Found on 12 September 2026 by searching the open web for the account handles this site already holds for this operator, and read directly from the page cited. A portfolio site the operator publishes under its own GitHub Pages account, presenting as WILLIAM HARRIS with "10 years of experience of software development and technical writing" and a skills wall running from Solidity to TensorFlow. Its contact block is the useful part, because it gathers in one place identifiers this site held separately and adds two it did not: the address williamharris0214@gmail.com, a second Skype identifier live:.cid.456097f8358a684a, a WhatsApp link and a tel: link both to +1 646 480 0703, a Telegram link to t.me/silvani777, a Discord invite discord.gg/jRrTSsND, a StackOverflow account at stackoverflow.com/users/20988762/william-harris, and — under a page headed William Harris — a LinkedIn link to linkedin.com/in/santiagourregobotero/. The site naming one identity while linking another’s LinkedIn is the page’s own doing, not an inference drawn here. The Discord invite and the StackOverflow account are recorded in this note rather than as indicators of their own: neither has a type in this index, and an invite code is a door rather than an identifier. The second portfolio, portfolio-santiagourregobotero.vercel.app, was read the same day and is the same site with a different person in it. Identical template, identical skills wall down to a duplicated entry for Dart, and a contact block built the same way — but headed SANTIAGO URREGO BOTERO, claiming "over seven years of commercial experience" against the other page’s ten, and a National University of Singapore degree dated 2014 to 2018 against the same university dated 2009 to 2014. What ties the two pages is not the template but the contact details they share: the same Telegram account, t.me/silvani777, and the same Discord invite, discord.gg/jRrTSsND. Each page also carries its own StackOverflow account, its own Gmail address, its own GitHub, and its own Skype identifier, which this site reads as one operator maintaining two complete CVs rather than one identity drifting; that is an inference drawn here, and nothing on either page states it. It also settles a loose end. The telephone number this index holds as +1753362648 is nine subscriber digits where a North American number needs ten, and it was transcribed from a researcher’s chart; this page publishes it twice itself, as tel:+1753362648 and as wa.me/1753362648, so the malformed number is the operator’s own and not a transcription error.
