About this Gig
Legacy database and desktop systems holding your enterprise back? I migrate them to secure cloud.
The software your business runs on costs more than its license fee. Slow queries, no concurrent
access, no API layer, no audit trail and an IT team spending 30% of its time keeping it alive.
Legacy modernization is the prerequisite to every digital initiative on your roadmap.
As a Database Architect, I handle the full migration lifecycle from assessment to production
with zero data loss and full operational continuity during transition.
What I build:
Legacy assessment Microsoft Access, dBase, legacy SQL, desktop apps, old ERP systems
Schema modernization normalized PostgreSQL on Supabase, optimized for enterprise scale
Supabase Auth + Row Level Security role-based access replacing legacy permission systems
Data migration full ETL pipeline, integrity validation, and zero-downtime cutover strategy
Admin dashboard operational interface replacing the legacy UI your team depended on
Old system decommissioned. New system live. Your team keeps working throughout.
Message me with your current system and team size I'll scope the migration within 24 hours.

FAQ
Can you migrate from Microsoft Access, dBase, or legacy ERP systems?
Yes. Microsoft Access, dBase, legacy SQL Server, old ERP exports, and desktop application databases are all supported. I handle schema translation, data type mapping, relationship normalization, and a full ETL pipeline with integrity validation before any cutover. [253/300]
How do you guarantee zero data loss during a live enterprise migration?
I run migrations in parallel — old and new systems operate simultaneously during a validation window. Only after full data integrity verification and team sign-off does the cutover happen. The legacy system remains live until your team confirms the new one is correct.
Can our team keep working normally during the migration?
Yes. The migration runs against a staged environment in the background. Your team operates the legacy system as normal until the validation window closes and cutover is scheduled. Downtime is typically under 2 hours for the final switch
What does Supabase Row Level Security replace in a legacy system?
Most legacy systems enforce access in the application layer — easily bypassed. Supabase RLS enforces access at the database level: the right data is physically unreachable by unauthorized users regardless of application logic. It's the upgrade most legacy migrations skip.
Do you rebuild the admin interface after migrating the backend?
Yes. The Premium tier includes a full custom admin dashboard replacing your legacy UI — same workflows, modern interface, role-based access tied to your new Supabase Auth layer. Your team works the same way; the infrastructure underneath is entirely modernized.
