I am a full-stack developer, specializing in mobile (iOS/Android), Wordpress and Social Media Marketing. After years of working with overseas Developers to help me build my very own startup, I noticed that besides being able to find Devs at a fraction of the cost, the majority of Devs found did very unprofessional work, they were not organized, did not test and had weak code/design skills. So where do bootstrapped startups go to develop their MVP's? I decided to be part of the solution. I now work with an amazing team of highly skilled developers/designers that understand the startup culture and specialize in fitting within a bootstrapped budget. I have experience working with startups; I’ve attended Founders Space, one of the top Incubators in the country based in San Francisco. Myself including our team have a wealth of knowledge when it comes to building a startup from an idea to a reality.

I build things that give people more freedom—financially, creatively, and within their communities. My career started outside of tech as a content production manager in the self-help industry, where I scaled a business from the ground up by listening to customer feedback, refining every part of the process, and creating high-impact products that resonated with a niche audience. That instinct for problem-solving carried over into software, where I’ve spent years turning nebulous ideas into technical products—some for clients, some for myself. I help founders and organizations bring their ideas to life with minimal risk and maximum impact, setting them up with the right processes to gather feedback, iterate, and grow. I don’t cling to any particular approach—whether it’s open-source models, peer-to-peer protocols, or novel hardware. What matters is reaching people where they are and building technology that works for them.

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.

Building efficient MVPs for early-stage startups. As a full-stack developer with over seven years of experience, I specialize in creating scalable apps for mobile and web platforms. I have helped non-technical founders build apps for their startups that have been accepted into top startup accelerators like YCombinator and TechStars. Three main reasons why building an MVP is a great idea: ⏱️ It Is Faster: Creating an AI-powered MVP takes less than two months, allowing you to quickly validate your concept and identify your product market fit. 💵 It Is More Cost-Effective: Compared to the cost of developing a full-scale app, an MVP can save you up to 200%. 💰It Is Profitable: Developing an MVP can help you secure a startup accelerator acceptance or raise a pre-seed/seed investment round. In today's market, investors typically require startups to have a validated product and traction rather than just an idea. My full-cycle MVP development service includes UX/UI design, full-stack development, QA testing, and post-launch support. Please feel free to contact me for more information.

Extensive success developing on the iOS platform for personal projects, individual clients, and startups. My background in tech started over 5 years ago as a high-schooler customizing Shopify sites for my e-commerce ventures. I would then go all in on iOS development in early 2021 to bring my ideas to life through the iOS platform. Today, my main focus is still on personal projects while contracting in the background. With proficiency in Swift and SwiftUI, here is what I can do for you: - Build a modern application from scratch - Revive, update or fix existing applications - Integrate new or existing applications into popular back-ends like Firebase - Get previously stalled app development efforts to the finish line - Consult on feature possibilities, App Store Connect, etc. My process: 1. Briefing / Discussions 2. Research 3. Design 4. Integrate 5. Revise 6. Release I work with the most fluent and up-to-date languages/frameworks in order to provide a rich and fresh user experience. My most commonly used tech stack is Swift, SwiftUI, and Firebase. Recently, I have been working with AVFoundation to create custom camera modules for personal and client applications.
