Learning objectives

  • Master advanced compilation to WebAssembly for professional applications
  • Develop high-performance Wasm modules integrated with JavaScript
  • Optimize WebAssembly code for native speed gains in enterprise settings
  • Implement FFI interoperability between Wasm and host languages for professional certification
  • Design secure multithreaded applications with WebAssembly
  • Deploy scalable WebAssembly solutions in production environments

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1WebAssembly Compilation: Master Emscripten and wasm-pack (advanced tools, debugging)

Dive into compiling C/C++ and Rust code to WebAssembly using Emscripten and wasm-pack, set up professional development environments, generate optimized Wasm modules, debug with tools like wasm-debugger and Binaryen, complete exercises on real enterprise benchmarks, produce your first importable Wasm module, and test its native performance for immediate speed gains.

Module 2WebAssembly Integration: Interoperability with JavaScript (Wasm JS API, bindings)

Explore the JavaScript WebAssembly API to load and instantiate modules dynamically, implement custom bindings to pass complex data between JS and Wasm, manage linear memory with Memory and Table, develop practical enterprise cases like accelerating intensive computations, test FFI interoperability on real projects, and optimize cross-language calls for professional fluency.

Module 3WebAssembly Optimization: Profiling and SIMD (Binaryen, performance tools)

Analyze Wasm module performance with advanced profilers like wasm-opt and browser devtools, apply SIMD optimizations for high-speed vector computing, reduce binary sizes via dead-code elimination and inlining, practice on enterprise scenarios like image processing or crypto, measure gains up to 10x in execution, and document reusable optimization strategies for professional skills.

Module 4Advanced WebAssembly: Multithreading and WASI (SharedArrayBuffer, system modules)

Set up WebAssembly multithreading with Atomics and SharedArrayBuffer for scalable parallel applications, integrate WASI for sandboxed system access without a browser, develop Wasm workers for intensive tasks like ML or simulations, test concurrency on real enterprise cases, manage shared thread security, and produce deployable multithreaded prototypes to boost professional projects.

Module 5Production WebAssembly: Secure Deployment and Enterprise Cases (CI/CD, security)

Deploy WebAssembly applications to production via CI/CD with GitHub Actions and Vercel, secure modules against memory attacks with guards and validation, integrate Wasm into frameworks like React or Node.js for full-stack setups, analyze real-world case studies in gaming, fintech, and AI, finalize a complete ongoing project, and prepare an enterprise adoption roadmap for immediate native performance.

Evaluation method

  • Technical MCQ on WebAssembly compilation and optimization
  • Performance benchmark evaluation on practical projects
  • Defense of the ongoing Wasm module project in real-world conditions

Learning method

  • Courses delivered by a WebAssembly expert trainer with production experience
  • Hands-on exercises on high-performance enterprise cases
  • Ongoing Wasm project from day 1 to final deployment
  • Complete pedagogical support and open-source resources

Methods, materials and delivery

The WebAssembly Training - Boosting Native Web Performance program is delivered onsite or remote (blended-learning, e-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 WebAssembly Training - Boosting Native Web Performance 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 WebAssembly Training - Boosting Native Web Performance 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

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

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.
