Turkish E-Commerce Arbitrage Tool

I want a custom application that mimics the core strengths of Tactical Arbitrage but focuses on the Turkish market. The tool must scrape or fetch data from toptantr.com, toptanservis.com.tr and trendyol.com, then compare identical or highly similar SKUs to reveal profitable opportunities.

Key capabilities I need baked in:
• Accurate product-to-product price comparison across the three sites
• Automatic profit margin calculations that factor in fees, shipping or any other costs I can define through a settings panel
• A simple sales-trend module so I can see how each item has moved over the past weeks or months and spot consistent winners

I’m happy with a cron job, Windows Task Scheduler or any lightweight scheduler you prefer, as long as the update cadence is reliable and I can trigger a manual refresh when needed.

Preferred stack is flexible—Python with BeautifulSoup/Scrapy, Node with Puppeteer or any robust combination you’re comfortable maintaining. What matters is clean, well-annotated code, clear setup instructions and resilience to minor site layout changes.

Deliverables I expect:
– Executable (desktop or headless script) plus source code
– Modules that pull data from each of the three marketplaces, map SKUs and output a consolidated view with price, calculated profit and recent sales trend graph or table
– CSV or Google Sheets export and an on-screen dashboard or CLI summary
– Read-me covering installation, config of credentials/cookies, how to edit cost variables and how to adjust the weekly scheduler

I’ll test the build on my own machine: if it completes a full cycle, matches at least 95 % of visible prices and produces the margin report without errors, I’ll sign off. Let me know your preferred libraries and estimated timeline so we can get started.
