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 advanced NestJS expertise, your backend APIs risk chronic memory leaks (40% performance loss), doubled development time on microservices (team blocked 2 weeks/project), critical security vulnerabilities (85% breaches via faulty guards, GDPR fines up to 4% revenue), limited scalability (70% traffic drop at peak loads), outpaced by competitors mastering CQRS/Event Sourcing (3x ROI on deployments).
Invest 7 hours to avoid these costly pitfalls and propel your projects into smooth production.
Dive into practical workshops where you code hybrid microservices live, configure custom guards to secure critical endpoints, deploy interceptors for advanced logging and monitoring, test custom pipes on massive real datasets, optimize with Redis caching and Socket.io, build a complete deliverable: a scalable API deployed in Docker, with live trainer feedback to boost your expert skills in one intense and motivating day.
The Training NestJS Expert - Scalable and Secure Architectures 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.

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.
