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 expertise, your functional projects stagnate: concurrency bugs multiply downtimes by 40%, dev costs inflate +35% due to lack of lazy optimizations, manual parsers crash on 20% of real inputs, poorly managed concurrency exposes to memory leaks costing 10k€/incidents.
Lose markets to competitors scaling x5 faster, data scientists stuck on inefficient prototypes, teams frustrated by inferior performance.
Invest 21h to avoid these pitfalls, secure x10 ROI with stable production, undisputed tech leadership.
Program
Module 1Monads and Advanced Types: Dive into Powerful Abstractions (GHC, transformers)
Discover custom monads, applicatives, and effects through practical exercises on real data flows, implement robust error handlers, manipulate dependent types for infallible validations, test on concrete cases like config management, produce reusable modules ready to integrate, while gaining fluency and confidence to code flawlessly.
Module 2Parsing and Optimization: Handle Massive Data (Parsec, laziness criteria)
Build expressive parsers for JSON, XML or DSL languages with Parsec, refine them on large datasets, optimize via strictness and fusion to speed up x10 executions, analyze memory profiles with GHC events, resolve real bottlenecks in guided exercises, deliver a complete scalable parser, feel the power of a sharpened Haskell for your critical projects.
Module 3Concurrency and Deployment: Scale in Production (STM, Docker, CI/CD)
Model transactional concurrency with STM, integrate async for non-blocking I/O, deploy via Cabal/Nix on cloud, set up CI/CD pipelines with GitHub Actions, simulate extreme loads in real use cases, produce a full-stack app deployed, master the pitfalls for total resilience, emerge ready to boost your teams with expert Haskell.
Evaluation method
- Continuous assessment through coding exercises, advanced MCQs, final project on company case, Qualiopi certification.
Learning method
- 80% hands-on with real code, 20% targeted theory, individualized live feedback, lifetime resources.
Methods, materials and delivery
The Haskell Training - Master High-Performance and Safe Code 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 Haskell Training - Master High-Performance and Safe Code 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 Haskell Training - Master High-Performance and Safe Code 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.
