Equational Applications LLC is the personal/studio site of Kurt VanDusen, positioned as the portfolio of a full-stack developer building AI-powered mobile and web applications. The site highlights core areas including React Native, Expo, Firebase, Google Cloud, Vertex AI, and several projects around LLM memory, RAG, local-first knowledge bases, and AI Agents.
The standout project is Clanker, an open-source AI character chat platform built in public. It supports custom characters, persistent memory, image generation, cloud-based character saving and sharing, subscription-based access control, and coverage across iOS, Android, and Web. Its backend uses Firebase and Cloud SQL/PostgreSQL; the AI layer involves Vertex AI and Anthropic Claude; and payments are handled via Stripe. Other projects include an Expo LLM Wiki built with TypeScript + SQLite, a local-first Tauri/Rust second brain, a marketing Agent based on Vertex AI Agent Builder, a Dockerized RAG Chatbot, and a bridge integration from Firebase Auth to Supabase Session. Overall, the tech stack is strongly developer-oriented and focused on practical engineering implementation.
Several projects on the site include GitHub links, and Clanker is explicitly labeled Open Source. The RAG Chatbot is described as Dockerized and runnable locally, while Curated Thoughts emphasizes a local-first approach. However, there does not appear to be unified product documentation, API documentation, deployment guides, or a commercial support policy. As a result, it is better suited for developers with engineering capability to reference or build upon, rather than as a polished, ready-to-use SaaS product.
The official site does not disclose consulting service rates. Clanker mentions subscription-based access control and Stripe subscriptions, but does not provide specific subscription prices, plans, or supported payment regions. If considering it for outsourcing or consulting work, you would need to contact the owner directly to confirm scope, timeline, pricing, and maintenance arrangements.
Its strengths are broad technical coverage, real and transparent projects, and hands-on practice across AI, mobile, cloud backends, and payment flows. Google Cloud certification also adds credibility. The downsides are limited commercial information and the lack of customer case studies, SLA, pricing, and complete documentation. It is a good fit for founders and technical teams that need AI app prototypes, React Native cross-platform development, Firebase/Google Cloud integration, or experimentation with LLM memory and RAG.
The site does not provide information about access, payments, or compliance for users in China, so china_access can only be marked as unknown. Depending on requirements, possible alternatives include Firebase/Supabase, Dify, LangFlow, Flowise, Vercel, Expo, and similar tools. However, in China’s network environment, the accessibility of cloud services and model APIs typically needs to be evaluated separately.
