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.
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
Without GraalVM, traditional Java applications start 10 times slower, causing 40% losses in cloud scalability and AWS costs multiplied by 3.
Teams lose 25% of time on memory debugging on bloated JVMs, with 60% of production incidents tied to cold starts.
In 2024, 78% of leading companies adopt GraalVM for native, sidelining untrained profiles.
Every quarter without optimization widens a fatal competitive gap, risking millions in inefficiency.
Immersive discovery of GraalVM with quick installation via SDKMAN, creation of a first Java project compiled into a native executable, exploration of the polyglot JVM for integrated Python scripts, practical exercises on before/after benchmarks, analysis of CPU and memory metrics to validate immediate enterprise gains.
Deep dive into Native Image configurations to accurately reflect dependencies, use of @Register annotations for dynamic classes, profiling with GraalVM tools to identify leaks, hands-on workshops on migrating a Spring Boot app, production of quantified performance reports and a personalized optimization plan.
Mastery of the polyglot runtime to combine languages in the same native binary, development of interop APIs with Node.js and Python via Truffle, real enterprise cases such as hybrid data pipelines, multi-language unit tests, generation of deployable deliverables on Kubernetes with proven footprint reductions.
Advanced tuning techniques to minimize memory footprint under 50 MB, comparison of JIT vs AOT on real workloads, GC optimization with Epsilon and ZGC adapted to GraalVM, traffic peak simulations on microservices, collaborative exercises to refactor legacy code, live benchmarks demonstrating 10x gains in cold start.
Deployment in lightweight containers with Docker and Helm for Kubernetes, CI/CD integration via GitHub Actions and native builds, setup of monitoring with Prometheus/Grafana for GraalVM-specific metrics, review of the professional ongoing project, skill certification via MCQ and presentation, roadmap for enterprise scaling.
The Training GraalVM - Accelerating Native Java Performance 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.
For the smooth delivery of the Training GraalVM - Accelerating Native Java Performance 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.
Assessment of skills acquired during the Training GraalVM - Accelerating Native Java Performance program is performed through:
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.
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.
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.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
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.
