Integration testing Niravdas is very skilled and highly reliable. I shall work with him again when the next opportunity arises.

Java Backend- and Webdeveloper with Spring and Javascript Expertise

Kotlin Web Development (Spring BFF) Yes, performed well, and had other team members to support him (though I found that out later)
This area was relatively new to him, but he had already hand-on experience with Java, and Spring (Boot, Session, and Security).
Overall, I would recommend him, if you have a short, medium or long term project

Need to upgrade an API using spring frame to create consumer groups on Kafka Niravdas has a very good knowledge on the springframe work. He understood the requirements very quickly and was able to deliver on time. He also quickly reacts and take complete ownership of the issues. Would highly recommend him

Java Rest API Niravdas is a professional and an expert and helped me with my work deliverables.
