The Learni story
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
Why this program matters
Without this expert C training, risk memory leaks draining 30% of system performance, like 70% of senior devs according to Stack Overflow.
Imagine multithread crashes causing 2h downtime/day, costing 5000€/incident in production.
Unpatched vulnerabilities expose to Heartbleed-like breaches, with GDPR fines up to 4% of revenue.
Lose IoT/embedded contracts to optimized competitors.
80% of teams without expert upskilling see critical bugs x3, hindering innovation.
Invest now to avoid these costly pitfalls and dominate critical systems.
Program
Module 1Memory Management and C Optimization: Advanced Pointers, Custom Allocators (GCC, Valgrind)
Dive into the deep mechanisms of memory with GCC and Valgrind, implement custom allocators to reduce latencies, track leaks through exercises on real embedded cases, produce a quantified optimization report, transform your skills into immediate assets for ultra-high-performance critical systems.
Module 2Multithreading and Concurrency in C: pthread, Atomic Locks (Benchmarks, Deadlocks)
Build robust multithreaded applications with pthread, simulate deadlocks to resolve them live, measure gains via custom benchmarks, integrate atomic primitives for maximum scalability, leave with a tested thread-safe prototype ready to boost your high-performance projects.
Module 3Advanced Debugging and C Security: GDB, Fuzzing, Protections (Final Deliverable Project)
Master GDB for intensive debugging sessions on complex code, apply AFL fuzzing to hunt vulnerabilities, reinforce against buffer overflows and injections, finalize a complete system project with source deliverable and security report, gain expertise for zero-defect production deployments.
Evaluation method
- Continuous assessment through practical exercises, technical quizzes, and graded final project.
Learning method
- 100% hands-on active pedagogy, small group workshops, individualized feedback.

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.
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.
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.
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.
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.
