Work within a cross-functional Agile/Scrum team, participating in sprint planning, backlog grooming, daily stand-ups, and retrospectives to prioritize and ship gRPC migration and reliability work each sprint.
- Leading the migration of internal service-to-service communication from HTTP to gRPC, standardizing internal APIs and improving consistency, type safety, and maintainability across the delivery services domain.
- Extended retail inventory eligibility/availability checks (STH/SFS/IDL/IPK) to route by call type — merchandising, standard checkout, and high-load — across dedicated backend partitions, improving resilience against traffic spikes in a critical buy-flow dependency.
- Diagnosed and resolved a correctness-vs-performance tradeoff in a caching layer: an earlier optimization that normalized cache keys for hit-rate had silently broken eligibility for a specific cart shape. Redesigned the approach to segment normalization by uniqueness rather than reverting the optimization outright — preserving the performance win while eliminating the correctness gap, and added regression coverage to prevent recurrence.
- Owned reliability hardening of a critical checkout-path microservice, root-causing and resolving multiple production NPEs surfaced from live traffic, prioritizing fixes by customer impact.
- Drove OpenAPI contract upgrades across multiple interdependent downstream services, coordinating spec changes to avoid breaking consumers during rollout.
- Leverage Claude Code and agentic developer tooling in daily engineering workflows to accelerate feature development and code review cycles.
