I am a software developer from Malaysia. I have more than 17 years in software development. I started programming as a profession in C and slowly transition into web application development in .NET. After more than 4 years programming in .NET, I started exploring Java programming until now. Recently, I am learning Phyton and Go programming. I have experience developing applications in both monolith and microservices architectures. Below is my experience during 17 years of software development;
