    Experienced Data Engineer on Upwork I specialize in data analysis (Pandas, NumPy, Matplotlib, SQL), data scraping (web pages, PDF, JSON), ETL pipeline creation, API development, and data lakes on Azure and AWS. Data Analysis Expertise: With extensive experience in data analysis using Pandas, NumPy, Matplotlib, and SQL, I possess expert-level skills in Pandas that enable me to help clients analyze existing data in CSV, Excel, and JSON formats, or from relational databases. I excel at uncovering hidden insights and visualizing results in an easily understandable way. Data Scraping and ETL Proficiency: I have extensive experience in data scraping and ETL (Extraction, Transformation, Loading) processes. I employ various techniques and tools to automate tedious daily tasks and extract valuable data from web pages, XML, PDFs, JSON objects, or API endpoints (e.g., GitHub, Slack). I can integrate the scraped data into user-friendly formats such as CSV, Excel, or relational databases. Data Lake and Cloud Tools Experience: I have experience working with data lakes on both Azure and AWS, using tools like Azure Synapse, Azure Data Lake Storage, Azure Data Factory (ADF), Amazon S3, Amazon Lake Formation, and AWS Glue to enable efficient data storage, management, and analysis at scale. API Development Skills: I am experienced in API development using Python frameworks like Flask and FastAPI, as well as DevOps-related tools such as Docker and Kubernetes (K8S). I can provide end-to-end services from development to deployment. Proficiency in Jupyter Notebook and PyScript: When a stand-alone desktop application is needed, my experience with Jupyter Notebook and PyScript enables me to create applications quickly and efficiently. Why Choose Me Over Other Freelancers: 1. Client First: I always prioritize my clients and deliver exceptional value. 2. High Quality at a Lower Price: I provide high-quality deliverables at competitive rates. 3. Friendliness: My goal is 100% client satisfaction. I strive to build long-term relationships and make friends with every client. The below Client Review is one of the many reviews provided by my client, which demonstrates the high quality of work I have delivered and the skill level I have. You can always expect the same when you work with me. "Lei is a very professional Freelancer. I love people who show initiative like him. The work is outstandingly fast delivered and the same as if code revisions are needed. While Lei's work was 100% according to our specification we faced a few issues with the code internally which was not considered before giving him instructions and test data. Although our fault he fixed the code in a blaze. He also charges very honestly the time it actually takes to code. A big thumbs up!"
