This project involves a large-scale backend data migration and consolidation initiative that supports the modernization of a major retail banking environment. The objective is to migrate and unify data from multiple legacy banking systems into new state-of-the-art solutions hosted on Google Cloud Platform (GCP), enabling improved scalability, consistency, and operational efficiency. The delivery team contributes to the migration of backend data while preserving the existing application architecture, ensuring business continuity and minimizing operational risk. This initiative supports the consolidation of fragmented data sources into modern platforms, improves data accessibility and quality, enhances regulatory compliance capabilities, and establishes a scalable cloud-based foundation for future digital services and advanced analytics. In parallel, the program leverages Agentic AI capabilities to enhance operational efficiency, automate repetitive migration tasks, and improve data validation and reconciliation processes. These capabilities contribute to the development of a large-scale AI Center of Excellence (CoE) focused on data migration and transformation initiatives, enabling standardized automation frameworks, reusable AI-driven components, and scalable best practices across the broader banking technology landscape.
Responsibilities
- Design, develop, and maintain both front-end and back-end components of web applications, ensuring abstraction, code reusability and applying principles like KISS, SOLID and Domain Driven Design. Design, implement, and manage databases using GCP's database services (e.g., Cloud SQL, Spanner). Build and integrate RESTful APIs to enable seamless communication between frontend, backend and other domain microservices. Implement continuous integration and deployment (CI/CD) pipelines using GCP tools like Cloud Build and Cloud Deployment Manager. Ensure application and data security, managing GCP IAM roles and adhering to best practices. Monitor application performance using GCP tools (e.g., Cloud Monitoring, Cloud Trace) and optimize for cost and efficiency. Work closely with cross-functional teams (DevOps, Product Owner, Business Analyst) to deliver integrated solutions. Diagnose and resolve technical issues across the full stack, ensuring application reliability. Keep up-to-date with GCP services, tools, best practices and development principles to leverage the latest technology. Thrive in a scaled Agile working environment, collaborating with a global and diverse team.
