Portfolio

A Comparative Study of Data-mining Techniques for HCV Patients’ Data

I applied various data-mining techniques on Hepatitis C patients’ data for observing the high prevalence of risk of the Hepatitis C virus. The results obtained by the applied algorithms of this paper were superior to other techniques found in related research papers.

ETL Migration from DataStage to SSIS

During this project, I migrated an entire ETL implementation from IBM DataStage to Microsoft SSIS and ensuring that all the business rules were intact.

Reusability of Data Marts

I created a generic data mart based on the source system which were deployed to multiple clients for meeting the required reporting purposes with little customization (if needed) on the reporting end.

Managed Services

I led a team of consultants on a project for managed services for production monitoring of EDW loads over nightly builds and resolving the errors—if any—on level-1 and level-2 tiers.

Data Engineering for AI Models

I engineered the data to give it a more suitable form for modeling machine learning algorithms. I also created a mechanism for data gaps and performance monitoring of AI models.

Design and Implementation of a Data Warehouse for a SaaS Platform

After researching and understanding the system, I designed, developed, fixed the bugs, and optimized the performance of a type of SaaS-based multi-tenant risk and compliance software—enabling the reporting feature on the top of it.
