About this Gig

Hi, Im César. I'm an engineer with 3+ years of experience building data systems and automating workflows for government and infrastructure clients.

I don't just run basic scraper tools; I write custom Python scripts to solve messy data problems. As an example, in a recent project, I wrote a script that pulled mapped contact data from over 1,000 unstructured legal PDFs in under 4 minutesa task that previously took a team 60+ manual hours.

Here is what I can build for you:

  • Custom Data Extraction: Pulling clean data from websites, even if they have logins, pagination, or dynamic JavaScript.
  • Data Cleaning & Formatting: Taking your messy CSVs, Excel files, or PDFs and using Pandas to filter, deduplicate, and format them exactly how you need them.
  • ETL Pipelines: Moving raw data from any source into clean, structured outputs (CSV, JSON, SQL).
  • Automated Scripts: I can deliver the fully documented Python source code so you can run the extraction yourself whenever you want.

Every script I deliver is modular, heavily commented, and built to handle errors without crashing.

Important: Please send me a quick message with your target URL or sample file before placing an order. I like to scope eve
