So many platforms… where do I begin?

Consider your budget, your level of expertise (are you a beginner or an experienced IT professional?), your favourite way of learning, and to help you even further, the reviews of our KWANers, tech professionals at KWAN.

I took a course at Udemy that was very important for the beginning of my career and the career of some friends, because it was very complete and helpful for beginners at C#, it’s called in Portuguese – “C# Curso Completo: Do Básico ao Avançado!”, Udemy also helped me when I started a new challenge and needed to learn Java, by offering these courses in Portuguese: “Microsserviços Java com Spring Boot e Spring Cloud”; “Design de API’s RestFul com Spring Boot, TDD e o novo JUnit5”; and “Java COMPLETO Programação Orientada a Objetos + Projetos” – Laís Ortiz, Full Stack Developer

I’m taking 3 courses at Udemy: “JavaScript: The Advanced Concepts”, “Understanding TypeScript”, and “Node JS: Advanced Concepts”. I’m enjoying them very much, especially the one about TypeScript, because the teacher explains the concepts very well and gives practical examples related to the tools I’m interested in. Furthermore, it’s easy to keep up with the classes because the course is structured in a very logical way. – Carlos Santos, Software Developer

As a sysadmin/application support specialist, is easy to focus on online courses which target technical aspects, but there is more to IT than bits and bytes.

In my line of work, communication is paramount and, if done carelessly or just wrong, can jeopardize a lot more than a bug or a glitch in the software.

LinkedIn Learning has been key to developing my soft skills, with courses like:

– “Critical Thinking for More Effective Communication”

– “Three Tips for Managing Egos and Difficult Emotions”

– “Improving Your Thinking”

– “Effective Listening”

– “Managing Anxiety in the Workplace”

These are just some of the courses which have helped me build trust, confidence and a growth mindset. – Vítor Correia, Sysadmin/Application Support Specialist
