Overview
Cloud Transformation Helped Vira eliminate 15 years of fragmented legacy infrastructure, migrating 500,000 documents to a cloud-native platform with 99.9% accuracy and zero downtime in 90 days. System response times dropped from 2–4 minutes to sub-5 seconds through a fully rebuilt, governed cloud architecture.
The Challenges
15 years of case data trapped across fragmented legacy systems, country-specific Excel sheets, and disconnected document stores with no cloud infrastructure — 2–4 minute loading times, no unified access layer, and zero data governance across multiple countries were symptoms of infrastructure that had never been modernised.
Migrating 500,000 documents and years of historical case data to a modern cloud platform without business interruption required a transformation strategy that could handle complex multi-system ETL, schema unification, and zero-downtime cutover simultaneously.
Solution
Architected a cloud-native data platform on Supabase and PostgreSQL — replacing 15 years of fragmented legacy systems with a unified, cloud-hosted single source of truth, engineered from a ground-up schema that mapped every legacy data structure into a coherent, governed architecture.
Engineered a comprehensive ETL pipeline to extract, clean, transform, and migrate 500,000 documents and all historical case data with 99.9% accuracy — maintaining complete data integrity and document fidelity throughout a zero-downtime cutover across multiple country-specific systems.
Implemented cloud identity and access management via Microsoft Azure SSO with full role-based access control — centralising authentication and access governance across multiple countries, user roles, and case types in a single enterprise-grade identity layer.
Delivered a cloud infrastructure eliminating all legacy technical debt — reducing system response times from 2–4 minutes to sub-5 seconds through cloud-native architecture, optimised data models, and purpose-built indexing across 500,000 documents and 100,000 cases.
