As an innovative, analytical, and technology-driven professional with over 15 years of experience in software engineering, frontend solution architecture, I am ready to deliver immediate and long-lasting results as a Software Developer. I bring a strong architectural mindset, hands-on technical expertise, and a track record of successfully delivering scalable, maintainable, and high-performing systems across diverse industries, including banking, SaaS, healthcare, and education.
In my current role as a UI Engineer at the Bank of Singapore, I have been instrumental in modernising the Relationship Manager Front-End (RMFE) dashboard. I led the migration to a micro-frontend architecture, enabling seamless integration of independently deployable components across teams. This approach significantly improved scalability and maintainability, while also supporting multi-tenant capabilities. To establish a cohesive design system, I implemented Material UI themes powered by design tokens and integrated Tailwind CSS, ensuring consistent styling, accessibility compliance, and brand alignment across components. Furthermore, I introduced Webpack Module Federation to facilitate dynamic runtime loading of shared modules between micro frontends, empowering faster development cycles and enhanced modularity.
Before joining Bank of Singapore, I worked for over six years at Softcodeit Solutions, where I served as a Technical Lead Engineer. In this role, I led cross-functional teams to design, develop, and deploy a variety of web applications using a range of technologies including ReactJS, NestJS, AngularJS, and Laravel. I oversaw all stages of the software development lifecycle from architecture and coding to testing and deployment. I managed project planning, sprint cycles, and CI/CD pipelines while upholding best practices in clean code, version control, and documentation.
One of my key achievements during this tenure was the development of an internal platform called SCIT Team App, designed to facilitate team coordination and performance tracking. I was responsible for designing the system architecture and developing the core modules, including user management, task tracking, and analytics dashboards. I also played a pivotal role in building a tailor-specific SaaS platform aimed at US-based tailor shops. This system enabled inventory management, customer scheduling, and order tracking, and was widely appreciated for its intuitive UI and robustness. In another project, I designed and implemented a gamified engagement platform called iPlayDeal, balancing performance and user interaction to drive engagement.…As an innovative, analytical, and technology-driven professional with over 15 years of experience in software engineering, frontend solution architecture, I am ready to deliver immediate and long-lasting results as a Software Developer.
