• ● Led the e2e architecture & development of Search Ingestion team.
• Created a DSL driven, multi-tenant Generic Entity Ingestion framework that can ingest
• heterogeneous entities to different kinds of sinks in Flipkart (like Search Index, Data
• Platform, Kafka, Pulsar) via streaming & batch modes of Ingestion.
• Made our BatchIngestion framework(MapReduce), generic & multi-tenant to ingest data to
• different destinations. Performed various Optimizations to improve runtime & performance
• of the MapReduce jobs
• Impact:
• Reduced Batch Ingestion duration by ~60% from 6hrs to 2.5 hrs
• Reduced RAM usage of our Yarn/Hdfs cluster by 20% & the no. of Yarn workers
• Used by: Search for Grocery, 2gud, Shopsy | Recommendations | Order Search | Product Features for ML models | Knowledge Graph building
• ● Improved delivery speed perception in Search Results to show delivery sla in Search result tiles
• Built an In-memory store, following a shared-nothing design, using a simple ConcurrentHashMap with optimized memory usage . Each VM could store ~250M listingId*pincode => SLA entries
• Build a throttled async fetcher that fetches SLA from PromiseEngine APIs & stores in the
• in-memory store along with a deduper.
• ● Led the development of Image Search ingestion & serving
• ●Tech stacks: Extensively worked on HBase, Storm, Kafka, Redis, Airflow, RocksDB with a very good understanding of those.
• ● Love to work in high-scale distributed systems, solving complex tech problems.
• ● Other skills : Hadoop ecosystem, MapReduce, RocksDB, Microservices, Performance Optimizations.
• ● Have experience working on Infra & highly scalable distributed system applications

• Blackbuck is an industry leader in the B2B truck logistics domain and my team handles stuff like invoicing customers, tracking couriers, payment collection & doling out Incentives & Referrals.
• Projects:
• 1. The process of soliciting payments from Customers once an Order is completed was done manually via spreadsheets initially .I designed & developed a workflow from scratch, wherein the process of getting the Customers to pay is streamlined.
