Not just impressive demos.
Systems people can depend on.
My work sits at the platform layer beneath AI products: model access, retrieval, evaluation, observability, safety, and developer experience. I care about the paved road - the reliable defaults that let teams move faster without losing quality or control.

Selected work.
Idiongo
A private, multi-tenant workspace where organisations talk, learn, and grow. I own the AI platform beneath the product: provider routing, workspace-isolated RAG, prompt governance, Sentinel moderation, AI course generation, Tutor, and Care Triage. Selected details are shown with permission while the product remains in stealth.
LegalRAG
Retrieval infrastructure rebuilt around evaluation and citations, lifting accuracy from 29% to 96.7% with structured logging, cost tracking, and full test coverage.
CDEPF
Cross-domain ensemble probability fusion for phishing detection, reaching 94.4% accuracy and a 64.3% relative gain over baseline.
InsightFlow
Communication intelligence that turns emails and meeting transcripts into structured, decision-ready briefs with an AI-optional, rules-first pipeline.

Let’s talk
Tell me what you are building, where it is stuck, and what success looks like. The usual first step is a focused architecture conversation, then a scoped sprint or platform engagement.
