David O.
Web & App Developer | Bubble, JS, AI, Automation, Xano, Database & API
I’m a Web Developer helping businesses turn ideas into scalable web and mobile applications using Bubble, Html, Css, JavaScript, n8n, AI, automation, Xano, APIs, databases, and no-code/low-code development. With a background in data analysis, I bring a data-first approach to app development. I understand that a reliable, scalable application starts with a well-structured database. How data is organized affects performance, workflows, scalability, reporting, and how easily an app can evolve as a business grows. When I build a Bubble application, I think beyond the interface and consider database architecture, relationships, privacy, workflows, and long-term scalability. I specialize in building Bubble applications from the ground up, including database architecture, UI/UX, complex workflows, API integrations, automation, backend logic, and deployment. Whether you need a Bubble MVP, SaaS platform, marketplace, internal tool, dashboard, automation system, or AI-powered application, I can help.
