➡️ 12 years in startups ➡️ $25 million acquisition ➡️ Led marketing ➡️ Led operations ➡️ Now leading technology ➡️ Head of a team of 5 extremely talented, hand-picked developers I started my career as the non-technical cofounder of multiple startups. After my third project was acquired (we developed a video baby monitor with breath detection), I took the opportunity to solve the #1 problem that had plagued me through my first endeavors--unreliable communication and delivery from my technical cofounders, employees and contractors. I spent several years learning how to be my own technical co-founder and build now on a stack of React Native for the front end and Xano for the back end. In addition to guiding clients on how to most efficiently invest in their tech products, I also offer unlimited marketing and operations consulting at no additional cost because the more successful my clients are, the more successful I am. While doing work for a limited number of clients, I also have working on my own projects a small team of developers I hand-picked from the tech scene in Ecuador where I spend part of the year. Great news for my clients because I can scale up and scale back technical development on demand and have access to advanced expertise in security, LLMs, data science, etc.
