Details of Work History

1. Blockchain (from late 2016)
   • Worked on building P2P protocols to store and route decentralised data
   • Implemented several Algorithms for chunking and storing data in Swarm
   • Data pinning in Swarm
   • Wrote FairOS ( decentralised database over Swarm)
   • Built the backend of a centralized exchange
   • Worked in Proof of Stake (Consensus Layer)
   • Protocol Research in Shardeum Layer 1
   • Building an STM-based parallel transaction processing in EVM (multi-threaded EVM).
2. Big Data Analytics
   • Implementation of Analytics suite using CDRs
   • Used MapReduce (Hadoop) and HDFS to re-design several Big data systems
   • Built Large scale OLAP cubes for about 1 billion unique products
   • Product search using Solr
   • Designed API to serve 50 billion records of PayPal’s Merchant data
3. Neural Networks
   • Curated test data and trained CNN to classify products based on images
   • Product similarity using CNN and similarity models
4. Telecommunication
   • Implementation of various protocols like V5.2 ans SS7
   • Involved in early standardisation of 3G HSDPA
   • Implementation and bug fixing of Motorola MSC (about 10 million lines of code)
