UTKARSH SANDEEP SINGH

I’m a Senior Backend Java Engineer with 6+ years designing scalable enterprise applications using Java 17, Spring Boot, microservices, REST APIs, and Kafka. I focus on high-performance distributed systems, asynchronous processing, multithreading, and cloud-based integrations.

At Ernst & Young LLP, I engineered a relationship calculation engine using graph traversal algorithms, built reconciliation services with SQL optimization and JPA to achieve a success rate of 95%, and developed asynchronous Excel/CSV pipelines with Spring @Async and Apache POI to reduce completion time by 40%. I also integrated Java microservices with Python-based document extraction and reconciliation via REST APIs, Azure Form Recognizer, and intelligent document processing.

Previously, I built and supported tax e-invoicing solutions with REST APIs, schedulers, Docker/CI/CD, and OpenAPI/Swagger documentation to improve client integration. Earlier roles included improving microservice communication reliability, running testing/debugging to boost stability, and delivering knowledge transfer that reduced support inquiries by 15% and increased user adoption by 20%.

Alongside my backend work, I’m currently pursuing MTech in Artificial Intelligence and Data Science Engineering at IIT Patna. I aim to bring the same analytical rigor to data-driven systems—bridging robust engineering with AI-enabled intelligence.
