Website: https://linktr.ee/YoKulGuy --- 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. I do research and craft code as my way of expressing my idea and belief. I crafted a scientific computation tool and instrument to help researchers do better research when I was in college. I led a team in a startup called Mekari to empower businesses in Indonesia. I previously worked at Midtrans, enabling software developers to be more productive and better empower commerce through technology. I write production code in Elm, JavaScript, Bash, Ruby, and Java. In 2020 I did functional programming on Elm and built a community around it. Feel free to reach out to me if you are an Elm user!
