• Designed and built payments infrastructure on AWS integrating crypto gateway (BVNK) and banking providers, routing transactions dynamically by investment product, increasing total trade value and user capacity. • Automated end-of-day transaction file retrieval. Replaced a manual reconciliation step and ensure our financial records are consistently synced without human intervention. • Built end-to-end KYC pipeline serving Hong Kong, Malaysia, and Latin America, integrating third-party verification providers and reducing manual review workload by 56%. • Shipped Claude-powered agentic AI into production to orchestrate share dealing, balance validation, and order execution scaling to thousands of daily requests with fault-tolerant, real-time order processing. • Architected event-driven microservices on AWS with Kafka, ensuring high availability and consistent state across regulated financial operations spanning multiple regions.

* Refactored and migrated monolith into microservices running each service in docker container for improved scalability, portability, and resource utilisation. * Personalised notification system - Implemented a solution to synchronise a video stream with audio, enabling customised audio playback upon the triggering of alarm notifications. - Verified the extension and content of audio files using Apache Tika prior to upload. * Dark Mode Support - Transformed the product's user interface paradigm by introducing Dark mode, enhancing visual appeal and user experience, while aligning with current design trends and standards. * Configuration push/pull - Developed a UI for configuration and template creation, creating reusable generic components to promote efficient code reuse and maintainability. - Built an API wrapper layer to translate data into JSON format payload to transmit data between different systems * Identified the limitations for improvements and bottlenecks in the legacy implementation and proposed revamping using the latest technologies for improved user experience and performance. * Engineered customer-facing web portals using React.js, Ext.js, Java Spring Boot, PostgreSQL and Highcharts for real-time monitoring of video live streaming quality. * In Agile development environment, actively contributed to designing components, their functionality, and facilitate discussions on use cases. Additionally, assessed architectural designs for technical feasibility with architectural leads, ensuring that the development process remained agile and adaptive to changes.

* Migrated FusionCharts to HighCharts and utilised pd4ml to capture chart snapshots, enabling the creation of PDF documents with ease in a short period of time as browsers were ending support of flash player. * Contributed to the development of an in-house UI library, crafting reusable generic components that fostered efficient code reuse and enhanced existing in-house generic components by adding valuable features, elevating the overall capabilities of the library, - Implemented Debouncing and Throttling techniques which resulted in better UX and page load performance. * Collaborated seamlessly with cross functional product team members to drive the successful implementation of new feature developments, while maintaining close coordination with development and QA teams in a fast-paced development environment.

* Created an advanced and sophisticated database upgrader tool - Ingested high volume data, out of which required data was fetched, parsed and updated. * Implemented an API for transmitting Heartbeat and Sparkler events
