Field notes from the platform.
Architecture case studies from the work — enterprise RAG platforms, agentic AI, micro-frontends, and platform consolidation. Each one starts with a failure, then the fix. RSS →
TOGAF, applied for real. When the method is load-bearing, not decoration.
One tailored pass through the TOGAF 10 ADM, run on an agentic audit platform built solo inside a 48-hour window. Interactive: every phase, principle and governance step opens. The argument is not that the documents impressed anyone — it is that the method caught its own architect being wrong three times, on the record.
Read →The arithmetic decides. Where the model may not go in a money-moving agent system.
Four bounded agents, hybrid RAG with a citation guard checked in C#, fourteen deterministic invariants and a hash-chained ledger — and the design line the whole thing stands on: the model reads, retrieves and explains; the arithmetic decides.
Read →Making enterprise RAG a platform, not a project. What broke when every team built their own.
The retrieval framework behind 20+ production AI workflows at a Fortune 500 enterprise — hybrid retrieval that survives identifier queries, entitlement filtering pushed inside the query, a semantic cache that knows when it’s lying, and the workflow registry that turned a library into a platform. Closes on why an FMCG promotion peak — Black Friday — is the honest test of whether any of it holds.
Read →Building agentic AI for healthcare: lessons from HealthQCopilot.
Why a hallucination guard against FHIR became the most important agent in the system, what the work taught us about prior-auth, and the orchestration patterns that survived contact with real clinicians.
Read →Shipping a micro-frontend shell on Module Federation. The contracts that kept it sane.
Why the registry and design-system packages matter more than the remotes themselves, the runtime errors that nearly killed the rollout, and the team-topology pattern that made independent deploys actually safe.

Consolidating an enterprise platform onto HotChocolate behind Azure APIM — including the directive design that finally made field-level authorization survive a security audit.
