Senior🎓
Top SchoolGuruprasad Sridharan is a Software Architect with 12 years of experience designing high-performance, data-intensive platforms for real-time and batch workloads. He has built ultra-low-latency systems at PhonePe that process billions of queries daily—authoring a sub-10ms rule engine handling 25K RPS per instance and a JSON-aware real-time storage layer serving 1.7B queries/day with p99 <8ms. Deeply versed in storage internals across relational, key-value, columnar, document and graph models, he routinely combines low-level performance optimization with pragmatic APIs to decouple producers and consumers. He also conceived and implemented PhonePe’s ML platform and batch scoring pipeline integrating Spark and Apache Arrow for efficient Python model execution. Based in Bengaluru, he blends strong academic foundations (BE, 9.1/10) with a hacker curiosity—his GitHub tagline hints at a penchant for big questions even while solving hard systems problems.
