About

As a certified Spark & Hadoop Developer (CCA175) and Confluent Certified Kafka Developer (CCDAK), I bring a decade of experience in implementing enterprise application solutions using a diverse range of technologies including Core Java, J2EE, RESTful services, Hibernate, Spring Framework, Servicemix ESB, Apache Camel, Spark, Sqoop, Hive, HDFS, Kafka, Cassandra, and various testing frameworks. My current role as a Senior Software Engineer at Luxoft involves working on the Analytics platform and support team, where I manage data pipelines from various sources to the Hadoop platform, develop Spark jobs for ETL processes, and create oozie workflows for Tableau reporting. Previously, at CIGNEX, I specialized in Big Data solutions as a Senior Software Engineer. My career also includes significant contributions at Brodos AG and Silver Touch Technologies Ltd, where I managed backend server development, created and integrated multiple services, and adhered to SCRUM Agile methodologies for project management. With a Bachelor's degree in Computer Science from Hemchandracharya North Gujarat University and multiple certifications, my technical expertise spans big data technologies, real-time big data CEP, and extensive Java/J2EE development. Proficient in English, I am equipped to tackle complex technical challenges and deliver high-quality software solutions.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
