AI engineer who owns the whole arc: I embed with customer teams, lead discovery to find the real bottleneck, then design, build, and ship the production system end-to-end — and stay on it through rollout, iteration, and the real-world edges. I've taken a first version from a one-day prototype to a system teams rely on daily, and I care about what survives production, not what demos well. I've also published peer-reviewed research in applied quantum computing. What I build is shaped by the people who use it.
Experience
Zetane Systems Inc.
— MontréalJan 2022 — PresentLead AI Solutions Architect (2025—present) · formerly Software Developer
Joined as an early engineer and grew into the lead on AI solutions and client delivery — from first commit to the source-grounded platform behind the company's first external raise. The two products I'm most responsible for, then the foundations under them.
- 1,900+ commits since 2022
- 253 in the last 60 days

Pomerleau — AI estimating & cost-prediction
sole technical owner · 2022—present · one of Canada's largest construction firms (~$1B revenue)
AI cost prediction (in production): forecasts new-project costs from just two inputs — area + project type. Ensemble of Ridge regressors with per-cohort bias correction, ~12–13% MAPE on a leave-one-out benchmark. In daily use; publicly announced by Pomerleau.
Full estimating stack: interactive plan takeoff (PDF overlay, automatic corner detection), work-breakdown structure, priced estimate generation — "drawings in, dollars out."
Shipped a complete v2 in 2026 — rebuilt frontend and backend with a more sophisticated prediction engine, co-designed with the estimators to re-engage a disillusioned team; adoption now growing from ~15 toward 40 users across Canada.
Production ops: own the full deploy pipeline (Docker → ECR → ECS Fargate → ALB → RDS; AWS ca-central-1, WAF data-residency, IAM least-privilege) — 100% frontend availability and zero backend 5xx over the last 30 days, p95 ~200 ms; SOC 2-track posture.
Zetane Platform — enterprise document intelligence
2024—present
Source-grounded citation system — designed and built it: verifiable, paragraph-level provenance for every AI answer, with a PDF overlay that jumps to the exact cited passage across thousand-page documents. The capability that pivoted Zetane from developer tooling to enterprise document intelligence — still rare in production when it shipped (2025).
RAG pipeline: parsing, map-reduce retrieval over large corpora, grounded generation — first working version shipped in a single afternoon. Built the product's early in-chat tool-use and the chat UI (streaming, document QA, citations).
Agent execution sandbox: prototyped a Kubernetes system that runs autonomous coding agents in parallel — isolated git worktrees per agent, browser + computer-use, strict isolation for safe parallel execution.
Platform foundations & identity
2022—2025
Architected the multi-tenant SaaS foundation — front-end federation, accounts, roles, billing — that the Zetane Platform was built on. Authored the authorization stack: OIDC (Auth0, then Okta — including the production Okta integration for the flagship client) and fine-grained multi-tenant authorization.
