What can participants do after Kotlin training?+
They can master advanced Kotlin features for professional multiplatform applications, develop high-performance concurrent systems with Kotlin coroutines and implement Kotlin Multiplatform to share code between Android, iOS, and web. Those are the stated objectives of the Kotlin program at Expert level, checked by the end-of-session assessment.
What does the Kotlin program cover, day by day?+
Day 1: Advanced Kotlin Features: extensions, DSL and null safety (IntelliJ, Gradle). Day 2: Kotlin Coroutines: Expert Asynchronous Programming (Dispatchers, Flow, Channels). Day 3: Kotlin Multiplatform: Code Sharing Android/iOS/web (KMP, Compose Multiplatform). Day 4: Kotlin Best Practices: Testing, Security, and Deployment (Kotest, Ktor, CI/CD). The Kotlin program runs over 4 days, delivered on site.
How is Kotlin training assessed?+
Assessment relies on expert MCQ to validate learning outcomes at the end of the training, continuous assessment through advanced practical Kotlin exercises and presentation of the multiplatform red thread project. Learni issues a completion certificate together with the individual assessment report at the end of the Kotlin program, which an L&D team can file as evidence.
How much does Kotlin training cost per participant?+
Kotlin training costs $4,620 per participant. For an in-company team, the flat rate starts at $7,865 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
How long does Kotlin training take?+
4 days, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.
Who pays for Kotlin training?+
Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.
What do participants need to know before Kotlin training?+
Advanced proficiency in Java or intermediate Kotlin, experience in Android or JVM server development.
Is a certificate issued after Kotlin training?+
Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
Does Learni provide the equipment for Kotlin training?+
No. A computer and a stable internet connection are required for each participant. Learni provides the learning platform, the trainer and all course materials.
