About Me
I'm a Fullstack Developer at PT Hartono Istana Teknologi (Polytron Indonesia), with experience developing and maintaining enterprise applications across Sales, Warehouse Management, After Sales, and Production. My work focuses on building reliable applications, improving system performance, and streamlining business processes. I've contributed to application performance improvements of up to 20–50%, warehouse automation initiatives that reduced stock-checking time by 50–80%, and RPA implementations using Microsoft Power Automate. I have also been involved in introducing AI-assisted development practices through internal training and knowledge sharing. Outside of software development, I enjoy exploring hardware, building PCs, and helping others find suitable computer setups based on their needs.

What I Do
Testimonials
“Mr. Angga taught me the fundamentals of programming (DDP). Honestly, he used a lot of analogies and real-life examples to simplify programming concepts, which made it much easier for me to understand things quickly, especially since DDP covers the very foundations of programming. He was also always willing to provide one-on-one tutoring whenever he had free time. The programming mindset and fundamental concepts he taught me have stayed with me and continue to be useful to this day, even though my current background is in data analytics. Wishing you all the best, Mr. Angga! 🔥🔥”
