Learning objectives

  • Master blueprints for scalable modular architecture
  • Implement secure JWT and OAuth2 authentication
  • Optimize performance with Redis caching and async Celery tasks
  • Deploy Flask applications in production with Docker and Gunicorn
  • Secure against OWASP Top 10 attacks
  • Integrate third-party APIs and NoSQL databases
  • Create advanced unit tests with pytest

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without this advanced Flask training, your APIs risk security breaches: 80% of web vulnerabilities come from poor authentication, as seen in OWASP 2023 reports.

  • Performance drops by 50% without Redis caching, leading to 30% user drop-offs on mobile.

  • Deploying without Docker multiplies downtime by 4, costing up to 10k€/month in business losses.

  • Missing async Celery overloads your servers, blocking scalability.

  • Result: delayed projects, unhappy clients, and competitors surpassing you with modern stacks.

  • Invest 28 hours to avoid these concrete pitfalls and boost your dev ROI x3.

Program

Module 1Modular Flask Architecture: Blueprints and Extensions (Flask-SQLAlchemy, Flask-Migrate)

Dive into restructuring Flask applications using blueprints to modularize code, install and configure essential extensions like SQLAlchemy and Migrate, perform practical exercises on database migrations, build a multi-module app with basic authentication, produce a structured deliverable ready for extension, and test live to validate scalability.

Module 2Advanced Flask Security: JWT Authentication, OAuth, and OWASP Protections

Learn to implement JWT and OAuth2 with Flask-JWT-Extended, protect against CSRF, XSS, and SQL injections via custom middleware, simulate real attacks in hands-on exercises, integrate rate limiting with Flask-Limiter, generate secure tokens for APIs, and deploy a robust authentication system on a concrete banking API case for immediate professional security.

Module 3Flask Performance: Redis Caching, Async with Celery, and Query Optimization

Boost your apps by integrating Redis for intelligent caching, configure Celery for long async tasks, optimize SQLAlchemy queries with eager loading, measure gains using profiling tools like Werkzeug, apply to a real e-commerce project with traffic spikes, produce before/after metrics showing up to 70% improvement, and master patterns for ultra-responsive apps.

Module 4Flask Deployment and Scaling: Docker, Gunicorn, CI/CD, and Cloud

Containerize your Flask app with Docker and Docker Compose, deploy on Heroku or AWS via Gunicorn and Nginx, automate CI/CD with GitHub Actions, scale horizontally on basic Kubernetes, test in a live staging environment, generate a complete production-ready pipeline, and finish with a final scalable API project ready for real production deployment.

Evaluation method

  • Daily technical quizzes
  • Final secure API project
  • Code review by the trainer
  • Self-assessment of skills

Learning method

  • Practical exercises 70% of the time
  • Real app case studies
  • Individualized hands-on projects
  • Live coded demonstrations

Methods, materials and delivery

The Advanced Flask Training - Develop Scalable and Secure APIs program is delivered onsite or remote (blended-learning, e-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.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Advanced Flask Training - Develop Scalable and Secure 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 eligible for corporate training budgets and employer-funded plans.

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.

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.
