Learning objectives

  • Master Dapper for ultra-fast SQL queries in certified professional training
  • Develop expert skills in object-relational mapping for agile companies
  • Design scalable backend architectures with Dapper in a startup context
  • Optimize database performance for freelancers and business creation
  • Implement advanced Dapper patterns in real certified projects
  • Deploy secure and maintainable Dapper solutions for tech entrepreneurs
  • Evaluate Dapper's impact on professional competitiveness in business

The Learni story

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

Why this program matters

  • 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.

Program

Module 1Advanced Dapper: Complex Mapping and Multi-Results (C#, SQL Server)

Dive into multi-result queries with Dapper, explore anonymous projections and custom handlers for complex joins, complete practical exercises on real startup datasets, configure extensions for JSON and spatial data, produce a scalable backend prototype with before/after benchmarks, integrate logging and error handling for professional robustness in 7 intensive hours.

Module 2Dapper Performance: Advanced Batching and Caching (PostgreSQL, Redis)

Optimize performance through massive batching and distributed transactions in Dapper, implement hybrid caching with Redis to accelerate freelance APIs, analyze slow SQL profiles on real growth company cases, develop dynamic stored procedures, test under load with tools like BenchmarkDotNet, deliver an optimized module reducing response times by 70% for critical applications.

Module 3Dapper Security: Injections and Row-Level Security (EF Comparison)

Secure Dapper access against advanced SQL injections and implement RLS on PostgreSQL, compare with Entity Framework for expert migrations, code dynamic guards and RBAC policies, simulate OWASP attacks on startup scenarios, generate automated audits, deploy a secure service with JWT integration, obtain a resolved vulnerabilities report in practical certified training.

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.

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.
