Lucca Hiratsuca Costa

I’m a Senior Data Scientist and Software Engineer specialized in Artificial Intelligence, Machine Learning, and Software Engineering. I’ve built production-scale AI systems across Accenture, Vivo, JBS, and Rede D’Or, with a focus on turning data and models into reliable, real-world products.

In my current role at Rede D’Or, I develop data pipelines and transformations with Python, PySpark, and SQL across lake layers for analytical consumption. I also build generative AI solutions integrating Brazil LLMs via APIs and AWS Bedrock, and I create APIs and serverless services with AWS Lambda and API Gateway.

I bring strong backend engineering foundations—microservices in Python and Java, scalable architectures using DDD and Hexagonal patterns, and orchestration approaches for agentic workflows. At Accenture and Vivo, I delivered production services, using Spring Boot and FastAPI, plus asynchronous communication with Apache Kafka and CI/CD practices in Azure DevOps with Git.

I’m equally comfortable with data and MLOps: working with MongoDB, observability using CloudWatch, retrieval-augmented generation with LangChain and LLMs, and ML lifecycle tooling like MLflow. From building RAG systems and using embeddings/LLMs to forecasting demand with Prophet/ARIMA/SARIMA, and automating workflows through web scraping, I aim to bridge AI and engineering to deliver impactful, scalable outcomes.
