Don't let this gap widen
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.
The Haskell Training - Master High-Performance and Safe Code training is delivered in-person or remotely (blended-learning, e-learning, virtual classroom, remote in-person). At Learni, a Qualiopi-certified training organization, each program is designed to maximize skills acquisition, regardless of the training mode chosen.
The trainer alternates between demonstrative, interrogative, and active methods (through practical exercises and/or real-world scenarios). This pedagogical approach ensures concrete and directly applicable learning in the workplace.
To ensure the quality of the Haskell Training - Master High-Performance and Safe Code training, Learni provides the following teaching resources:
For in-house training at a location external to Learni, the client ensures and commits to having all necessary teaching materials (IT equipment, internet connection...) for the proper conduct of the training action in accordance with the prerequisites indicated in the communicated training program.
The assessment of skills acquired during the Haskell Training - Master High-Performance and Safe Code training is carried out through:
Learni is committed to the accessibility of its professional training programs. All our training programs are accessible to people with disabilities. Our teams are available to adapt teaching methods to your specific needs. Do not hesitate to contact us for any accommodation request.
Learni training programs are available for inter-company and intra-company settings, both in-person and remote. Registration is possible up to 48 business hours before the start of training. Our programs are eligible for OPCO, Pôle emploi, and FNE-Formation funding. Contact us to discuss your training project and funding possibilities.
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.
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.
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.
Target audience
Senior software engineers, data scientists, functional architects seeking to advance their Haskell skills.
Prerequisites
Mastery of Haskell basics, 2 years in functional programming, use of GHC, Stack or Cabal, real-world implemented projects.
