Websites, web apps, Telegram bots and n8n automations, with support after launch

Web development: business websites and landing pages in HTML, CSS, JavaScript, React and Next.js; fixes on existing WordPress and Shopify sites (broken forms, mobile layout, page speed). Web apps and internal tools with TypeScript and Node.js that replace shared spreadsheets: order boards, price calculators, CRM-style request lists. Telegram bots (Telegram Bot API) that take orders and requests and write them to Google Sheets. Automation: n8n, Make and Zapier workflows, including repair of broken ones, with alerts when something fails. AI assistants that answer only from your own documents and show the source (OpenAI and Claude APIs). Also: 3D product pages with three.js, a React Native / Expo mobile app, browser promo games, pitch decks, ad banners and brand identity.
