I am a veteran full-stack Java/JavaScript/Go architect/developer with over 20 years of software engineering experience, a huge majority of which were ripened in large corporate and enterprise setups before I went full time freelance work around four years ago.
I am an expert with both Java EE-based technologies (JSP, servlets, EJB, JNDI, JMS, etc.) and Spring/Spring Boot and Spring Boot-based frameworks (JHipster, CUBA Platform, and Grails). Specifically, I have more than 11 years experience with Hibernate, 9 years with Spring/Spring Boot, 4 years with Groovy/Grails, and 2 years with JHipster, with Java EE experience sprinkled in between. My core technical expertise are with building highly robust and reactive Web and microservice applications, API integration and development, Web services in both RESTful and SOAP flavors, and SOA based on an ESB (Oracle Service Bus), among others. I am well-versed in both SQL and LDAP databases; my NoSQL experience is with Apache Cassandra and MongoDB.
