I'm a realist, aspiring general system thinker, and software craftsman. Despite specialists giving much contribution and productivity to society, general system thinkers and their general system thinking can help us solve the second-order effect of human creation.
As a society, we build civilization; we build skyscrapers, aeroplanes, gadgets, and all the advancements in technology, but we overlooked the second-order effect of our creation. Global warming and gadget addictions are an example to name a few.
The more people adopt general system thinking, the more we can achieve a better society and brings our world to the next thousand years.

Hello! If you need help with game development, I'm here to help you find (and learn) effective techniques and solutions for your projects.
As a mentor, I can help you with **Technical Guidance** (assistance with coding, debugging, optimization), **Design Insights** (feedback on mechanics, level design, UI), **Asset Advice** (guidance on using time-saving assets/tools), and **QA** (thorough testing and bug tracking), among other topics.
I can answer questions on topics such as **Development Challenges** ("How can I optimize my game for better performance?"), **Design Decisions** ("How to improve the game UX?", "What mechanics can make my gameplay more engaging?"), and **Troubleshooting** ("Why is my game crashing on startup?", "Why is my game build failing?", "How do I fix this bug in my C# code?"), among other topics.
