IndiaWhat I'm looking for
At Vantive Healthcare, I lead the design of scalable full-stack applications using React.js, Node.js, and AWS. I built event-driven file-processing systems that improved ingestion performance by 400% and developed large-scale data pipelines with PySpark, AWS Glue, and Redshift.
Previously at Oracle Data Cloud, I developed distributed client-facing applications and redesigned REST APIs into GraphQL schemas to improve performance and flexibility. I also built Node.js backend services, optimized React applications with Redux, and created Python monitoring tools for AWS S3 data pipelines.
Across Johnson Controls, First American India, Xerox Business Services, and UST Global, I've delivered backend services, microservices, responsive interfaces, automation frameworks, and cloud deployments. My work includes Django, .NET, JavaScript, React.js, Node.js, Express.js, and AWS.
I enjoy solving performance, scalability, and system-design challenges while driving architecture discussions, mentoring engineers, and collaborating across teams. I focus on clean, observable systems with strong API design, event-driven workflows, and practical cloud-native delivery.
