As a seasoned data analyst with a Bachelor's degree in Applied Statistics With IT, I have a robust understanding of the precise data analysis and modeling your project requires. My strongest suit in this venture is my proficiency in Python; something that will be pivotal in addressing the task at hand through AWS Sagemaker. Supplementing this skill set are my knowledge and experience in NLP, statistical modeling, and text analysis with R programming.
Another complementary aspect I bring to the table is my understanding of web development including HTML/CSS/JavaScript. This facility will enable me to create a code structure on your AWS account that performs seamlessly online without requiring exhausting local processing power, all while retaining accessibility from any local computer. Working autonomously, I'll equip your project with functionalities such as auto-scaling for as many instances as stipulated by the document processing requests. I'll also design a flexible interface allowing any user to raise dynamically defined queries for custom document processing.
