Learning objectives

  • Master dependent types and GADTs for infallible code
  • Optimize performance via lazy evaluation and fusions
  • Design advanced custom monads and transformers
  • Implement concurrency with STM and async
  • Develop parser combinators and reactive systems
  • Manage complex projects with Stack, Cabal, and Hackage
  • Apply scalable Haskell in production

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 expertise, memory leaks eat 25-40% performance, concurrency bugs cause 15% downtime (cost 50k€/fintech incidents).

  • Development 2x slower without dependent types, loss of blockchain contracts (100B€ market).

  • Junior teams multiply bugs 3x, 20% turnover.

  • Obsolescence risk: 70% Haskell devs stagnate without upskilling.

  • Our training avoids these pitfalls, boosts productivity 50%, secures ROI on critical projects from week 1.

Program

Module 1Advanced Types: GADTs, DataKinds, singletons in Haskell

Dive into dependent types, manipulate GADTs to validate dynamic structures, build a typed configuration validator through practical exercises, analyze libraries like aeson, leave with ready-to-use templates for your secure APIs, boost code reliability starting tomorrow.

Module 2Optimizations: laziness, strictness, Haskell fusions

Master lazy evaluation for massive performance gains, apply strict BangPatterns annotations on benchmark cases, fuse lists via rewrite rules, test scaling on million-entry datasets, integrate GHC profiling to detect bottlenecks, transform slow apps into high-performance rockets.

Module 3Advanced Monads: transformers, MTL, custom in Haskell

Create stacked monads for logging + state + IO, implement ReaderT and StateT on real projects, chain effects via advanced do-notation, debug complex compositions, deploy reusable patterns in personal libraries, make your functional apps ultra-modular and expressive.

Module 4Concurrency: STM, async, Haskell parallelism

Develop transactional systems with Software Transactional Memory, parallelize via parMonad and evaluate, manage async channels for data pipelines, simulate high-throughput workloads, measure speedup up to 8x cores, secure fintech apps against deadly race conditions.

Module 5Pro Projects: Stack, Cabal, Haskell deployment

Build end-to-end project with Stack for reliable dependencies, package via Cabal hpack, integrate Hackage + Docker, deploy on AWS Lambda serverless, pair-programming code review, deliver concrete deployable portfolio, launch immediate production Haskell career.

Methods, materials and delivery

The Training Haskell Expert - Master Advanced Types and Concurrency 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 Expert - Master Advanced Types and Concurrency 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 Expert - Master Advanced Types and Concurrency 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.

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.
