Bubble io Expert | Security, Performance & Workflow Optimization
I help founders and teams build, fix and scale Bubble apps that are secure, fast and ready for real users. For over 4 years I've worked on large, complex Bubble projects, the kind with heavy databases, many workflows, multiple user roles and integrations. That experience taught me where Bubble apps usually break, slow down or leak data, and how to prevent it. What I can do for you: Security audits and testing: privacy rules, exposed data, API workflows, user roles and permissions. I find the gaps before someone else does. Performance optimization: faster page loads, leaner searches, better database structure and lower Workload Unit consumption. Workflow optimization: cleaning up and restructuring backend and frontend workflows so they're reliable, maintainable and cost-efficient. Bug fixing: tracking down the issues that are hard to reproduce and fixing them at the root, not with patches. Infrastructure and architecture: planning how your app should be built so it scales without needing a rebuild later. Fast AI-assisted development: I use AI tools in my workflow to ship features faster without sacrificing quality. How I work: I don't just execute tickets. I understand product, so I'll ask about your users and your goals, and I'll tell you when there's a simpler or better way to get there. I communicate clearly in writing, keep you updated daily.
