Isaias David C.

Full-Stack SaaS Developer | Node.js, Stripe, Firebase & AI Automations

I help founders and businesses build web platforms, internal tools, and AI automations, and bring existing projects to production when they're ready for real users. If you've already started with AI tools or a prototype, I can help you take it further: adding secure payments, user management, third-party integrations, and the production layer needed to handle paying customers reliably. What I build: - SaaS platforms with user management, Stripe subscriptions, and production backends. - Custom internal tools and project management systems tailored to specific workflows. - AI-powered solutions using computer vision, OpenAI/Claude APIs, and automated workflows. - Multi-service integrations connecting Stripe, Firebase, SignWell, Cal, WhatsApp, and similar tools. How I work: I use AI tools (Claude Code, Cursor, n8n) to move fast, and review and test everything manually before shipping. I work asynchronously through written communication and deliver on schedule. Send me a message with your project details and I'll be glad to help.
