Bhagya entered our team with the very challenging task of supporting a legacy C++ codebase used by a lot of challenging customers with very high support expectations. Simply said, Bhagya´s tenacity and drive exceeded everyone´s expectations. After a few weeks on the job, everyone on the team felt reassured and confident, which was a primary factor to making the whole project a big success.

      The Salvation Army AUGUST 2022 – CURRENT Designed and mentored developing a reusable metadata driven ETL Framework that ingested data from source systems to landing, staging, data vault and data mart layers using Azure Synapse Pipeline/ADF. This was a greenfield project. • Lead the development of the ETL Framework and its orchestration with Synapse Pipelines • Ingestion layer supports REST API, SFTP and ADLS storages with the ability to extend to other methods. • Developed staging pattern, automated data validation and issue reporting mechanisms that were used across the project. • Developed data vault hub, link and satellite loading patterns. • Developed fact tables loading pattern in the data mart layer for “as was” presentation of the data. • Advocated and established Git and CICD processes within the project. • Mentored junior data engineers to establish engineering practices like naming conventions to deliver project objectives. • Managed stakeholder expectations to achieve project objectives. • Tech stack includes Azure Synapse pipelines, SQL, Azure DevOps, GIT and Python Department of Environment, Land, Water and Planning MARCH – AUGUST 2022 Worked with DELWP to migrate the on prem ETL system on to Azure cloud. On prem system used SSIS packages and they were migrated on to ADF and SQL Managed Instances. • Developed ADF data pipelines to execute SSIS packages • The sensitive information and the variables that change across different environments (dev, UAT and prod) were stored in Azure Key Vault. • Developed a notification framework using Azure Event Grid, which enabled triggering additional ADF pipelines upon successful completion of a given pipeline.

      Research topic: Merging data from different sources to generate synthetic agent populations.The research explores novel methods to construct synthetic human populations by fusing marginal data distributions from different sources, like census data. The work:• Reconstructs the information lost during the data collection process. For example, family andhousehold structures in census data.• Merges existing populations that contain partial information to construct new populations with complete information.• Proposes suitable statistical tests for comparing very large categorical distributions consistingcategories of varying sizes, by doing a detailed analysis of test behaviours under different conditions.• Algorithm development included efficient memory usage, dynamic programming, Monte-Carlo simulation and optimisation techniques to deal with exponentially growing solution space.• The word advances agent based modelling and simulation technology by providing reliable methods to generate highly detailed agent populations.
