The Challenge
NexaBank was running on legacy on-premises infrastructure that was struggling to keep pace with rapid digital growth. Their systems faced frequent downtime during peak periods, compliance audits were becoming increasingly complex, and the engineering team was spending 70% of their time on infrastructure maintenance rather than product innovation.
Our Solution
We designed and executed a phased migration to AWS, implementing a microservices architecture that decoupled core banking functions. A zero-downtime migration strategy ensured customers experienced no service interruptions throughout the 18-month engagement.
Our Approach
Discovery & Architecture
Conducted a thorough audit of 200+ legacy services, mapped data flows, and designed the target-state cloud architecture with security and compliance at the forefront.
Foundation & Security
Established AWS landing zones, implemented IAM policies aligned with PCI-DSS and SOC 2, and set up centralized logging and monitoring pipelines for stronger visibility and governance.
Phased Migration
Migrated services in priority order using a strangler fig pattern, ensuring each service was validated before proceeding. Zero production incidents across all migrations and deployment phases.
Discovery & Architecture
Tuned auto-scaling policies, implemented FinOps practices, and delivered comprehensive training to the internal engineering team for smoother long-term cloud management and ownership.
