- First data hire at a bold Brazilian EdTech, I'm responsible for designing and delivering the company’s end-to-end data pipeline, from extraction to final applications. Built a system that is scalable, highly available, fault-tolerant, and cost-efficient, enabling streamlined maintenance and rapid integration of new data sources.- Developed and maintained ELT/ETL pipelines using Python, SQL, and Dagster, transforming raw data from sources like MongoDB, ERP systems, Google Analytics (GA), REST APIs, spreadsheets, and documents into business-ready datasets for analytics and reporting.- Designed data models in BigQuery and built a comprehensive analytics platform in Metabase, providing tailored internal reports and client-facing insights to support strategic decision-making.- Collaborated cross-functionally with Product, Finance, C-level, and tech teams to translate business requirements into technical solutions. Led the creation of new metrics, optimized workflows, and delivered interactive dashboards, reports, and presentations that directly supported business goals.- Implemented critical data processes such as idempotency, deduplication, and incremental extraction, ensuring data consistency and reliable decision-making across the company.- Monitored and optimized data pipelines to ensure efficient processing, troubleshoot issues, and guarantee timely data delivery.

- Undergraduate researcher at PIBIC nota 10 program, with the “Project Driven Data Science” research project I've conceived to encompass mine and future data science research among undergraduate students.- Started with an exploratory research on the definition, tools and methods of data science and machine learning.- Developed and delivered a summer course on data science fundamentals using R for Data Science book.- Built a data extraction and analysis pipeline to provide insights on university students’ subjects, enabling course coordinators to make informed decisions on resource allocation.- Researched Active Inference, a promising concept for understanding cognition, which has the potential to advance our understanding of human and artificial intelligence.- Hard Skills: Python (Pandas, NumPy, Matplotlib, Scikit‑learn, pyxpdf), SQL (SQLite), R (ggplot2, dplyr, tidyr, readr), Linux (shell, ssh, CLI, APIs),Git, GitHub, Docker, Latex, ETL, data science, data engineering.- Soft Skills: self‑management, self‑learning, critical thinking, research, technical and non‑technical communication (writing and presentations)

- At UENF, I addressed a crucial problem faced by coordinators and laboratory chiefs: the lack of a reliable way to predict student enrollment for upcoming subjects. To tackle this issue, I created an anonymized and abstracted database called "consulta_academica." This database enables easy development of data routines and features while ensuring the privacy and performance of our system.- Using Docker, Postgres, SQL scripts, and Python, I designed a seamless system to extract, transform, and load data from the Sistema Acadêmico into the consulta_academica database. This laid the groundwork for future data projects and fostered a data-driven culture within the university.- I developed a functionality that calculates students' demand for each subject, aiding coordinators in resource allocation and planning. Currently, I am working on integrating the system with the Sistema Acadêmico via RabbitMQ for automatic data updates.- This project is expected to save time and improve satisfaction among students, professors, and staff using the Sistema Acadêmico.

- Took over my parents’ small bakery, to prevent it from going bankrupt.- Managed employees, finances, inventory, purchasing, production, accounting, and marketing campaigns to maximize efficiency.- Used spreadsheets extensively to organize data and inform my decisions.- Developed Python Jupyter Notebooks to extract and visualize sales data and create rudimentary predictive models to aid in bread production planning and purchasing goods.- Maintained high academic performance despite the demands and challenges of running a business.- Successfully kept the bakery afloat, renovated the establishment, recovered the customer base, and became a local reference.- The bakery is still in operation today, now leased to new owners that continue the work we began.- Hard Skills: management (project, production, inventory, financial), marketing, Sales, Purchasing, business communication, spreadsheets, Python (Jupyter Notebook, Pandas).- Soft Skills: leadership, accountability, work ethic, commitment, decision‑Making, team management, communication, conflict resolution, perseverance and adaptability.

In my first professional role, I supported daily operations by managing documents, spreadsheets, coordinating tasks, and running errands. Despite the routine nature of the work, the relationships I built and the skills I developed had a lasting impact on my growth. This experience taught me the importance of contributing meaningfully to both colleagues and customers through process improvements, active listening, and driving efficiency.I gained valuable insights into office administration and enhanced my ability to identify solutions, improve workflows, and understand the broader needs of the business. This role fostered a passion for helping others and established a strong foundation for my professional journey.
