Don't let this gap widen

Why this program matters

  • Without expert mastery of Doctrine ORM, PHP teams waste 50% of their time on unoptimized N+1 queries, creating critical slowdowns that cost up to 25% user churn on e-commerce sites.

  • Poorly managed migrations trigger 40% of prod incidents, with average downtimes of 4h and losses of 10k€ per event according to Datadog.

  • In 2024, 68% of senior PHP job offers require advanced Doctrine, excluding non-certified profiles and blocking internal promotions.

  • Every quarter without training widens the competitive gap against rivals who scale 3x faster on the database.

Our method

How Learni guarantees the quality of your Doctrine ORM training

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

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.
Step 3

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.
Step 4

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.
