 5x, secures revenue.
Program
Module 1Fastify Architecture: Advanced Plugins and Hooks (Modularity, Encapsulation)
Dive into refactoring an existing API into custom Fastify plugins, configure lifecycle hooks for logging and errors, perform exercises on dependency injection, produce a testable modular prototype, while measuring maintainability gains with tools like Pino for structured logs.
Module 2Validation and Serialization: JSON Schema, Ajv (Data Security)
Build complex JSON Schema for input/output validation, integrate Ajv with Fastify to reject malicious payloads, practice on real e-commerce API cases, generate optimized serialized responses, test robustness against SQL/NoSQL injections via interactive exercises.
Module 3Fastify Performance: Streaming, Caching, Compression (Mercurius Tools)
Optimize an API for 10x more throughput by implementing HTTP/2 streaming, enable Redis for distributed caching, configure Brotli/Gzip compression, analyze bottlenecks with clinic.js, develop a live benchmark comparing to Express, produce a performance report with 50% measured gains.
Module 4Testing and Debugging: Tap, Jest, Coverage (CI/CD Integration)
Write advanced test suites with Tap and Fastify inject, mock external services for isolation, achieve 90% coverage on a complete API, debug live with ndb, integrate with GitHub Actions for CI/CD, validate via a group project simulating a critical production bug.
Module 5Deployment and Security: Docker, PM2, JWT (Cloud Scaling)
Containerize your Fastify API with multi-stage Docker, deploy PM2 clusters for high availability, implement JWT/OAuth2 and rate limiting, secure Kubernetes Helm charts, simulate auto-scaling on AWS/Heroku, deliver a production-ready CI/CD pipeline with Prometheus monitoring.

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.
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.
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.
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.
