Message

At Scaledex, I built the core order-processing engine for a multi-tenant ordering platform using Next.js, PostgreSQL, and Stripe. I also implemented real-time order sync over WebSockets and built the core backend for the company’s AI assistant, a RAG system with LLM tool calling.

Through my projects, I’ve shipped Tensorify.io, a visual workflow builder that turns node graphs into runnable Python projects, and Flexx.dev, an MCP server for secure remote development machine access. My research has included 3D CNNs for dental caries classification and RAG pipelines for clinical decision support, with work published in peer-reviewed journals.
