Is slow legacy infrastructure or fragmented data holding your business back?
With 14+ years of enterprise architecture experienceincluding multi-cloud migrations across AWS, GCP, and Azure for global e-commerce platforms and fintech systemsI will seamlessly transition your data stack to a modern cloud environment with zero data loss and minimal downtime.
Core Expertise: Multi-Cloud Migrations: Database transitions to Google BigQuery, AWS (RDS/Redshift), and Azure (Synapse/Databricks). Schema Redesign: Translating legacy relational models into scalable, cloud-native architectures. Security & Compliance: Complete encryption (at-rest/in-transit), RBAC enforcement, and PCI DSS compliance.
Migration Process:
- Discovery & Assessment: Audit current database structures and operational bottlenecks.
- Architecture & Mapping: Design target cloud data models and secure migration pathways.
- Execution & Validation: Perform schema creation, initial data loads, and delta syncs.
- Performance Tuning: Optimize query execution and indexing before final handoff.

FAQ
1. Will my application experience downtime during the migration?
No. I utilize a dual-phase sync approach (historical baseline load followed by delta/change data capture) to ensure zero to minimal downtime, scheduling any final cutovers during your lowest-traffic hours.
2. Which databases and cloud platforms do you work with?
I migrate legacy sources like SQL Server, Oracle, MySQL, and PostgreSQL to modern cloud warehouses including Google BigQuery, AWS (RDS/Redshift), and Azure (Synapse/Databricks).
3. How do you protect sensitive data during transfer?
I enforce enterprise-grade security protocols, including end-to-end data encryption (at-rest and in-transit), Role-Based Access Control (RBAC), and PCI DSS compliance standards.
4. Do you just copy the raw data, or optimize the schema?
I redesign and optimize your legacy database schemas into cloud-native structures (using professional ERD modeling) so you get maximum query performance out-of-the-box.
5. What do you need from me to begin?
Read-only access or schema documentation for your source database, an estimate of your total data volume, and details on your target cloud account (or I can help you set one up).
