What I write about: Etsy fees, scraping, Telegram bots

By trade I build parsers, Telegram bots, dashboards, and calculators, and this blog holds the working notes: what Etsy actually withholds from a sale, what a parser may collect from Amazon without crossing the rules, what breaks when a bot moves from Telegram to MAX. Most pieces come out of client work or my own tools, and each one carries numbers or a working artifact rather than a summary of other people’s posts. Below are the ten pages search engines show most often, as of October 2026, with one line each on why you might open it.

What to read first

1. Etsy Fees in 2026: How Much the Platform Takes. All six fee lines on a sale, counted on a worked $30 order. The page search shows most often.
2. Etsy Tariffs in 2026: What Sellers and Buyers Pay. Since July 9, US orders ship DDP and the tariff is baked into the item price; what that does to margin, with the math.
3. Etsy Tariff Calculator. The live version of that math: every 2026 fee line, tariff included, counted in the browser. Nothing to install.
4. How to make product cards for Wildberries and Ozon. Cover photo, infographic, title, specs: the whole card, step by step.
5. Etsy Fee Calculator: How to Compute Your Real 2026 Profit. Why most calculators undercount: the lines they skip, and how to count all six by hand.
6. Migrating a Telegram bot to MAX in 2026: what changes. Logic and CRM hooks move over whole; only the Bot API layer and payments get rebuilt. The code takes days.
7. DDP Calculator. The tariff half of the Etsy math: the DDP charge on a US order, the duty and who pays what.
8. Is Web Scraping Legal in 2026? Rules by Method and Data Type. Not a yes or no: three documents, the law, the site’s terms, and its robots.txt, decide it per method and per data type.
9. Amazon Scraping: What the Rules Actually Allow. Amazon leaves product pages open to crawlers while its terms ban data mining tools; what each rule actually covers.
10. Etsy Fee Calculator Extension for Chrome. The same fee breakdown living under the price of any open listing; one permission, zero network calls.

The standing invitation

Most of these pages started the same way: someone had a task. Price a shop against the 2026 fees. Watch a competitor’s prices without checking the site by hand. Catch the calls a one-person business keeps missing. Move a bot to a new platform before the deadline. If that is where you are, write to me and tell me about it. The first conversation costs nothing, and it usually ends one of two ways: a concrete plan, or an honest “you don’t need me for this”. Both are fine outcomes.
