Gabriel Henrique Martins

Played a key role in VTEX's B2B/B2C commerce platform by modernizing core infrastructure and launching internal tools for product catalog management, user roles, billing, and data pipelines. Spearheaded architecture of a HIPAA-compliant healthcare extension, built microservices using Python and Node.js, and managed asynchronous transactions with Apache Kafka and RabbitMQ. Designed front-end modules with React, Next.js, and Redux Toolkit, integrating with GraphQL and CMS plugins. Developed a wellness content prototype with React Native and Redis Pub/Sub. Managed deployments with Terraform, Docker, and Kubernetes on AWS EKS, maintained observability through Grafana, Datadog, and Prometheus. Collaborated with data teams integrating BigQuery and ClickHouse for performance analytics. Contributed to security through scoped RBAC, JWT tokens, and 2FA. Ensured high-quality delivery with CI/CD, Jest, and Pytest. Mentored junior developers and led workshops on microservices, GraphQL, and cloud co
