01. About Me

The story so far

Full-stack engineer with 15+ years across development, product ownership, and business/systems analysis, owning ambiguous, customer-facing technical work end-to-end. I scope and deliver integrations against real business systems (ERP, POS, reporting), build production APIs and data pipelines, and turn customer requirements directly into shipped features.

Based in the Greater Toronto Area, I bring a unique blend of technical depth and product thinking to every project. My background spans full-stack development, Agile product ownership, systems analysis, and cybersecurity.

Most recently a Software Engineer at Corpay, shipping backend and UI changes on a production payments platform. Alongside that, I've been integrating LLM agents and AI product features into live applications — most recently Pronto, an AI-powered ride and delivery platform for the GTA.
