    • 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
