AI capability / future project lab
AI OCR is one project. The bigger direction is AI-enabled internal tools.
AI OCR is one applied project. The broader direction is using AI to turn internal tools into smarter assistants for knowledge retrieval, workflow support, and operational automation.
Current applied work sits on AI OCR, RPA, and workflow automation. The planned lab projects extend that base into agents, retrieval, and OCR-to-RPA demonstrations.

Murata Electronics Singapore (Pte.) Ltd.
C# / .NETBPRAI OCRRPAAWS Migration
- Optimized a C#/.NET WinForms data-generation workflow by consolidating AS400 access into a small set of joined queries, replacing repeated linear lookups with hash-map indexing, and introducing a concurrent Java retrieval service—reducing processing for 26,000 records from about five hours to under 20 seconds.
- Maintained and enhanced existing C#/.NET WinForms desktop applications, migrated selected systems to Java-based web applications with Next.js or Thymeleaf interfaces, and planned phased modernization for remaining systems.
- Conducted BPR for existing internal systems to improve productivity, operational efficiency, and user experience.
- Developed internal business applications for ASEAN and India affiliates.
- Migrated legacy systems toward modern AWS cloud-native architecture.
- Implemented AI OCR and supported RPA workflows for business process automation.
