About this Gig

Stop struggling with messy data. Lets build automated systems that work for you!

Are you dealing with unorganized databases, broken data pipelines, or manual Excel tasks that waste your valuable time? I am a professional data engineer here to clean, process, and automate your data workflows.

I specialize in turning raw, unstructured data into clean, structured datasets and automated ETL (Extract, Transform, Load) pipelines. Whether you need Python automation, database optimization, or reliable web scraping, I deliver production-ready code.

️Core Services I Offer:

  • ETL Pipeline Development: Automate data collection from APIs, CSVs, or web sources straight into your database.
  • Data Cleaning & Preprocessing: Fix missing values, remove duplicates, and structure messy data using Python (Pandas/NumPy).
  • Database Design & SQL Optimization: Write efficient SQL queries, design database schemas, and fix slow-running databases.
  • Advanced Web Scraping: Extract large volumes of data from websites safely and legally into structured JSON or Excel formats.
  • Data Integration: Connect disparate data sources (e.g., Shopify, Stripe, HubSpot) to central data warehouses like BigQuery or PostgreSQL
