Haskell curriculum: 4 modules over 4 days

Module 1 : Advanced Haskell Types: GADTs and Dependent Types (GHC extensions, typing exercises)

Dive into dependent types and GADTs with GHCi to model complex structures, practice defining advanced type classes on real business cases, implement type families to validate invariants at compile time, analyze common typing errors through interactive exercises, produce a securely typed module as a deliverable with personalized feedback from the trainer.

Module 2 : Functional Abstractions in Haskell: Monad Transformers and Effects (mtl, transformers)

Build custom effect stacks with monad transformers to manage state and exceptions, apply patterns like ReaderT and StateT on simulations of professional applications, experiment with mtl libraries to compose reusable abstractions, solve complex challenges in a virtual team, generate a modular, testable component deployable in a certified context.

Module 3 : Haskell Performance: Profiling and Parallelism (GHC runtime, async, parmonad)

Profile Haskell applications with GHC events and +RTS to identify bottlenecks, optimize memory and garbage collector via advanced flags, implement parallelism with Control.Parallel and async on large datasets, test load scenarios remotely, produce a before/after benchmark with measurable gains, apply techniques for enterprise production scalability.

Module 4 : Real-World Haskell Applications: APIs and Deployment (Servant, Yesod, Docker, CI/CD)

Develop a complete REST API with Servant for end-to-end typing, integrate Yesod for secure web apps, containerize with Stack and Docker for smooth deployment, set up CI/CD via GitHub Actions on the red thread project, simulate production loads with automated tests, finalize a deployed deliverable accessible with professional certified documentation.

Haskell training: access and practical arrangements

The Training Haskell - Mastering Scalable Functional Development 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 Training Haskell - Mastering Scalable Functional Development 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 Training Haskell - Mastering Scalable Functional Development 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.

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.

Our method

How Learni guarantees the quality of your Haskell 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.

FAQ

Haskell: frequently asked questions

Which tools are used in Haskell training?+
Hands-on work runs on GHC extensions, typing exercises, mtl, transformers, GHC runtime and async. Those tools come from the Haskell program itself, delivered on site over 4 days, so participants practise on the stack they will use at work.
What can participants do after Haskell training?+
They can master advanced Haskell types for robust professional applications, develop powerful functional abstractions in a business context and implement concurrency and parallelization with certified Haskell. Those are the stated objectives of the Haskell program at Advanced level, checked by the end-of-session assessment.
What does the Haskell program cover, day by day?+
Day 1: Advanced Haskell Types: GADTs and Dependent Types (GHC extensions, typing exercises). Day 2: Functional Abstractions in Haskell: Monad Transformers and Effects (mtl, transformers). Day 3: Haskell Performance: Profiling and Parallelism (GHC runtime, async, parmonad). Day 4: Real-World Haskell Applications: APIs and Deployment (Servant, Yesod, Docker, CI/CD). The Haskell program runs over 4 days, delivered on site.
How is Haskell training assessed?+
Assessment relies on multiple-choice quiz to validate learning outcomes at the end of the training, continuous assessment through practical Haskell exercises and defense of the red thread project in front of the expert trainer. Learni issues a completion certificate together with the individual assessment report at the end of the Haskell program, which an L&D team can file as evidence.
How much does Haskell training cost per participant?+
Haskell training costs $4,620 per participant. For an in-company team, the flat rate starts at $7,865 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
How long does Haskell training take?+
4 days, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.
Who pays for Haskell training?+
Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.
What do participants need to know before Haskell training?+
Mastery of Haskell syntax, pure functions, polymorphic types, and basic monads.
Is a certificate issued after Haskell training?+
Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
