Why this program matters

  • Without mastering intermediate Flask, your Python projects stagnate: routing bugs waste 40% of dev time, unsecured APIs expose you to 70% of common cyber-attacks (OWASP), manual deployment delays launches by 2 weeks, junior Flask backend salaries at 38k€ vs 52k€ for certified seniors.

  • Lose freelance contracts to Django pros, miss internal promotions, get stuck in endless debugging on forums.

  • Invest 28 hours to triple productivity, scale apps without crashes, land jobs at 60k€+ annually.

Flask training objectives

  • Master blueprints and advanced routes to structure modular apps
  • Integrate SQLAlchemy to efficiently manage relational databases
  • Implement JWT authentication and secure sessions
  • Develop RESTful APIs with Flask-RESTful and validation
  • Deploy on Heroku or Docker with Gunicorn
  • Optimize performance and test with pytest and Flask-Testing

Flask curriculum: 4 modules over 4 days

Module 1 : Advanced Flask Foundations: Blueprints, Jinja2 Templates, and WTForms Forms

Dive into creating structured applications by configuring blueprints for modularity, crafting dynamic templates with Jinja2, and validating forms via WTForms, through practical exercises on a personal blog. Deliverables: functional single-page app with advanced routing, irresistible urge to scale your Python projects.

Module 2 : Data Persistence: SQLAlchemy, Alembic Migrations, and Flask-SQLAlchemy ORM

Manipulate SQLite/PostgreSQL databases by modeling entities with SQLAlchemy, applying migrations via Alembic, and querying efficiently, on real e-commerce use cases. Exercises in insertion/search. Deliverables: database integrated into your blog app, turn your data into a competitive advantage today.

Module 3 : Security and APIs: JWT Authentication, Flask-RESTful, CSRF Middleware

Secure your apps by implementing login/register with JWT and Flask-Login, crafting RESTful endpoints via Flask-RESTful, protecting against SQL injections/CSRF, through workshops on an authenticated todo-list API. Deliverables: secure, deployable API, boost your expertise in modern web services.

Module 4 : Testing, Deployment, and Optimization: pytest, Docker, Gunicorn, Redis Caching

Write unit/integration tests with pytest and Flask-Testing, deploy on Heroku/Docker with Gunicorn, optimize via Redis caching and profiling, on a final scalable API project. Deliverables: containerized live app and performance reports, go live in production like a pro.

How Flask skills are assessed

  • Daily interactive quizzes, final deployed API project, self-assessment of skills via portfolio

How the Flask course is taught

  • 80% hands-on with real code, 20% applied theory, pair-programming exercises via video call

Flask training: access and practical arrangements

The Flask Training - Develop Scalable REST 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 Flask Training - Develop Scalable REST 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 Flask Training - Develop Scalable REST 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

How Learni guarantees the quality of your 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.
