I am preparing to move a sizeable MySQL dataset—customer, product, and transaction records—to a new environment and need someone who has performed full-scale migrations before. The assignment runs for roughly one month, during which you will work from our Hyderabad office so we can iterate quickly with business owners and IT. The work covers the entire pipeline: extracting data from the current MySQL instance, scrubbing and de-duplicating it, mapping old structures to the target schema, and applying significant transformations to fit new business rules. Solid SQL is obviously essential, and you should already feel at home with large tables, indexes, constraints, and performance tuning. Experience scripting in Python or using ETL utilities (e.g., Talend, Pentaho, custom shell/Python pipelines) will make life easier because several transformation rules are complex. I will provide full access to the existing database schema, sample data, and the target data model on day one. Throughout the month you will collaborate with our in-house QA team to validate row counts, referential integrity, and transformation accuracy. Deliverables (all must be completed before sign-off): • Detailed mapping document linking each source field to its destination equivalent • Reusable extraction and transformation scripts with clear inline comments • A cleaned, fully migrated MySQL database ready for user acceptance testing • Verification report summarising reconciliation checks (totals, counts, spot audits) Success means no data loss, referential integrity maintained, and transformation rules passing our test cases. If you have run similar migrations and can commit to working onsite in Hyderabad for the duration, I’d like to get started right away.
