Project history
Personalized AI agent for automated crypto Twitter/X monitoring with self-improving memory. Features dual-layer memory with SQLite DB, Underradar Detector for real-time influencer flagging, and 6-direction data pipeline via Playwright browser automation without API keys.
Production automated trading bot implementing delta-neutral funding rate arbitrage with 178 commits and ~28,600 lines of production code. Integrated 10 exchanges via unified abstract adapter using Template Method Pattern. Designed 3 execution modes and 6 close modes, real-time order book monitoring via WebSocket, EIP-712 Ethereum wallet signing, RAM-based state management with JSON persistence, and pytest async test suites.
Full-cycle commercial website for a real private clinic built with Eleventy (SSG), Sveltia CMS, GitHub Actions, Tailwind CSS, and Schema.org SEO. Implemented static site with Eleventy and Nunjucks, headless Sveltia CMS for client content editing, GitHub Actions CI/CD, and full SEO stack including Schema.org MedicalClinic, OpenGraph, sitemap.xml, and Google Search Console.
