Hi there! 👋🏻

I am Rui, based in Greater Phoenix, Arizona. With over a decade of experience, I specialize in crafting seamless web interfaces, robust server-side databases, and efficient APIs for diverse web and mobile applications. My expertise spans Full Stack Development, AI, Amazon Web Services (AWS), and Infrastructure as Code (IaC), enabling me to deliver scalable and high-performance web solutions.

I am committed to using cutting-edge technologies to enhance user experiences, drive data-driven decision making, and foster business growth. Passionate about continuous learning, I keep myself at the forefront of web development trends and best practices.

On the AI front, I have hands-on experience integrating large language models and advanced analytics into production environments. I leverage OpenAI solutions and other LLM services to build intelligent applications utilizing retrieval-augmented generation (RAG) pipelines. I incorporate RAGAs to measure model accuracy, relevance, and performance, ensuring robust AI-driven functionalities at scale.

I enjoy building applications using modern frontend frameworks like Next.js, and backend frameworks like Spring, ASP.NET, and FastAPI. I build RESTful and GraphQL-based applications alongside CI/CD tools and perform integration, unit, functional, and acceptance testing.

I have experience working on projects of various scales, from small web applications to enterprise-level distributed microservices. I am proficient in Agile/Scrum methodologies and have worked with development/deployment tools including Git, Kubernetes, Terraform, Docker, and OpenShift.

I am a passionate problem solver who thrives in team environments and is eager to align technology with business goals for transformative outcomes.
