🚀 Hi, I'm Tyrell O Hullum 👋

Computer Science | AI & Data | Computer Vision | Data Engineering | Cloud

Welcome to my technical portfolio. I'm a Computer Science student building hands-on projects across artificial intelligence, computer vision, data engineering, cloud technologies, and analytics.

My work includes YOLO object detection, OpenCV lane detection, self-driving behavior cloning, Snowflake analytics, and Databricks data engineering pipelines.

☁️ AWS Serverless Sales Data Pipeline

Built and deployed an event-driven AWS data pipeline for synthetic e-commerce sales data.

Pipeline: Amazon S3 → AWS Lambda/Python ETL → Amazon S3 → AWS Glue Data Catalog → Amazon Athena

Highlights:

  • Automated CSV processing using an S3 event trigger
  • Python ETL for duplicate removal, data standardization, missing-value handling, and revenue calculation
  • Least-privilege IAM permissions
  • AWS Glue schema discovery and Data Catalog integration
  • Serverless SQL analytics with Amazon Athena
  • End-to-end AWS deployment documented with console screenshots

Technologies: AWS S3 • Lambda • Glue • Athena • IAM • Python • SQL
