I’m a Senior Software Engineer with 5 years of experience designing scalable distributed backend systems and microservices using Java, Spring Boot, and Apache Spark. I focus on system design, scalability, performance optimization, and delivering highly reliable production-grade applications.

I’ve built and modernized complex systems in the financial and healthcare domains, including legacy monolith modernization and processing large-scale datasets (7M+ records). I’m particularly proud of work that improves processing efficiency, reliability, and data fidelity in mission-critical workflows.

At HighRadius, I architected and optimized backend workflows for a Java-based financial reconciliation engine, and engineered scalable import/export modules using microservices-based design principles. I also improved frontend responsiveness by upgrading state management and UI components with React, Redux, and TypeScript, and I led cross-functional debugging to resolve production bugs, security vulnerabilities, and performance bottlenecks.

Earlier, at Nference, I designed distributed data pipelines with Apache Spark and PySpark to process 7 million+ healthcare records securely across GCP and Azure, building robust Python ETL workflows that cut downstream analytics processing time by 85%. Before that at Oracle Financial Services, I helped modernize core banking systems by migrating 23,000+ Java components from a legacy monolith into a decoupled microservices architecture, while also automating build and deployment workflows to reduce manual effort by over 80%.
