Build anything.
Prove it works.
AI systems, trading infrastructure, formally verified software, and secure deployments. Local. Private. Mathematically proven.
And if you just want to know how to use it — reach out. We teach too.
What we build
End-to-end systems across AI, finance, formal math, web, and security.
AI Systems & Infrastructure
Local LLM deployment, GPU clusters, model fine-tuning, and AI pipelines. On-premise or cloud. Private and self-contained.
Trading & Financial Systems
Algorithmic trading systems, broker integrations, backtesting engines, and real-time market data pipelines.
Formal Verification & Proofs
Machine-checked mathematical proofs and formally verified software. Published work across Lean, Coq, Isabelle, and more.
Web & Application Development
Full-stack web applications, APIs, dashboards, and mobile-ready platforms. Modern frameworks, fast delivery.
Security & Air-Gapped Solutions
Air-gapped AI systems, secure infrastructure, network hardening, and compliance-ready deployments.
Who we serve
From personal projects to institutional infrastructure.
Why Constant Systems
