You will get a technical SEO audit and validated JSON-LD schema markup
Project details
You get a technical SEO audit and validated JSON-LD schema markup with a verifiable done-state — not a ranking promise. I audit crawlability, indexation, lab Core Web Vitals (Lighthouse), metadata, headings, broken links, and schema gaps, then deliver a prioritized fix list where every item gives the issue and the exact fix. I cover your tier's URLs plus site-wide items (robots.txt, sitemap, indexation), not every page.
What sets it apart: it runs against your public URLs — no CMS access needed to diagnose, and you verify the result yourself. Schema tiers add hand-written JSON-LD clearing the Schema.org Validator with 0 errors, plus a Rich Results 'valid' pass per eligible type, with PASS screenshots.
I'm new to Upwork, so my portfolio is concept / spec work, not client jobs — but it's backed by committed evidence: a Lighthouse report and a JSON-LD validator returning 0 errors across 37 typed nodes in 5 files.
Technical / structured-data work only: no content writing, keyword research, or link-building, and no ranking or traffic guarantees. Pick the tier for your scope — the price shown is the price. Rush delivery, a re-validation pass, or a walkthrough video? Message me first.

About Oscar
Data Cleaning, Web Scraping & Python | Landing Pages, AI Agents
Schiedam, Netherlands - 11:02 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.
