About

Professional summary

I am a Senior Software Engineer with more than seven years of experience building AI, backend, cloud, and automation solutions. I work primarily with Python and Java to deliver scalable services, APIs, distributed systems, and production-ready applications.

I have hands-on experience with machine learning, deep learning, computer vision, natural language processing, Generative AI, large language models, and Retrieval-Augmented Generation. I enjoy rapidly prototyping AI solutions and integrating them into practical business systems.

My backend experience includes designing RESTful APIs, authentication services, third-party integrations, data pipelines, and cloud-based infrastructure. I have worked with Spring Boot, Django, FastAPI, Flask, SQL and NoSQL databases, event-driven systems, and CI/CD automation.

I have contributed to projects involving RAG chatbots, machine-learning pipelines, computer vision, identity and authorization systems, alerting platforms, and communication integrations. My work has improved prototyping speed, deployment processes, observability, operational efficiency, and application reliability.

I am comfortable collaborating in Agile teams through code reviews, sprint planning, technical troubleshooting, architecture discussions, and cross-functional system integration. I am fluent in English and Portuguese and am focused on remote software engineering opportunities involving AI, backend, cloud, and data systems.
