You will get a clean, structured dataset — Python ETL from your raw data
Project details
You will get a clean, structured dataset ready for analysis, reporting, or import — delivered as CSV or Excel with a summary of every change made.
I have 15+ years of experience working with messy real-world data across business operations, call centers, and financial tracking. I use Python (pandas) to handle duplicates, inconsistent formatting, missing values, type mismatches, and custom transformations — whatever your data needs.
Every delivery includes a changelog so you know exactly what was fixed and why. No black-box cleaning — you get full visibility into the process.

About John
Python & SQL Automation Specialist | Data Cleaning, ETL & Scripting
Watertown, United States - 3:31 pm local time
With 15+ years of hands-on experience across data analysis, automation, and operations, I've built dashboards, written ETL pipelines, cleaned messy datasets, automated repetitive workflows, and connected APIs to make systems talk to each other. I've worked across call center analytics, lab operations, e-commerce, and workforce intelligence — so I adapt quickly to new domains.
What I typically help with:
- Python scripting for data cleaning, transformation, and automation
- SQL queries, database maintenance, and report generation
- ETL pipelines and data wrangling from raw sources
- Power BI / Tableau / Google Sheets dashboards
- Workflow automation (Python bots, CRON jobs, API integrations)
- Excel automation and reporting (including VBA/scripting)
I've been building things independently under Wanatux since 2008 — client work, web tools, bots, scrapers, and integrations. I know how to scope a problem, deliver something that works, and communicate clearly without overcomplicating it.
If you have a defined task and need someone who can execute reliably without handholding, let's talk.
