At one of Brazil’s largest sports retail companies, I lead backend initiatives within the Growth team to enhance user experience and boost organic traffic. I design and implement scalable microservices using Kafka, feature flags, and observability tools, contributing directly to conversion growth and search performance improvements. Highlights include: - End-to-end development of a new asynchronous filter consumer using Kafka and feature flags, replacing a legacy system — resulting in a 49% increase in sessions followed by a purchase. - Built seasonal page management systems, contributing to a 35% increase in residual traffic and a conversion rate jump from 2.59% to 4.36%. - Created quickfilters that led to a 2.11% increase in site-wide conversion. - Improved product data delivery for search pages, leading to a 10.14% session boost and a 0.25% increase in organic revenue share. Tech stack & practices: Languages: TypeScript & Golang Architecture: Event-driven (Kafka), microservices Databases: MongoDB, Redis, PostgreSQL Observability: Datadog, Grafana, Pulumi CI/CD: GitHub Actions, Kubernetes, ArgoCD Scalability: gRPC, HPA with KEDA Reliability: Feature flags for real-time rollback and deployment control Dev culture: Strong emphasis on testing, traceability, and secure delivery
