I'm a senior AI engineer with over 8 years of experience building intelligent systems and machine learning solutions that transform how businesses operate. My journey in AI began with fascination for neural networks and has evolved into expertise in designing scalable, production-ready AI systems. I specialize in deploying machine learning models, with deep expertise in applied AI techniques like RAG, MCP and toolings. When I'm not tackling models, you can find me researching cutting-edge AI techniques, contributing to open-source ML projects, or mentoring aspiring engineers.

When a production data pipeline crashes on regulated customer data, engineers can't ask for logs and customers can't share samples. This is about David's design for capturing debuggable signal — deterministic tokenization, structural metadata over raw values, and a key-rotation architecture that lets historical logs decay into cryptographic noise — plus the trade-offs it deliberately accepts.

You cannot reliably detect where an LLM runs inference. Any product claiming otherwise is overclaiming. This is about the Aegis design decisions that required admitting limits — the residency model built on declared metadata and fail-closed routing, the multi-tenancy deliberately deferred, and why the non-goals list is as load-bearing as the feature list.

A guardrail that silently runs at reduced fidelity is worse than no guardrail, because you've stopped watching. The hardest design problem in the Aegis rewrite was keeping safety honest under streaming. Here is the four-verdict model, the capability negotiation that resolved the streaming conflict, and how the same contract ends up governing tool calls.

The first version of Aegis worked, and that was the problem. Every governance feature was hardcoded into one request path, so every change was a core change. This is the story of throwing out the architecture and rebuilding around a small kernel and seven plugin contracts — what that bought, what it cost, and the decisions I'd defend.
