    Hi! I am a 3X CTO for successful PropTech, Real Estate, and AI startup companies. I have built products from 0 to 1 and have scaled them into profitable companies with minimal funding. I have experience leading global teams to deliver high-quality scalable products. With 7 years of software & AI experience, I consider myself an expert in the field and am able to leverage my vast network and knowledge base of the industry. Throughout these years, I have cultivated a long-running small and scrappy team that can also be brought in to help deploy products and scale businesses quickly. I built a successful and profitable property management software company, where I led the design and development. As the Technical Founder, I was responsible for delivering for the customers and managing the build of the entire platform. The stack is built using React, Node.js, and Typescript, and utilizes a custom-built ORM. We leverage the Google Cloud using serverless functions, PubSub, Cloud Tasks, and Firestore DB. Additionally, I lead the mobile development arm of Hair Cuttery, the largest private hair salon company in the United States. I am responsible for both their iOS and Android apps and in the past 7 months have taken their iOS app from a 2.5-star rating to a 4.8 star with almost 3k ratings. Similarly, I have taken their Android app from a 2.2-star rating to a 4-star rating with over 100k installs. I’ve worked across all business sizes and have experience working within a team to deliver high-quality products that fit business needs. Having run multiple businesses and startups, I understand how to operate within tight budgets, and get the most out of domestic and overseas developers while building a strong and cohesive culture that truly delivers value for the business.
