Define and own the long-term architectural evolution of a globally distributed control-plane platform serving 450M+ consumers and 36M+ merchants, operating at ~150K+ requests/sec with 99.99% availability across multi-region deployments.
Leading a multi-year cloud modernization initiative decomposing a legacy monolithic system into independently scalable, low-latency services, introducing cell-based regional isolation and distributed decisioning; initial ramp supports ~25% of high-throughput API traffic with sub-10ms decision targets.
Driving platform-wide performance optimization across critical request paths, setting technical direction and guiding teams on latency reduction, capacity efficiency, and SLO-safe rollout strategies.
Architected platform extensions enabling high-volume checkout and passwordless access flows while preserving latency and resiliency guarantees under global traffic conditions.
Designed cross-platform interoperability mechanisms supporting large-scale user convergence (70M+ users) with production rollout in under four weeks.
Contribute to platform-wide architectural governance through formal design reviews, ADR standards, technical hiring, and mentorship of senior engineers, strengthening distributed systems rigor across service domains.
