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.
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.
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.
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.
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:
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:
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.
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.
Rigorous trainer selection
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
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.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
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.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.

A school kit donated to a child for every training booked
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.
30 minutes with a learning advisor. No commitment. No sales pitch dressed up as a demo.
