Arthur Dohnert
About this gig
I'm Arthur computer engineering student at UFRGS (Brazil), data science research volunteer. I write clean Python that gets your task done.
WHAT I BUILD
- Web scraping (BeautifulSoup, requests, Playwright)
- Automation (batch file work, PDF/Excel wrangling, cron scripts)
- Data processing (CSV cleanup, dedup, merges, API pulls)
HOW I WORK
1. You describe the task (URL, expected output, edge cases).
2. I confirm scope before touching code no scope creep surprises.
3. You get a self-contained script + README + sample input/output.
WHY MY CODE HOLDS UP
- Handles bad rows, network errors, empty files
- Type hints where useful
- README a non-dev can follow
STACK
Python, Pandas, NumPy, BeautifulSoup, Playwright, SQL.
Message me before ordering with your task details I'll confirm feasibility and pick the right package.

Computer Engineering student at UFRGS with experience in Python, data analysis, machine learning, and scientific computing. I currently contribute to a research project focused on scientific visualization and high-dimensional data analysis, using tools such as Pandas, NumPy, Scikit-learn, and Matplotlib. I can help with Python automation, data processing, visualization, SQL tasks, and technical documentation. I value clear communication, reliability, and delivering high-quality results on time.

FAQ
Do I need to explain everything in technical detail?
No, describe your task in plain English. If I need clarification I'll ask before starting.
What if the site I want scraped uses JavaScript / login?
Doable with Playwright, message me first with the URL and I'll confirm feasibility.
Will the script keep working over time?
For scrapers, sites can change their HTML. I include comments so you (or another dev) can update easily.
Do you handle the hosting/scheduling?
The deliverable is the script + README. Hosting is a separate discussion (usually the client's existing server or a cheap cron service).
