What I'm looking for

I’m looking for a role where I can build scalable backend systems—microservices, REST APIs, and serverless on AWS—own reliable payment integrations, and improve observability and performance in an Agile environment that values Clean Code and SOLID.

I’m a Senior Software Engineer with over 8 years of experience designing and building scalable backend systems. I specialize in PHP (Laravel), Python, Node.js, and AWS, delivering reliable, secure services for EdTech, e-commerce, and sports event platforms.

At Gran Cursos Online, I designed and developed microservices and REST APIs, built AWS Lambda functions for asynchronous and serverless workloads, and improved performance through large-scale data processing, query optimization, caching strategies, and asynchronous queues. I also helped deliver AI-powered features, including automated question explanations and personalized learning capabilities.

I’m equally focused on integrations and operational excellence—especially payment workflows. I’ve implemented full payment lifecycles with PIX and credit cards (webhooks, reconciliation, refunds, and idempotency), and I’ve worked on observability and troubleshooting to continuously optimize platform reliability while maintaining Clean Code and SOLID practices.
