Principal Data Platform Architect. Contract-backed Gold. Nothing leaves without a contract.
I founded Ambient Systems. I will not let a Gold product leave the boundary without a contract. Patent WO/2022/240365. NUS MComp, U of T Engineering.
About
I build a governed lakehouse on Databricks and Unity Catalog. Gold leaves only through governed adapters. Ambient Core is MIT open core. Inventor on WIPO WO/2022/240365.
I founded Ambient Systems (Hong Kong HQ). Commercial activity is paused. Based in Toronto and Hong Kong. ambientsystems.ai
The through-line from Deloitte through Centennial is in Work below.
Work
For thirteen years the through-line was controls, cost, and audit evidence. Today I run the same discipline on a governed lakehouse: contract-backed Gold at Ambient Systems, with Ambient Core (MIT) for an inspectable boundary.
Through-line (2013–2024)
| Situation | Role | What I did | What changed |
|---|---|---|---|
| Deloitte Nineteen engagements across financial services and energy; one mining client needed energy cost down. | Analyst — controls and analytics tied to operating numbers. | CAATs-backed controls testing; energy models on operational data under consulting delivery constraints. | Roughly 12 percent lower energy cost on the mining engagement. |
| SunFarmer A $2M procurement with operating cost at stake. | Senior product manager — own the buy and the data path. | Ran procurement at SunFarmer / SEED Energy; data products and automation on commercial and ops levers. | Procurement and ops cost cut where measured (~40 percent vs market / ops baseline). |
| Rotman A $25M incubator (2,000+ organizations) with audit expectations on program data. | Technology project manager — program-scale governance. | Structured data flows, reporting, and controls so stewardship and lineage stayed visible to operators and reviewers. | Audit-ready portfolio reporting at program scale. |
| Centennial Regulated post-secondary cohorts (~25 students) in AI, cloud, and data. | Sessional professor and principal investigator. | Curricula in AI/ML, cloud, and analytics; industry R&D pipelines and CNN models as PI. | Teaching and R&D with lineage and control in view each cohort. |
Ambient (now)
| Situation | Role | What I did | What changed |
|---|---|---|---|
| Ambient Systems BI, sharing, and compliance need numbers that survive review. | Founder and principal architect — contract-backed Gold; nothing leaves without a contract. | Multi-tenant medallion lakehouse on Databricks and Unity Catalog; Gold only through governed adapters and data product contracts (schemas, SLAs, quality, lineage). | Reusable Gold for Power BI, Tableau, and Delta Sharing; correctness lives in the contract. |
| Ambient Core Intelligence paths that bypass the catalog are hard to audit later. | Open-core patterns — MIT catalog and contract boundary. | Published governed data-product and routing patterns so the boundary is inspectable outside one private stack. | Intelligence consumes through catalog products — same rule in open core and production. |
