How the years went by:

Full circle on Java

Returned to office. Now working on legacy codes with EJB, JDBC, SOAP/REST APIs and to old and trusty Eclipse.

Freelance again (Pandemic WFH trend)

Got to work on many JS UI getting popular; ReactJS/NextJs, VueJs/Nuxt, NestJs but still consistent with Laravel projects.

Back to corporate with opportunities to use

Spring, SpringBoot, NodeJs/ExpressJs, SOAP/REST APIs, Zend, Laravel, VueJs, AngularJs, PolymerJs. Dabbled a bit on mobile with Flutter/Dart

Started Freelancing

Introduction to WordPress, Shopify and CodeIgniter as these are the most sought after platforms this during this time.

First role as Junior Developer

Started using two stacks. PHP with MySQL then Java (JSP, JDBC, Servlets), PostgreSQL. Eventually adopted Spring and Hibernate.
