About Toni Ruokolainen
Meet Toni Ruokolainen, Ph.D. and Principal Architect helping Healthtech and SaMD engineering organizations anchor their AI coding agents in mathematical determinism.
I’m Toni. Let’s stop your coding agents from hallucinating clinical logic.
If your product squads leverage AI agents without machine-enforceable regulatory boundaries injected directly into your SDLC today, they will invent rogue clinical rules, risk compliance breaches, and instantly compound technical debt.
As a Founder and Principal Architect with a Ph.D. in Computer Science, I bridge the gap between formal methods, systems modeling and modern AI-assisted software delivery. With over 15 years of deep technology research and a decade of hands-on industrial pragmatism as a Researcher, Product Manager, and Solution Architect, my focus is singular: stopping AI coding tools from breaking your strict regulatory constraints.
The Compliance Illusion
You know that AI-accelerated tools (like Cursor or Claude Code) massively increase feature velocity. But LLMs predict code based on statistical probabilities, whereas Healthtech and SaMD organizations operate on strict, deterministic invariants. Without mathematically governed boundaries, your AI tools will inevitably introduce "rogue compliance logic", inventing unauthorized ePHI data paths and clinical workflows.
This creates a massive Senior Engineer Tax. Your most expensive talent is forced to manually untangle hallucinated regulatory rules in code review just to keep you audit-ready.
The Principal Architect Philosophy
I started my consulting practice to solve this specific gap. I do not sell open-ended advisory retainers or probabilistic "prompt engineering"; I deliver deterministic engineering systems.
- The 14-Day Architectural Build: I bypass bloated transformations. Through a rigorous, fixed-scope 14-day build, we isolate a core regulatory slice and extract your clinical knowledge into a formal, executable domain model.
- Mathematical Determinism: I wire this formal, executable domain model directly into your SDLC. Powered by rigorous domains-specific modeling and formal methods (including the Z3 Theorem Prover), I build the automated local verification gates that force your AI to self-correct against FDA/MDR reality, automatically generating a Compliance Bill of Materials (CBOM) for every execution.
- Air-Gapped Delivery: I operate on an entirely air-gapped integration model, allowing me to deploy architectural safety without triggering multi-month InfoSec vendor audits.
Engineering Precision & IP Ownership
Because I map your core regulatory rules, I build directly alongside your platform engineering or development team. Arvoan operates on an "Outputs vs. Engine" IP model: you retain 100% ownership of all customized deliverables, including the formal, executable domain model, guardrail configurations, and the Architectural Evolution Runbooks.
