What I'm looking for

I’m looking to build and optimize manufacturing test software—ATE integration, data collection, and reliable inspection systems—while collaborating with R&D and production teams to improve throughput, quality, and test coverage.

I specialize in designing and developing customized software solutions for manufacturing industries, including automated test systems, data collection systems, manufacturing traceability, and report generation. I bring strong expertise in audio and video test methodology, machine vision systems, and database management.

Over the years, I’ve developed and refined test software across multiple platforms using C++, C#, Python, and Java. I work with concurrent programming, dynamic compilation, and asynchronous executions to test multiple products across threads/cores.

I’m also well-versed in communication protocols such as CAN bus, UART, GPIB, Ethernet, and socket protocols. On the data side, I design database applications and configuration database management systems using SQL Server, SQLite, and MySQL.

Currently, I run my own company delivering custom software solutions for electronic manufacturing in Penang. My recent work focuses on integrating manufacturing equipment with information systems (AOI, X-Ray, ICT, functional testers), building downtime monitoring, and transferring complex R&D test solutions to production teams.
