Hi, I'm Darshan

Mumbai, India | Open Source Platform Builder

Philosophy

Build tools that solve real problems at scale. Ship beats perfect - but data accuracy is non-negotiable when 1.2 billion requests depend on it.

Random Facts
  • The CSC database started as a side project - now it powers apps in 100+ countries
  • Developed a triangular user network algorithm using Neo4j graph database
  • Run the entire CSC platform solo: database, API, export tool, docs, packages, website
  • Powered by chai, not coffee
