As a life-long entrepreneur and developer, I have had the opportunity to work in the software industry in various capacities for more than 15 years. This journey has provided me with a wealth of experience and a front-row seat to the evolution of cutting-edge technology.
Throughout my career, I have embarked on a transformative journey, transitioning from primarily working as a Ruby developer to specializing in React/frontend development over the past five years. This shift has not only broadened my skill set but has also propelled me into the dynamic world of web3. The realm of web3 presents a newfound source of inspiration and countless opportunities, which I am wholeheartedly embracing alongside my ongoing JavaScript journey.
I pride myself on being highly motivated, creative, and efficient. I possess a keen eye for user experience and have developed a deep appreciation for the intricate nuances of human-machine interaction design. My ability to balance between technological innovation and user-friendly interfaces is a core strength.
For those curious about my work, I have been involved in notable projects such as the 'F1 project,' for which I have provided an in-depth explanation here: https://www.youtube.com/watch?v=O6BXm0Yg9f4
