I was born in Balige, a small city on Lake Toba, Indonesia. I came to the USA as a graduate student and completed my PhD degree in Computer Science. I have worked in the Information Technology industry for 20 years and it is time for me to contribute more to the society by creating a startup company called Maduma LLC that will developed software products partly around Balige and provide scenic tourism service for tourists living in American and other developed countries to enjoy the beauty and unique culture of the people around Lake Toba.


You are invited to own shares of Maduma LLC by investing in the company; or if you are not interested in the investment but you would like to support my mission, please help by donating any amount of fund. Any amount will help. 

Over the years, I have developed two software products: a smart personal knowledge management system (Bisuk) and a smart-and-super-efficient time logging system (Tikki). I have used Bisuk for 20 years and it is so good that I cannot live without it. I have used Tikki for 4 years which allowed me to log and analyze how efficient my time has been spent. I need the raised fund to write patents, polish the software, enhance the software, market the software products and the tour services, evaluate and plant guided tours.  

The third software product (Ula) will be developed, utilizing the core intelligent of Bisuk and Tikki, to help job seekers find relevant jobs as well as companies find qualified candidates. The fourth software product (Tarombo) will be developed to preserve the unique culture of the Batak people who mostly live around Lake Toba. Tarombo will be free for anyone and profits will be gained from advertisements.

Again, please help achieving my noble dream by either investing in the company or donating to the cause. Thank you.
