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 mastery of A/B testing, 25% of web conversions are lost according to Google studies, directly impacting revenue with millions of euros left on the table.
Non-optimized apps accumulate technical debt, multiplying bugs by 3 and dev time by 2 according to State of DevOps reports.
Careers stagnate: developers without these skills see salaries 15% lower, and companies risk obsolescence against data-driven competitors.
Invest now in certified training to turn losses into exponential gains.
Discover advanced A/B testing basics tailored to software development, exploring testable hypotheses, statistical power calculations, and user segmentation through practical exercises on real datasets. Set up your first testing environment with JavaScript and APIs, analyze common biases for reliable results, and produce an initial report on a concrete landing page optimization case, integrating clean code from the start for easy maintenance.
Dive into code with hands-on workshops to split traffic using feature flags and design patterns like Strategy or Factory. Implement A/B variants on real React applications following clean code principles, test multi-browser compatibility, integrate analytics tracking with Google Tag Manager, simulate high loads to validate scalability, and generate deliverables like a reusable A/B module optimized for agile enterprise teams.
Design robust software architectures for large-scale A/B testing using microservices patterns and Docker/Kubernetes containers for variant deployment. Monitor real-time metrics with Prometheus and Grafana during e-commerce case exercises, manage automated rollbacks, analyze post-test conversion funnels, apply clean code to refactor legacy code, and produce a production-ready architectural blueprint in a certified professional context.
Master in-depth A/B results analysis with Bayesian methods and ML intro using Python/Scikit-learn on massive datasets. Interpret p-values, confidence intervals, and business uplift during real challenges, optimize rapid iterations with A/A tests, integrate feedback loops into software architecture, create executive reports with Tableau visualizations, and deploy a continuous optimization plan for maximum ROI in enterprise training.
The Training A/B Testing - Optimize Application Conversions 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 A/B Testing - Optimize Application Conversions 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 A/B Testing - Optimize Application Conversions 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.
