Most Bubble io apps fail not because the platform is limited, but because of messy database logic, poor mobile responsiveness, or "spaghetti" workflows that break under pressure. If you are tired of buggy bubble io MVP or slow performance, you don’t just need a bubble io developer, you need a Product Partner.
I specialize in transforming complex ideas into scalable, high performance web and mobile applications using Bubble io. Whether you are a startup founder looking for a 3 weeks MVP or an established business needing to automate internal tools, I ensure your app is secure, fast, and pixel perfect.
Core Expertise & Solutions
- Full Scale MVP Development: From a blank canvas to a market-ready product in weeks.
- AI Powered Workflows: Deep integration with OpenAI (ChatGPT), Anthropic, and custom AI agents.
- Performance "Rescue" Missions: Optimizing heavy searches, Auditing and fixing slow, buggy apps to optimize speed and user retention.
- Advanced API & Payment Mastery: Seamlessly connecting Bubble to Stripe (Subscriptions/Connect), Google Cloud, Xano, and custom REST APIs.
- Mobile First Design: Ensuring a native feel experience across iOS and Android using Bubble’s modern responsive engine.
- Existing App Audits: Taking over "broken" projects, debugging, and scaling them to handle thousands of users.
Industry Experience
I specialize in high stakes builds where architecture matters:
- SaaS & Marketplace: Multi tenant platforms with complex user permissions.
- Fintech & E-commerce: Secure payment gateways and automated billing.
- Healthcare: Booking systems and HIPAA-aware data management.
- Internal Tools: Custom CRM/ERP solutions that replace expensive subscriptions.
The Tech Stack:
- Core: Bubble io (Expert level)

- Automation: Make, Zapier , n8n
- Specialties: AI-powered SaaS, Marketplaces, Fintech Dashboards, and CRM systems.
Why Clients Choose Me:
I don’t just "drag and drop." I build with the MVC (Model-View-Controller) pattern in mind to ensure your app doesn't break when you hit your first 1,000 users. My focus is on clean UI/UX and logic that actually makes sense for your business goals.
