    When I was 19, I started my first business in technology. I was under-prepared and had lacked the necessary knowledge. However, I loved staying up working on something I could truly call mine. While the business eventually did not work out, I learned invaluable lessons about work ethic, objectivity, and most importantly perseverance. These important skills would be instrumental in guiding me throughout my career as an entrepreneur, software engineer, and investor. With every failure and challenge that I faced, I learned to overcome them by believing in myself, which allowed me to grow both personally and professionally. Now four companies later, I am still the same enthusiastic person staying up all night to learn. I enjoy creative thinking, problem-solving, and leading teams to success. I am currently a Senior Software Engineer at Facebook, where I learn from the best and brightest. I am incredibly fortunate to be working in such a prestigious company with so many stellar engineers. I am able to learn from everyone's insights as well as share my own hard-won experiences. I'm open to new business ideas and ventures with like-minded individuals. Feel free to reach out if you think I could be valuable to you.
