It is an analytics Platform which provides performance of different healthcare practitioners Used across all analytics teams inside Athenahealth., Developed a Druid refresh utility which helped non-prod environments to refresh data in significantly less time (i.e from 3 hrs to 15 mins) and optimised the cost (i.e saved 1000$ on every refresh). Developing a self service platform to meet dashboarding and data visualisation needs of data analysis and owners for effective analytics and reporting. Part of crucial project involving shutting down a legacy dashboard called SentinelMetrics Dashboard that incurred a huge tech debt (memory usage: 7.6TB, 14.48 rows, precompute time:10 hrs daily primary transactional database)while successfully moving all clients onto data visualisation platform actively evaluating scaling and performance needs. Researched and modified critical functionalities targeted towards facilitating and improving the performance and effective source data partitioning for queries run across clinical practicers on Apache druid (query ET initial: 30s, after 20s) Assisted extensive testing and stabilisation of the datalens platform run on top of an Apache Druid cluster. Worked on AWS lambda and step function to improve and develop a server-less ETL pipeline for the platform.
