About

Hey thanks for visiting my profile. This is me in short:- Backend and distributed systems software engineer working on Salesforce Data Cloud, focused on building scalable, reliable activation pipelines for enterprise customers. At Salesforce, I work in the Activation team where I design and implement data workflows that process millions of records per activation across multi-tenant environments. My work spans Java, Spring Boot, Apache Spark, and PostgreSQL, with a strong emphasis on correctness, performance, and fault tolerance that support AI-driven engagement and personalization use cases. Key contributions include: • Building Activate on Engagement, enabling tenants to trigger activations using Engagement DMOs forming the data backbone for AI-powered decisioning and insights within Salesforce Data Cloud. • Implementing incremental refresh support for updates and deletes, handling large-scale deltas efficiently in Spark-based pipelines. • Improving reliability of GCS, SFTP, and Azure activations from 99.8% to 99.9% by strengthening retries, validation, and failure handling Previously, I worked at InfoEdge where I built and optimized backend systems using Java, Kafka, and SparkSQL, improving latency, scalability, and system reliability across high-traffic products. I’m interested in backend, platform, and data infrastructure roles where I can work on large-scale distributed systems and solve complex data problems.
