After working 30 years in software development, PKI (Public Key Infrastructure), and lately involved in the blockchain technology, I think I am an old seasoned stone in the field where I am at.Recently, I have been designing new application models on top of blockchain, the one being the calorie coin, and music coin, and a few others. It has been absolutely fun, and exciting in this new genre of software, thanks to Satoshi. Last decades my experiences have been built around the online transactional services security, and was interested in smaller devices, more so due to the prospect of the IoT.I have been a Senior Architect, Evangelist, Strategist, & Major Account Sales for last few years,with the specialties in:1. Blockchain application model development and implementation,2. Architecture of online security with Public Key Infrastructure, 3. Applications of biometric and motional authentication, 4. Implementation of online financial services with strong authentication and security, and 4. Architecture of IoT security in smart embedded devices (such as smart cars and smart meter).I am an art lover (classical music, photography, & fine art), and a sports fanatics (golf, jogging, & hiking). I am a hard-working, self-motivating person with young inquisitive mind. I don't fear sacrificing my time for others. I am bilingual between Korean and English.
