  • Codifying best practices for future reuse in the form of accessible, reusable patterns, templates, and code bases to facilitate meta data capturing and management
  • Managing a team of software engineers writing new code to build a bigger, better, faster, more optimized HTAP database (using Apache Spark, Apache Arrow and a wealth of other open source data tools)
  • Interacting with exec team and senior engineering leadership to define, prioritize, and ensure smooth deployments with other operational components
  • Highly engaged with industry trends within analytics domain from a data acquisition processing, engineering, management perspective
  • Understand data and analytics use cases across Web3 / blockchains
