Software Developer II at Deep Sync building an AI conversational analytics service and a platform for 50+ services.

India

Message

At Deep Sync, I'm building a Spring Boot platform that serves as a single entry point for 50+ independent services, with shared authentication, multi-region, and multi-tenancy capabilities. I also launched a conversational analytics service that lets people query StarRocks DB in natural language, with privacy enforcement and interactive visualizations.

I built an AWS analytics platform using S3, Parquet, and Athena, including a secure aggregation API with caching that achieved sub-5-second p99 query latency while reducing data scan costs. I also developed a DuckDB-based deduplication service that reduced costs by 110%+ compared with existing EMR-based solutions.

At MasterCard India, I developed an Android SDK prototype for NFC Tap-to-Pay, card provisioning, P2P, and e-commerce payments, and an MCP server for Agentic Commerce. Earlier, I maintained an event-streaming platform used by 1,000+ internal applications and resolved a production bug that improved response time from one minute to 10 seconds.
