Hi, I'm Sai Sandilya V

Building scalable Java and Spring Boot backend systems for retirement-plan platforms, with recent work across batch processing, service migrations, and test coverage.

• Led a batch-processing redesign with Java 21, Spring Boot, Confluent Kafka, Virtual Threads, AWS EKS, Kubernetes, and KEDA autoscaling.
• Achieved 300% higher throughput and reduced batch execution time by 50%.
• Developed RESTful APIs for income-goal projects supporting high availability and data accuracy for 1M+ retirement plan participants.
• Migrated workloads from Spring 5 to Spring 6 and JDK 8 to JDK 17, improving reliability, compliance, and performance by up to 2x.
• Improved SonarQube coverage from 7% to 80% with unit and integration testing practices.

Delivered backend and workflow enhancements across Java, Spring Boot, JavaScript, FTL, ETL, and internal platform modernization work.

• Implemented functional enhancements across UI workflows, forms, export features, ETL improvements, and internal tooling.
• Migrated an internal application from WebLogic to Tomcat, eliminating license costs and improving operational efficiency.
• Contributed to internal framework modernization, reducing technical debt and achieving a 35% performance improvement.

Built cloud-migration proof-of-concepts and backend notification services while transitioning from internship work into production engineering.

• Developed cloud migration POCs by moving on-premise services to AWS Elastic Beanstalk.
• Integrated Spring Boot APIs with Unqork to accelerate internal-tool delivery.
• Built a JavaMail and Spring Boot notification service with SMTP configuration and templated batch alerts.
