Built Loblaw Digital's first shared observability layer.

A cross-platform OpenTelemetry SDK architected as the first shared observability infrastructure across Loblaw Digital, adopted by multiple lines of business spanning divergent Next.js versions and both server and browser runtimes. Custom transformation pipelines feed VictoriaMetrics, Tempo, and Grafana, while a Zustand state store enriches distributed traces with context as they cross the server-to-client boundary.

Grafana Dashboard Proof of Concept

Defined the SDK architecture, data flow, and Grafana proof of concept that made the observability program concrete for Loblaw Digital leaders. The dashboard turns raw OpenTelemetry output into operational signals such as memory pressure, request throughput, signups, and client-side load percentiles, giving multiple lines of business a shared language for performance.

Loblaw Perfect Experience — Distributed Traces

Distributed Trace Diagnostics

Built the trace-enrichment layer that carries useful state across server rendering, browser work, and BFF calls in divergent Next.js applications. The trace view is the evidence: nested operations, service boundaries, span timing, and error points become visible without forcing every line of business to reinvent instrumentation.

Storefront Instrumentation at Scale

Shaped the SDK around real commerce surfaces instead of a clean-room demo: divergent Next.js versions, browser and server runtimes, and line-of-business requirements all had to fit one instrumentation model. The Shoppers storefront anchors the story because it proves the abstraction on a production-scale experience with frontend performance, traces, errors, and SLO signals flowing into VictoriaMetrics, Tempo, and Grafana.
