01 / About
Experience with a
builder’s mindset.
I’m a software developer based in Malaysia with extensive experience designing and developing business applications for manufacturing and enterprise environments.
Over the years, I have worked across the full software development lifecycle - from business requirements and database design to APIs, enterprise integration, deployment and production support.
My experience spans .NET, C#, Java, Android, Flutter, SQL Server, SAP integration, SharePoint, cloud technologies and increasingly, Generative AI. Outside professional work, I enjoy building my own apps and experimenting with new technologies.

Enterprise Manufacturing Systems
Business & manufacturing applications
Developed and supported enterprise applications used in manufacturing environments, including warehouse automation, asset management, approval workflows, mobile warehouse applications and manufacturing systems.
05 / Current direction
From software
engineering to AI.
I’m exploring how AI can move beyond chatbots and become part of real business workflows. My focus is Agentic AI - systems that understand tasks, retrieve information, use tools, make decisions within defined boundaries and complete useful work.
AI Agents
Agents that interact with business systems and perform multi-step tasks.
RAG
Connecting LLMs to company knowledge so answers use relevant business information.
Enterprise AI
Applying AI to manufacturing, finance, HR, logistics and other processes.
AI Automation
Reducing repetitive manual work through intelligent workflow automation.
ALSO EXPLORING
On-premise AI
Locally hosted LLM solutions where privacy, infrastructure and data control matter.
06 / Ideas in motion
AI experiments

A working notebook of possible tools and directions. These are ideas and experiments, not claims of finished commercial products.
AI AP Clerk
Automating document extraction, invoice processing, validation and workflow routing.
Manufacturing AI Assistant
An internal assistant for manufacturing processes, systems, documentation and operational knowledge.
AI Document Processing
OCR + LLM pipelines for extracting structured information and starting downstream workflows.
AI Mobile Applications
Small, focused AI-powered mobile applications that solve specific everyday problems.
07 / The journey
A long view of
building things.
2000s
Started software development
Began building business applications and developing experience across engineering, databases and enterprise systems.
2010s
Enterprise & mobile development
Expanded into enterprise systems, manufacturing applications, Android development and system integration.
2020s
Enterprise modernization
Worked with modern enterprise technologies, SAP integration, cloud systems and large-scale manufacturing projects.
Today
AI + independent products
Combining traditional software engineering with Generative AI, Agentic AI and independent product development.
