Senior Software Engineer at Highradius building fault-tolerant distributed workflows and cutting Snowflake compute costs by 50%.

India

Message

At Highradius Pvt Ltd, I refactored distributed workflows with the Saga design pattern and implemented throttling and idempotent APIs for reliable pipeline processing.

I integrated Spark with Kyuubi-based computation to migrate non-human interactions using Iceberg and Nessie, eliminating 50% of Snowflake compute costs. I also architected a DAG-based coordination service and implemented real-time event delivery with Redis pub/sub.

At Brane Enterprises Pvt Ltd, I developed event-driven microservices and dashboard APIs for enterprise tenants, and implemented tenant isolation and automated data archival.

On the blockchain team, I owned the private blockchain module end-to-end, reducing database calls by 30% and API response time by 25%. Earlier, at Truminds, I integrated RabbitMQ, built a Node.js REST API for IoT devices, and developed an automated number plate recognition system.
