Have a great idea for a web or mobile app but not sure where to start? I specialize in designing and developing apps from scratch for entrepreneurs. Book a consultation today to strategize the best way to bring your idea to life! -Top 1% in app design & development by Upwork -Trusted by Harvard, Yamaha, UC Berkeley & Samsung -Clients' apps have raised +330M USD and made it to Forbes. About a decade ago, I launched my own application and startup called SchooLinks with no tech background... Hired the wrong freelancers, used the wrong tech stack, and made many other expensive mistakes along the way. I learned that "cheap" can be expensive in app development. I also learned how to effectively validate your idea before building an app— a crucial step that many people tend to overlook. While anyone can design or code, very few can create products that actually help you test if there's a market for your idea. This is critical when developing MVPs (Minimum Viable Products) and POCs (Proof of Concepts), where the right approach can make the difference between success and costly failure. After 2 years, I was able to finally launch SchooLinks. It has raised over $90 MM USD and became the industry leader of its category. This experience led me to want to help other fellow entrepreneurs and business owners avoid the expensive mistakes I made. I went back to school at UC Berkeley, where I became the VP of Technology for Entrepreneurial Association. During my time there, I helped dozens of startups launch their apps! As a result, I created Geekbears, my app design & development agency. Our clients have raised over $350 MM USD with web and mobile apps we helped them launch. You can count on me being upfront when I don’t think we are a good fit and point you in the right direction. Schedule your consultation today! My preferred tech stack includes: Figma, Flutter, NodeJS, Angular, AWS & MongoDB. I also have solid experience integrating API’s, including Stripe, ChatGTP and Twilio.
