• Architected and developed high-concurrency, low-latency fund systems projects using SOFABoot framework, integrating critical middleware components including MQ, distributed transaction (XTS), Redis and scheduler job. • Served as project lead for over 6 major initiatives, each exceeding 200 man-days in scope, driving end-to-end delivery from technical design through production release. • Responsible as fund domain system owner, overseeing system stability, performance optimization, and long-term architectural evolution. • Led technical risk analysis for core financial systems and produced actionable optimization proposals to mitigate risks and improve system resilience. • Designed and delivered the site-level wallet integration architecture, serving as the primary technical liaison with third-party partners for API design and protocol alignment. • Drove deep resolution of complex financial workflows including institutional reconciliation, top-up refund recovery, and fund traceability processes, ensuring accuracy and compliance across settlement cycles. • Pioneered adoption of AI Agent tooling such as CodeFuse CLI within the team, accelerating development and troubleshooting workflows with measurable efficiency gains of 10 engineering man-days project cycle. • Conducted code reviews to uphold code quality standards and technical knowledge sharing with the team. • Reviewed system’s three axe elements, which can be monitored, grayed, and rolled back. Ensure that the impact of control errors is minimized in production release.

• Engineered backend services for inter-bank and intra-bank fund transfer modules, ensuring secure transaction processing in compliance with banking-grade security and regulatory standards. • Partnered with business analysts to translate complex business requirements into detailed technical specifications, ensuring alignment between stakeholder expectations and delivered functionality. • Collaborated with geographically distributed development teams across Singapore and China, including Host and SOA teams, to deliver integrated banking solutions. • Designed and implemented microservice-based architecture using Java Spring Boot, achieving measurable improvements in system scalability, modularity, and deployment independence. • Played an instrumental role in database schema design and enforcement of code quality standards. • Delivered end-to-end technical support encompassing shell script automation, centralized log analysis via Kibana, and systematic debugging of defects identified during QA and UAT cycles. • Authored comprehensive unit and integration test suites using Mockito and JUnit 5 frameworks, achieving 100% code coverage targets. • Implemented event-driven architecture leveraging Apache Kafka for asynchronous inter-service communication, enabling real-time notification delivery and parallel transaction processing. • Managed continuous integration and deployment pipelines via Jenkins across multiple environments (DEV, SIT, UAT, PROD), ensuring reliable and repeatable release processes.

• Served as the primary technical liaison between engineering, business analysts, and product owners, translating business requirements into scalable technical solutions to drive customer satisfaction. • Authored and maintained API specification documents adhering to OpenAPI standards, enabling seamless integration workflows with partner development teams. • Collaborated with cross-functional development teams to design and implement new features and modules, applying clean architecture principles and SOLID design patterns to ensure long-term maintainability. • Developed and enhanced RESTful APIs using Java Play Framework and Spring Framework within an MVC architecture, delivering high-performance backend services for mobile wallet and digital payment platforms. • Actively contributed to database schema design discussions, business logic, and implementation planning, incorporating design patterns such as Strategy and Factory to produce optimized and extensible solutions. • Orchestrated production deployments via Jenkins CI/CD pipelines, implementing blue-green deployment strategies to minimize downtime and ensure reliable release processes. • Diagnosed and resolved daily production issues through systematic log analysis in Elasticsearch and Kibana, reducing mean time to resolution for critical ad-hoc incidents.

Deep explored into developing back-end using Java, Spring Boot and Hibernate framework. Developing front-end using Angular framework and Angular UI libraries.
