Banking
Core tech migration and Agile transformation
Migration of a banking product from a monolith to microservices, with continuous delivery and regulatory compliance in a highly demanding environment.
Through an iterative and incremental development approach and an emergent architecture defined alongside product growth, Grupo Esfera accompanied the bank in its technology migration. Mixed multidisciplinary teams—composed of bank personnel and Esfera team members—worked alongside Technical Agile Coaches to sustain multiple weekly releases, even amidst changing regulations and less flexible core systems.
Summary
Migration to microservices without disrupting banking operations

Challenge
The client needed to migrate a legacy product to a new tech stack, modernizing its components to regain adaptability and meet business and regulatory requirements. The challenge included maintaining quality within a strict compliance environment and coordinating continuous delivery alongside less flexible core banking systems.
1
Obsolescence and technical rigidity
Need to migrate a monolithic system to microservices to gain maintainability and flexibility.
2
Banking environment and strict compliance framework
Coordinating frequent releases while coexisting with less flexible legacy core systems and highly demanding, changing regulations.
3
Gap in roles and decision-making
Traditional working dynamic that lacked cross-functional roles for prioritization and decision-making in continuous delivery cycles.
4
Need for reskilling
Requirement to train client personnel in new technologies, methodologies, and collaborative dynamics between business and technology.
Solution
Emergent architecture and co-creation
Using the Esfera Way as a framework, Grupo Esfera deployed a comprehensive strategy based on iterative and incremental development, with an emergent architecture defined as the product grew. The migration was sustained by mixed multidisciplinary teams—composed of bank personnel and Esfera team members—supported by Technical Agile Coaches, who drove the adoption of best practices and strategic decision-making without disrupting banking operations.
