Rahul Agarwal
17 years building and scaling infrastructure across Yahoo, Visa, Flipkart, and Truecaller — from petabyte Hadoop clusters to continent-spanning cloud migrations. Now channeling all of it into Cloptima.
cloptima.ai Founder
AI-native cloud spend intelligence for engineering teams. Cloptima connects to your AWS, GCP, and Azure accounts and turns raw billing data into decisions — unified cost dashboards, per-query cost tracking for BigQuery and data warehouses, automated PR cost-impact comments on GitHub, and Kubernetes rightsizing with confidence scores.
When a deploy spikes costs, Cloptima traces it to the exact commit. When a dashboard query starts scanning terabytes, it flags the pattern before the monthly invoice surprises you. It delivers intelligence where your team already works — through an MCP server for AI agents, a CLI for terminals and CI/CD pipelines, and native Slack and Jira integrations.
Truecaller
Led the Cloud & Data Platform infrastructure team — built the modern Truecaller app infrastructure on GCP. Migrated the entire data infrastructure (hundreds of TB) from on-premise in Sweden to Google Cloud in Mumbai — continent to continent, over the wire. Built and managed the Truecaller Pay architecture, transitioning from monolithic to containerized micro-services and achieving an 80% reduction in infrastructure costs. The data platform ingesting billions of events on Kafka, processing on Hadoop, and reporting on BigQuery — all built by our team.
Flipkart
Led a talented team to scale data infrastructure to an 800-node Hadoop cluster managing petabytes of data — all on an internal private cloud built in-house by Tech@Flipkart. Tackled massive data volumes, reliability challenges, and optimized performance for analytics, fraud detection, and month-end-closure reporting across diverging and often competing internal teams.
Visa
Enhanced the data analytics platform, working on Big Data systems handling billions of daily event ingestions. This was the era when enterprises adopted the Hadoop ecosystem in a big way.
Yahoo
Managed high-performance systems and contributed to Yahoo's vast, complex infrastructure. Worked on Yahoo! HotJobs and Yahoo! Travel properties — deep dives into reliability, scale, and operational excellence.
