Description

Scope

• The Office of the Public Guardian and Trustee (OPGT) requires a Senior Software Developer ETL to perform data migration activities from the existing OPGT legacy applications to the new Dynamics 365 OPGT solution and data warehouse/lakehouse.

Assignment Deliverables

As a member of the data migration team, you will be responsible to migrate the data from the existing OPGT legacy applications to the new Dynamics 365 OPGT solution and the new data warehouse/lakehouse. A high-level list of deliverables for the data migration team follows:

• Data Analysis: analyze the existing data in the legacy applications, understand its structure, quality, and relationships and help in designing an appropriate migration strategy;
• Data Mapping and Transformation: map the data elements from the legacy application to the corresponding entities and fields in Dynamics 365 CE, F&O and Data Lakehouse. Handle necessary data transformations, ensuring compatibility and consistency between the legacy data and the target system;
• Data Extraction: help extract the required data from the legacy application, develop and implement extraction processes to retrieve data from various sources, such as databases, files, APIs, or other relevant legacy systems;
• Data Cleansing and Validation: cleanse and validate the extracted data to ensure its accuracy, completeness, and consistency. Help with identifying and resolving data quality issues, performing deduplication, and applying business rules to ensure the integrity of the migrated data;
• Data Migration Strategy and Execution: review the present migration strategy that outlines the overall approach, sequence, and timeline for migrating the data from the legacy application to Dynamics 365 using a delta-load approach; execute the migration plan efficiently, managing data transfers and ensuring minimal disruption to ongoing operations;
• Data Testing and Quality Assurance: conduct thorough testing to verify the accuracy and integrity of the migrated data; define test cases, perform data reconciliation, and address any issues or discrepancies that arise during the testing phase; develop KPIs to report on the progress, completeness and quality of the data migration effort;
• Documentation: document the entire data migration process, including data mapping rules, transformation logic, migration scripts, and any specific configurations;
• Ongoing Support: provide post-migration support, analyze and address data-related issues or questions; help optimize data management processes in the new environment;
• Data Lakehouse: help expand the current data lakehouse implementation and help build a gold layer for reporting; conduct data analysis and profiling; develop data transformation and cleansing pipelines; implement data integration and harmonization;
• Other duties as assigned;

The Vendor's Personnel will also be required to:

• Complete work and achieve milestones within the assigned deadlines;
• Notify the Cluster/Ministry project Manager in writing of any issues or other material concerns related to the Assignment Deliverables, as soon as he/she becomes aware of them
