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.

Our social commitment
A school kit donated to a child for every training
To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.
- Backpack, notebooks and essential supplies
- Distributed through our partner charities
- Included, at no extra cost to you
The Learni story
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Why this program matters
Without advanced Haskell mastery, your code risks time-consuming memory leaks, multiplying subtle bugs by 5 according to Stack Overflow studies, degraded performance up to 10x slower compared to Scala or Rust, and loss of competitiveness: 70% of senior functional positions require monads and STM by 2025 (LinkedIn).
Imagine deadlocks blocking your production servers, faulty parsers wasting hours of debugging, or competitors snatching fintech projects worth 200k€ annually.
Miss this training, and stay stuck at intermediate level while the industry moves towards pure and scalable systems.
Invest 21 hours to multiply your market value starting tomorrow.
Program
Module 1Advanced Types and GADTs: Dive into GHC extensions for dependent types
Discover GADTs and type families, implement secure data types via practical exercises on GHCi, build a typed configuration validator, analyze real typing errors, test your implementations in pairs for an intuitive and immediate understanding of robustness gains.
Module 2Monads and Parsing: Structure complex computations with Parsec
Dive into State, Reader, and IO monads, code advanced parsers for JSON and DSL languages with Parsec, solve concrete parsing error cases, integrate monad transformers for modular stacks, produce a complete, deliverable, and optimized parser, boost your functional productivity from day one.
Module 3Performance and Concurrency: Accelerate Haskell with STM and Optimizations
Optimize lazy code with GHC profilers, implement atomic transactions via STM for concurrency, develop an asynchronous server application, benchmark before/after on real cases, finalize a scalable personal project, leave with pro tools for ultra-performant apps without deadlocks.
Evaluation method
- Daily theoretical quizzes, graded practical exercises, final project evaluated by experts.
Learning method
- 70% hands-on pedagogy, small group workshops, continuous individualized feedback.
Methods, materials and delivery
The Advanced Haskell Training - Master Monads and Performance 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 Haskell Training - Master Monads and Performance 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 Haskell Training - Master Monads and Performance 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
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.
