Enabling complex joins between datasets and faster iteration of ML models for an AI tech company


Client Background

Client is an AI technology firm that helps large enterprises integrate data from a variety of sources and build their machine learning models both faster and more precise


  • The application hosts hundreds and thousands of datasets (either free or paid) sourced from thousands of providers.
  • Enable the enterprise users, decision scientists, and data analysts to upload their organizational datasets.
  • Facilitate joins between the uploaded transactional/non-transactional datasets and the other publicly hosted datasets.
  • These joins should be executed within a few seconds for seamless user experience.


  • Implemented responsive and modern frontend app for data scientists using Redux React.
  • Designed and implemented all middle-tier services that include APIs and data access layer on Python Django
  • Wrote ANSI SQL code generator in Python that considers all user selections, connects with the metadata system, and generates the final query that runs on Snowflake.
  • Built search and recommendation systems on Neo4j that help users find features pertinent to their own uploaded datasets.

Tools & Technologies

Numpy, Django, Redux, React, AWS, Snowflake

Key benefits

  • Snowflake allows complex joins that include running various math functions between large datasets to happen within seconds, giving an output of billions of rows
  • It auto-creates multiple clusters depending on the count of concurrent queries as the workload increases
  • Data Scientists can quickly iterate over their models and thus move towards higher accuracy levels since they now save a significant amount of time finding the most relevant features.
