Lead technical design for a global tier-1 bank's corporate banking platform with a three-person team of application designers — customer-management, entitlement, notification and reporting services — producing designs the bank's engineers build from directly and walk through together in joint design reviews. Delivered through:
• Designing the services on event-driven microservices
• Writing the AP

Led a three-engineer build team revamping a Southeast Asian bank's corporate-banking entitlement module — user entitlements and approval rules — from a legacy system to event-driven microservices. Delivered through:
• Designing and building the module on event-driven microservices
• Reviewing the implementation with the bank's engineers — data structures, business flows and complex logic
• Trouble

Third year on the same mobile-banking project: took over the delivery-tracking, notification and promotion-CMS services, leading two engineers, and owned defect triage and production support within SLA. Delivered through:
• Implementing new features on the established codebase while keeping backward compatibility
• Running root-cause analysis and shipping code fixes within SLA
• Tuning performance

Second year on the same mobile-banking project: built the REST APIs for the notification, audit-log and approval-rule services as a member of the engineering team. Delivered through:
• Bringing an engineering perspective to the application designers' API documents, closing the gap between complex technical specs and what was implementable
• Implementing the technical designs within the established

First year on a mobile-banking project serving tens of millions of customers: built Spring Boot REST APIs for the terms-and-conditions, transfer and foundation services as a member of the engineering team. Delivered through:
• Implementing the technical designs within the established architecture, tech stack and principles — REST APIs, table schemas and event consumers
