Software Engineer with 10+ years of experience building scalable web applications and distributed systems across industries such as security, e-commerce, logistics, and financial services. For the past few years I have worked with a US-based company in a fully remote environment, collaborating with international teams to deliver high-impact software. My core expertise includes: • Backend development and distributed systems • API design and system integrations • Authentication and authorization flows (OAuth, JWT, identity providers) • Cloud-native architectures and microservices • Observability and monitoring of production systems I have experience designing and integrating secure authentication flows using platforms like Auth0, as well as building reliable integrations with third-party APIs and external services. Main technologies: Python, Node.js, AWS, Docker, and both relational and NoSQL databases. I enjoy solving complex engineering problems, designing reliable architectures, and building scalable systems.
Worked remotely with international teams to design, build, and evolve backend systems for fast-paced product environments, contributing across backend architecture, integrations, authentication, and production observability. • Designed and implemented scalable backend services using Node.js and AWS, supporting core product features and contributing to the evolution of backend architecture in a fast-paced startup environment. • Built and maintained secure authentication and authorization flows using Auth0 and OAuth 2.0, enabling secure access control and integrations across multiple clients and external systems. • Established end-to-end observability practices with Datadog, implementing structured logging, monitoring, alerting, and dashboards that gave the team visibility into system health and production behavior. • Investigated and resolved production issues using application and infrastructure monitoring, contributing to improved system reliability and faster incident diagnosis. • Collaborated daily with a distributed international team across multiple time zones, working in an asynchronous environment and contributing throughout the development lifecycle, from technical discussions and implementation to deployment and production support.
Worked on the identity and access platform supporting Serasa's consumer ecosystem, responsible for authentication, authorization, session management, and consumer data flows used by millions of users across Brazil and internal applications. • Designed, developed, and maintained backend services and APIs for critical authentication, authorization, session management, and consumer data flows using Python, Go, and AWS. • Led architectural improvements to address performance and scalability bottlenecks in a Lambda-based architecture. Migrated critical parts of the consumer data flow to specialized microservices and redesigned data storage strategies to improve platform scalability and reliability. • Helped prepare and sustain the platform during high-demand events, including major Serasa Limpa Nome campaigns, where significant spikes in consumer traffic placed additional demand on authentication and consumer data services. • Designed and optimized data persistence and access strategies across relational and NoSQL databases, improving the performance and scalability of consumer data flows. • Built and maintained integrations with IVR services, fraud analysis API providers, and internal systems. • Implemented and evolved service monitoring and observability practices using Datadog and AWS monitoring tools, supporting faster incident detection and troubleshooting.
