What I'm looking for

I seek senior engineering roles where I can lead architecture, mentor teams, build cloud-native, real-time systems, and drive measurable business impact.

I am a senior software engineer with 10+ years building large-scale, high-availability platforms across energy, commerce, and financial systems. I focus on simplifying complex operational domains and shipping reliable, scalable software that improves business outcomes.

At Enbridge I led end-to-end development of a mission-critical Liquids Scheduling Application, modernizing data flows, integrating SCADA feeds and Azure services, and reducing scheduling data latency by ~45% while achieving 99.9% uptime.

At Shopify I delivered storefront and edge platform capabilities using React, TypeScript, Hydrogen/Oxygen and microservices, improving storefront load times by ~35% and driving sub-200ms backend latencies for high-traffic features.

I mentor engineers, drive architecture decisions, and collaborate cross-functionally to translate domain complexity into intuitive engineering solutions. I seek roles where I can lead technical design, improve system reliability, and deliver measurable business impact.
