You will get Clean, deduped Excel/CSV data plus a re-runnable Python script
Project details
You get the SCRIPT you can re-run, not just a one-off cleaned file. Most cheap cleans hand you a tidied
file; next month's export lands just as messy. Every tier ships the re-runnable Python script + README, so
the next file is one command — and you own it, never locked to me. Standard and Advanced are parameterized,
so you re-run it yourself.
You also get a plain-language change log, and odd values are FLAGGED, not deleted — I never destroy an
anomaly you wanted to keep.
What I don't do: analyze the data (no charts, pivots, or dashboards), collect or scrape new data, or
research values that aren't in your file. That focus keeps it fast and predictable.
Honest note: I'm new to Upwork freelancing, so I have no reviews yet — check my method instead. The
portfolio here is labelled concept / spec work: a real pandas pipeline that took 1,000 messy records to a
clean, deduped, correctly-typed file with 0 rows dropped. My background is in CRM and marketing
automation — context, not the headline.
Pick the tier that matches your rows and file count — every tier's scope is above. Unusual job (merged
cells, large files, PDFs)? Message me before ordering for the right tier and add-ons.

About Oscar
Data Cleaning, Web Scraping & Python | Landing Pages, AI Agents
Schiedam, Netherlands - 2:03 am local time
spreadsheet with the script that produced it, a landing page you can open in a browser, a
re-runnable scraper, or a documented Python tool — each with a short README and a fixed price.
First reply is usually same-day, often with two or three questions that tighten the scope before
you spend a cent.
I take jobs that have a clear brief and a result you can verify without taking my word for it —
files you open, a script you re-run, a page you look at. What I build, end to end:
- Data cleaning and spreadsheets — Python and pandas: deduplication, normalization, and messy
Excel/CSV turned into a tidy file plus the re-runnable script that produced it.
- Web scraping — public, non-personal data into a structured CSV, delivered as a script you can run again, not a one-off dump. ToS-aware by default.
- Python automation — small scripts and CLI tools for the repetitive job: parsing, reporting, ETL,
file processing, with tests and a README.
- Websites and landing pages — coded from your Figma or a concrete design, pixel-checked, responsive, with a Lighthouse pass. I code designs that exist, not open-ended concepts.
- Documents, email, and technical SEO — auto-generated PDFs and decks from your data, responsive HTML/MJML email templates, and SEO audits with validated schema markup and a concrete fix list.
- AI agents and RAG — chatbots and assistants that answer over your own documents, delivered as a runnable repo with a demo.
How I work:
- Fixed price, scoped to the outcome. Anything over ~EUR 400 splits into milestones, so you approve in stages and never pay ahead of delivered work.
- Fast single-pass delivery, with a round or two of revisions already built into the quote.
- Every deliverable ships with a README and a re-run or handover note, so you are never dependent on me to keep it running.
- My delivery is AI-augmented — I build with Claude Code and test everything I ship. I am glad to
explain exactly how, and I decline anything deceptive or against a platform's terms.
I am new to freelancing on Upwork: the portfolio here is labelled concept work built to demonstrate
each capability, not past client jobs. My professional background is in CRM and marketing automation (Oracle Responsys, email development, customer data) — useful context, not the headline. Send the brief and I will reply with a fixed price, a timeline, and the questions that actually matter.
Steps for completing your project
After purchasing the project, send requirements so Oscar can start the project.
Delivery time starts when Oscar receives requirements from you.
Oscar works on your project following the steps below.
Revisions may occur after the delivery date.
Scope lock
From your intake answers I confirm the dedupe key, the columns that matter (with coded-column definitions), your missing-value and anomaly rules, and what "clean" means to you — and I flag merged cells, multi-row headers, or scanned PDFs first.
Clean + normalize
I write a Python/pandas script that removes duplicates on your key, fixes data types, trims and standardizes text, normalizes formats (dates, phone, case), handles blanks by your rule, and FLAGS anomalies. Multi-file jobs are merged on your key.
