Gian S.

Certified Bubble Developer

I design and build scalable SaaS platforms, internal systems, and high-performance MVPs using Bubble. With experience delivering production-ready applications for international clients, I focus on clean architecture, optimized data models, secure workflows, and seamless API integrations. My approach goes beyond building features, I structure systems that scale. What I specialize in: • Scalable SaaS architecture & relational data modeling • Payment systems (Stripe, subscriptions, identity verification) • Advanced API integrations (OpenAI, external services, automation) • Performance optimization & server-side best practices • Mobile-first responsive dashboards • Automation-driven workflows I’ve worked on multi-user platforms, payment gateways, AI-powered applications, and complex data systems, always prioritizing long-term maintainability and scalability. If you’re building a product that needs to scale, not just launch, let’s talk.
