You'll start by owning a handful of sources end to end
- the scraper, the job behind it, and the data that comes out
- and take on more as you go.

Not tickets handed to you: sources you're responsible for.What you'll actually doBuild and maintain scrapers for national tender portals, where reading the source in its original language is part of the job.Keep them alive: portals change their HTML, move endpoints, break pagination, throttle you.

You find out before the customer does.Turn messy sources into clean records: broken HTML, inconsistent XML, APIs that lie about their own schema.Write and maintain orchestrator flows: retries, backfills, alerting, and a clear answer to "Did today's run actually land?"Work on merge and dedup
- the same tender arrives three times, in three shapes,



and only one version can reach the customer.Ship AI enrichment steps: batch LLM extraction of requirements, embeddings, OCR on attachments.Guard data quality with tests and checks that fail loudly before a customer finds the gap.Adecuado profilePython that holds up: typed, tested, and readable six months later.You've scraped something real: HTTP, HTML and XML parsing, pagination, sessions, rate limits
- and you know why a scraper that worked yesterday is broken this morning.SQL you're comfortable in: joins, aggregations, window functions.

You'll read from the database every day; tuning and running it isn't your job.Builder by default: you see a manual process and your first instinct is to automate it.Comfortable with messy sources: broken HTML, inconsistent XML, PDFs that were scans of scans.You close your own loop: you check that what you shipped actually ran, before someone else has to ask.Experienc
