Case Studies

Selected architecture work.

Each is a system I designed and shipped, not a demo.

Regulated Banking / RAG

Production RAG for a core banking suite

Banking clients needed faster, accurate answers from data spread across structured and unstructured sources, inside strict compliance boundaries.

I designed and built the retrieval architecture from scratch: ingestion, embedding, and vector search pipelines powering LLM-driven Q&A, with evaluation loops and audit trails.

Knowledge retrieval efficiency up ~35%; manual query resolution time down ~40%.

Platform / Model-agnostic

A provider-independent LLM gateway

Vendor lock-in is a strategic risk in regulated finance — and frontier models change monthly.

I architected a model-agnostic gateway so the platform routes across frontier and open-source models, with fallbacks and per-model cost and latency attribution, without application rewrites.

Models become a configuration choice, not a re-platforming project.

Agentic / Reliability

Durable, auditable agentic workflows

Agent pilots dazzle in demos and collapse in production — infinite loops, hallucinated tools, partial completion.

I built agentic execution on durable workflows with explicit guardrails, human-in-the-loop checkpoints, and full observability for non-deterministic behavior.

Agents that an auditor can trust and an operator can run.

Security / Governance

Security architecture as the default

As project security leader I embedded data privacy and compliance into the architecture rather than reviewing for it later.

Security and compliance were design inputs from the first diagram — not a gate at the end of the release.

Vulnerabilities down ~25%, with regulatory compliance maintained across releases.
