Oct 2022 – Dec 2023 · 1 yr 2 mos · Bengaluru, Karnataka, India · Hybrid

Worked as a consultant on a MySQL to Oracle data migration for a core banking client (UBCI, Tunisia).
Performed post-migration data validation — row count reconciliation, financial balance checks, and referential integrity analysis ensuring zero data loss.
Documented MySQL to Oracle schema mapping including data type conversions.
