Develop software for semiconductor manufacturing equipment across multiple tool types and customer deployments. Build WPF-based desktop applications to enable communication between user interfaces, PLCs, and hardware modules via gRPC. Implement SECS/GEM host communication (SEMI standards E5, E30, E37) for seamless tool-to-factory integration. Design a modular, service-oriented, event-driven architecture (factory design patterns), manage system data using MariaDB/MySQL, and complete multiple short-notice deployments at a leading semiconductor customer site in Singapore, including cleanroom troubleshooting and performance tuning. Lead/assist technical customer meetings to gather requirements and train international operators on equipment software.

Built WPF-based desktop applications for semiconductor automation tools, enabling communication between user interfaces, PLCs, and hardware modules via gRPC. Implemented SECS/GEM host communications following SEMI standards (E5, E30, E37) to support seamless tool-to-factory (Host/MES) integration. Designed modular, service-oriented, event-driven factory architectures; managed system data using MariaDB and MySQL. Completed short-notice on-site deployments for an international semiconductor customer in Singapore, including functional demonstration, in-cleanroom troubleshooting, and performance optimization. Lead technical customer meetings, gathered requirements from customer engineers, and trained international operators on equipment software. Delivered end-to-end solutions including a reusable secure file transfer utility using SSH.

Built a real-time notification feature for WSO2 Choreo using Azure Service Bus and WebSockets. Conducted performance testing with JMeter and optimized scalability. Developed a GramaNiladari administrative web app (proof of residence, police and identity checks) using React, Ballerina, WSO2 Choreo, and WSO2 Asgardeo for authentication; also used Nginx and integrated supporting services for deployment.
