Professional Experience
Legacy Migration Platform
Batch migration platform designed to move legacy operational data into a modern PostgreSQL schema with reliability, security, and auditability.
Inside the build
- Implemented checkpoint-resume flow and dry-run modes for safer long-running migrations.
- Added target schema preflight validation to fail fast before writes.
- Built normalization logic for inconsistent source data and idempotent upsert patterns.
- Secured PII fields with encryption and key-management aware configuration.
