Why this program matters

  • Without advanced Flask mastery, 70% of apps suffer OWASP security flaws, causing costly breaches averaging 200k€.

  • Response times >2s drive away 40% of users, multiplying churn by 3.

  • Monolith maintenance explodes budgets 4x while competitors scale 10x faster.

  • Production downtimes at 5k€/h hit revenue, and 85% of backend job postings require these skills.

  • Stagnate, lose promotions to trained juniors, and miss innovative projects in a Python market booming +30%/year.

Advanced Flask training objectives

  • Modularize applications with blueprints and Flask extensions
  • Implement secure JWT authentication and RBAC authorization
  • Optimize performance via caching, async processing, and load balancing
  • Integrate SQLAlchemy for advanced ORM and migrations
  • Build RESTful APIs with tests and validation
  • Deploy to the cloud with Docker, CI/CD, and monitoring

Program

Advanced Flask curriculum: 4 modules over 4 days

Module 1 : Modular Architecture: blueprints, Flask extensions (modularity, SQLAlchemy, tests)

Structure your apps with reusable blueprints, integrate Flask-SQLAlchemy and Flask-WTF for secure forms, refactor a monolithic app through practical exercises on a real e-commerce case, generate tested blueprints with pytest, adopt design patterns for infinite scalability, while boosting your productivity from day one.

Module 2 : Security and Authentication: JWT, OAuth, CSRF protections (tokens, middleware, hashing)

Deploy JWT with Flask-JWT-Extended for stateless sessions, configure OAuth2 via Authlib, protect against SQL injections and XSS with custom middleware, simulate real attacks in hack-proof exercises, produce a complete auth system with RBAC roles, gain confidence for critical production apps.

Module 3 : Advanced Databases: SQLAlchemy ORM, async queries (models, relations, caching)

Master complex relationships and optimized queries with SQLAlchemy, implement Redis caching to speed up responses 10x, migrate schemas via Alembic on PostgreSQL, analyze performance logs in a banking business case, create advanced CRUD with pagination, transform your data into an ultra-fast competitive advantage.

Module 4 : Deployment and Optimization: Docker, CI/CD, monitoring (cloud, Prometheus, scaling)

Containerize with Docker and Kubernetes, automate GitHub Actions pipelines for zero-downtime deployments, monitor with Prometheus and Grafana on AWS/Heroku, scale horizontally via Gunicorn, test a full-stack deployment live, leave with a production-ready app and DevOps skills to boost your career.

Advanced Flask training: access and practical arrangements

The Advanced Flask Training - Develop 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 Advanced Flask Training - Develop 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.

Our method

How Learni guarantees the quality of your Advanced Flask training

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.
