Senior Full-Stack Engineer — Identity, Search & Applied AI Systems
Ten-plus years shipping production software, now spent mostly on the layer underneath the product: search infrastructure, access control, and the AI systems that sit on top of both. I rebuilt Accomplishr's search on vector embeddings and cut response time from 5 seconds to under 200ms — then went and did it again for the community feed.

I'm a senior full-stack engineer based in Moncton, NB, with ten-plus years across backend architecture, frontend delivery, and — increasingly — the access-control layer underneath both. Most of that time has gone into Node.js, Python, and TypeScript backends, React/Vue/Next.js frontends, and the identity plumbing (SSO, SAML, RBAC, OAuth2) that decides who gets to see what.
The last two years pulled me deeper into applied AI: rebuilding search on OpenSearch vector embeddings, building a semantic expert-matching engine on MongoDB Vector Search, and shipping a LangChain RAG pipeline for document intelligence — all inside a product with real compliance requirements, not a weekend demo.
I hold ISC2 and ISO/IEC 27001:2022 Lead Auditor certifications, and a PGD in Cybersecurity and Intelligence Engineering. I care about systems that stay fast and legible as they scale, and about handing off code a reviewer doesn't have to squint at.
