Education

MSc Computer Science (AI & Data Science), York University

I started as an RF engineer at Rogers, planning radios and DAS for buildings most people never look up at. Six years later I'm a Product Manager owning Rogers' Canada-wide in-building portfolio, roughly $35M a year, with a zero-rollover constraint and steering committees that don't take "trust me" for an answer.

Along the way I built a five-layer prioritization matrix to defend the line items, led the cross-carrier MOCN integration that delivered TTC 5G ahead of a federal deadline (and won the Ted Rogers Award for Innovation in 5G, 2024), and ran the first under-seat DOT deployment in Canada for Taylor Swift's Eras Tour at Rogers Centre and BC Place. The Toronto night set a single-event data record on Rogers' network: 7.4 TB.

On the "no PM on paper" question

I get it. I don't have a decade of Senior PM titles. What I do have: a current PM role with measurable scope, one production AI system I designed and shipped end-to-end (with user interviews, success metrics, A/B testing, and two security audits), and three side products that exist in the wild, including one with 30K monthly active users and a paid tier. If the bar is "would I build this here from day one," the work answers yes.

Outside Rogers I built the Telecom Standards Assistant (3GPP RAG) (37 specs, 43,121 chunks, 100% context precision, deployed publicly after two security hardening rounds), Insights Stocks (9 quant models with Benjamini-Hochberg FDR control and a Granger causality gate, pushing trade signals to Slack), and Football Intelligently (a GATv2 graph neural network on StatsBomb 360 freeze frames that hits 95.7% of StatsBomb's proprietary xG performance using only open data).

I have an MSc in Computer Science from York (AI & Data Science, full-ride scholarship), two peer-reviewed publications, and a Substack where I write bi-weekly about building AI products in the real world. Before Rogers I was a cyber-security analyst at EY in EMEIA, managing CyberArk and QRadar across 1,500 servers.
