Review designs and pull requests for Commerce, services, and storefront layers, resolving complex cross-layer defects at their root cause
Advise on capacity planning, caching strategies, search, and failure modes for a high-traffic B2B storefront
Mentor senior engineers and leads, documenting architecture decisions with context, options, and consequences to ensure continuity
