Solid systemsProven usefulness

We build custom AI assistants, web applications, APIs, and the infrastructure that powers them. The common denominator is clear data flow, predictable behaviour, and dependable products that ensure success across every goal.

AI-Native
Intelligence used where it creates real value.
Functionally Grounded
Data, effects, and failure kept visible.
Correct by Design
Security and limits shaped before deployment.

What We Build

Focused capabilities for organisations that need useful software without unnecessary layers of process or technology.

AI Assistants & Intelligent Workflows

Customer assistants, document understanding, multilingual interfaces, and carefully bounded automation connected to real business outcomes.

  • LLMs
  • Vision
  • Effect
  • Cloudflare

Web Applications & Performant APIs

Fast websites, product interfaces, and typed APIs built around clear data flow, accessible design, and useful content.

  • Astro
  • TypeScript
  • Workers
  • PostgreSQL

Infrastructure & System Reliability

Deployment, integrations, observability, security boundaries, and maintainable backends with fewer operational surprises.

  • Cloudflare
  • Bun
  • NixOS
  • SOPS

Correctness-Sensitive Systems

Research and prototypes for domains where timing, state, failure, and auditability deserve explicit treatment rather than optimism.

  • Haskell
  • Rust
  • Simulation
  • Testing

The MethodProven in our Work

Hina AI is the flagship product, live on Telegram. Moonray is our market-systems research. Both show how CFMoon applies its engineering standard to its own ideas.

From Problem to Dependable System

  1. Understand

    Clarify the user, outcome, constraints, risks, and what success looks like in practice.

  2. Model

    Shape the data, permissions, workflows, interfaces, and failure modes before implementation hardens them.

  3. Build

    Implement the smallest useful system with typed boundaries, visible behaviour, and restrained moving parts.

  4. Prove

    Validate behaviour, security, accessibility, cost, deployment, and operational handoff before calling it finished.
