Gabriel Sanders
Data Engineer @ BYD Brasil
About
I am a dual US/Brazil citizen and I bring 3+ years of experience operating at the intersection of Data Engineering, Data Analytics, and Process Automation. My focus is on circulating across these three pillars using Python and SQL: from structuring robust ETL pipelines and generating business insights to automating manual workflows. I am passionate about leveraging AI and libraries like Pandas and Playwright to eliminate friction, ensuring data is scalable and instantly accessible to decision-makers. Tech Stack: Python (Pandas, Plotly, Streamlit, Playwright, FastAPI) | SQL | RPA | APIs | Databases | English (Native/Bilingual)

Experience

Data Engineer
BYD Brasil
Campinas, São Paulo, Brazil
- Led the implementation of an AI-powered invoice-review automation, cutting manual effort, preventing revenue leakage, and clearing a backlog that would have caused major payment delays. - Developed an end-to-end data platform, combining Apache Airflow orchestration with a custom-built UI to centralize distributed warehouse/carriers data into a structured database, providing field teams with a unified and intuitive hub for rapid decision-making. - Engineered automated reporting systems with multi-channel delivery (WhatsApp and Email), enhancing communication efficiency and providing stakeholders with seamless access to critical insights. - Utilized AI-augmented development (Cursor) to accelerate the delivery of interactive monitoring tools within a proprietary internal application, using JavaScript to visualize complex data pipelines and operational metrics in real-time.

Intern – IT Systems for After-Sales Operations
Campinas, SP
- Built an automated data pipeline using Python, Pandas, and Excel to clean, unify, aggregate, and upload more than a thousand repair orders from about 100 different dealers on a weekly basis. - Developed data-driven insights using Power BI, Pandas, Matplotlib, and Excel in the form of BI dashboards and graphs, based on collaboration with eight different departments and an understanding of their needs. - Communicate primarily in English, enhancing professional and technical discussions.

Administrative Director of Autonomous Systems
- Led the administration and coordination of the autonomous systems division, overseeing the development of an autonomous system for a student-built formula car. - Managed interdepartmental communication and supported a multidisciplinary team, ensuring seamless collaboration across the mechanical, electrical, and computer engineering departments. - Managed relationships with external stakeholders, including companies and sponsors, ensuring alignment with organizational goals and securing necessary resources. - Together with the Techincal Directior, guided the development of the autonomous systems, identifying improvements and driving innovation throughout the process.

Camera Processing Member
Campinas, São Paulo, Brasil
Computer vision applications, leveraging advanced object detection and localization techniques. - Utilized YOLO (You Only Look Once) for real-time object detection, ensuring high accuracy and speed in identifying objects within a scene. - Combined YOLO with depth mapping techniques to accurately determine the spatial position of objects relative to the camera, enabling precise 3D positioning. Applied this integrated approach in an autonomous student formula car system.

LIDAR Processing Member
Campinas, São Paulo, Brazil
Utilized LIDAR (Light Detection and Ranging) sensor technology to capture and analyze spatial data for various applications. - Implemented RANSAC (Random Sample Consensing Techniquesus) for noise filtering and outlier detection, enhancing the precision of spatial data. - Applied DBSCAN (Density-Based Spatial Clustering of Applications with Noise) for effective clustering and pattern recognition, enabling better insights in complex datasets. Contributed to projects in mapping and autonomous navigation, using optimized LIDAR data to improve performance and reliability in real-world applications.
