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
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.
Dive into expert Rollup configuration via rollup.config.js, set up the dedicated Node.js environment, create your first multi-format build for professional libraries, test named exports and basic tree-shaking on real projects, analyze bundle sizes with analyzer tools, produce production-ready optimized deliverables, and complete practical exercises on enterprise cases for immediate performance gains.
Integrate essential plugins like @rollup/plugin-babel for transpilation, @rollup/plugin-terser for aggressive minification, configure custom transformation chains, apply to legacy and modern code, measure impacts with real benchmarks, develop a simple custom plugin for specific enterprise needs, test robustness with watch mode and hot-reload, generate detailed bundle reports, and build certifiable bundling skills by the end of the day.
Master advanced tree-shaking to eliminate 40% of typical dead code, implement code splitting with dynamic imports for scalable apps, configure parallel output chunks, analyze dependency graphs via rollup-plugin-visualizer, optimize for production edge cases like SSR, practice on the enterprise red thread project, measure ROI with Lighthouse audits, produce 30% lighter bundles, and apply certified techniques to boost SEO and user UX.
Integrate Rollup into CI/CD pipelines with GitHub Actions or Jenkins, automate multi-environment builds for dev/staging/prod, configure advanced caching to accelerate compile times by 50%, monitor bundles via Sentry or custom dashboards, deploy to Vercel/Netlify with previews, test end-to-end real-world performance, finalize the red thread project with trainer code review, receive support resources for lasting enterprise skills, and transform bundling workflows into an immediate competitive advantage.

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.
