⚙️ Data Engineering & API Automation

I build end-to-end data pipelines for agencies and scaling businesses. I specialize in bypassing modern bot-protection to extract clean data, and piping it directly into the operational tools your team already uses.


🛠️ Core Tech Stack



📌 Production Pipelines

Below are three of my core architectural blueprints. Click into any repository to see the complete ETL flow, Mermaid architecture diagrams, and clean code standards.


Stack: Python | BeautifulSoup | JSON Parsing

  • Headless Extraction: Bypasses visual rendering to directly parse hidden JSON dictionaries.
  • Automated Data Cleaning: Normalizes raw string data and calculates dynamic discount percentages.

Stack: Playwright | Pandas | Proxy Rotation

  • Human Mimicry: Configured browser contexts with realistic viewports and randomized delays.
  • DOM Navigation: Programmatically handles JavaScript pagination and lazy-loaded elements.

Stack: gspread | Google Auth | REST APIs

  • Authentication: Secure OAuth 2.0 validation via GCP Service Accounts.
  • Auto-Formatting: Programmatically freezes headers, bolds text, and adjusts column widths post-injection.
