Working in the Software Engineering sector since 2010, with experience in a variety of areas such as ERP, TELCO, Aerospace, E-commerce, Traffic Monitoring & Urban Mobility, Public Transport, User Analytics, Payment Processes, and Credit Cards Manufacturing being implemented using different platforms such as UNIX/BASH, JVM (Java/Kotlin/Groovy/Scala), Elixir, and Javascript/Node. My technical expertise has been shifting in the last years over Reactive Systems and Reactive Architecture, all based on my experience not only designing such architectures at the integration level but also with a deep understanding of internal processes such as non-blocking IO implementations, threading models, and asynchronous integration in order to design the system to be Reactive. Apart from my commercial experience I also worked as a Professor at a university in Brazil, where I could teach about System Integration and had the pleasure to publish my first scientific article, about Scalability in applications with a high number of write operations in relational databases. In the last two years I also started to review books from manning (https://www.manning.com/) during my free time, where I had the opportunity to work on the revision of the following books: - Microservices Security in Action (https://www.manning.com/books/microservices-security-in-action) - Vert.x in Action (https://www.manning.com/books/vertx-in-action) - Istio in Action (https://www.manning.com/books/istio-in-action) - Models and Algorithms for Unsupervised Learning (https://www.manning.com/books/models-and-algorithms-for-unsupervised-learning) - How to read Java (https://www.manning.com/books/how-to-read-java) If you are interested and seeing about my career progress you can look at my GitHub, where I have some Open projects from last years, built in order to learn or improve my skills in many different languages. https://github.com/leosilvadev/ I also have a Youtube channel where I created some courses about Javascript, Angular 1.x, and Spring (OLD ones) in Portuguese and also created one course about RxJava2 in English (not completed) https://www.youtube.com/channel/UC4I5zgAzQMpAC44C4jH-JGA
