🤓 facts about me:

• passionate about technologies that change people's lives
• coding since 15 years old
• 11+ years of programming, 6+ with python, 6+ in data.
• my main interests are in open-source, self-service data platforms, MLOps, DDD, and TDD

💼 I have many years of experience building data platforms and dev tools in modern tech organizations. From small startups (< 50) to 10k+ corporations I know how to operate in different growth stages.

📚 I've studied at the Federal University of São Paulo (UNIFESP). I have a bachelor's degree in Science and Technology and another in Computer Science. I have also recently finished a master of science in intelligent systems, with my research in the last 4 years focused on automated anomaly detection for data quality exploring novel architectures of AutoML and Metrics Repository. My university is one of the most prestigious in Brazil, fully funded by the Brazilian government. In the years I was there it was elected top 5 in all LATAM by Time Higher Education.

If you're passionate about data quality like me, you'll definitely like my publication which can be read here.

• biar: batteries-included async requests tool for python
• thoth: Python tool for profiling-based anomaly monitoring on ETL data pipelines leveraging ML and Apache Spark.

I'm also the co-creator of butterfree a tool for feature engineering and feature store. We created this tool when I was in the first MLOps squad at @quintoandar. It's used for most ML data pipelines there and has 260+ stars on GitHub.

I've also made minor contributions for the following awesome open-source libraries:

• aws-sdk-pandas: easy data integration with AWS services.
• merlion: a time series forecasting library for python.

I have a bunch of data engineer test cases which landed me Senior positions in competitive tech companies. So before asking me a take-home assignment, please check these instead:

• strider-challenge: a simple typer and sqlmodel application developed with DDD and TDD
• pyspark-pipeline: shows the implementation of a pyspark data aggregation pipeline with automated tests.
• legiti-challenge: A nice project solution for building and running pipelines for feature store.
• meli-challenge: a solution for the characters interactions problem using graph and spark.

Here's an archive of old college projects (don't judge me 😅):

• ntsa: repository for codes, reports, and projects for the Nonlinear Time Series Analysis class from Computer Science Master's Degree Course at Federal University of São Paulo (UNIFESP).
• neural-networs: repository for the projects of the 2019 Neural Networks class at National Institute for Space Research (INPE)
• software-testing: Repository for the projects of the 2020 Software Testing class at the Federal University of São Paulo (UNIFESP)
