I’m a Full-Stack Software Engineer with 5+ years building IoT platforms and full-stack systems using TypeScript/Node.js, React.js, and cloud infrastructure across AWS, GCP, and Kubernetes. I bring end-to-end ownership, blending polyglot persistence with reactive, production-grade frontend development to deliver scalable solutions.

Most recently, I architected and led a highly available, event-driven IoT platform that reduced cloud infrastructure costs by 70% while supporting 30,000+ connected devices. I engineered a resilient microservices ecosystem (Apache Pulsar, gRPC, Redis, DynamoDB, Elasticsearch, S3, EKS) to process telemetry streams up to 7,000 messages/sec at peak, and I designed a high-performance B2B2C React front-end for real-time operational control. I also engineered an end-to-end full-stack platform (Next.js, MongoDB, WebSerial API) that successfully configured and validated 200,000+ IoT devices, reducing data-enrichment latency by 90% (72ms to 7ms) with Protobuf, parallel I/O, and advanced Redis techniques.

Earlier work includes building full-stack billing and messaging capabilities with Banco do Brasil PIX API integrations, scaling real-time command delivery to 25,000+ SIMCards, and migrating a legacy monolith to microservices using DDD and Clean Architecture with Kubernetes-based CI/CD. I’m also comfortable strengthening engineering practices—testing with Cypress, improving developer experience, and mentoring—so teams ship reliable software faster.
