Sunny Pradhan

I’m a results-driven Data Engineer & Java Backend Developer with 5+ years of experience designing scalable data pipelines and backend systems. I translate business requirements into high-performance backend solutions and analytics platforms.

In my Java Developer work, I’ve built enterprise-grade RESTful web services and microservices using J2EE technologies, Core Java, Spring Boot, and Hibernate. I also integrate authentication and authorization with Spring Security using JWT and OAuth2, and optimize performance with multithreading, caching strategies (Redis), and efficient database interaction.

I’m hands-on with AWS for scalable deployments and data workflows, including S3, Lambda, API Gateway, Redshift, Athena, and AWS Glue. I’ve designed data access and persistence layers using Hibernate/JPA with optimized SQL queries, transaction management, and reliable persistence patterns.

As a Data Engineer, I designed and optimized SQL-based transformations and Python data pipelines to ingest, clean, and transform data from multiple sources. I also supported BI and analytics by building reporting tables and semantic layers for dashboards and ad-hoc analysis, while collaborating with stakeholders to define measurable KPIs, metrics, and analytical datasets.
