Real projects I've built — websites, AI tools, and web apps for small businesses.
A 47,650-LOC async Python platform for MetaTrader 5 / prop-firm challenges, built around a fail-closed, seven-layer risk engine — and honest enough to prove, out-of-sample, that its own strategy has no edge yet.
A Telegram bot that manages Google Ads in plain language — but never on its own. Every budget, bid or keyword change is shown as a 'before → after' diff and runs only after you approve it. Multi-model AI, keyword research, RSA ad-copy and deep .xlsx / Google Sheets reports — a production client build with ~110k lines of Python and 2,030 automated tests behind the chat.
Full-stack migration of a marketing professional's website from Wix to a custom Next.js 15 serverless architecture on Cloudflare Workers. Mobile LCP cut from 13.2s to 0.8s — a perfect 100/100 Lighthouse.
Demo salon website with live appointment booking (Upstash Redis), Gemini AI reception chat, and full DSGVO compliance.
Demo site for a local electrician — built to get found in local search and turn visitors into quote requests, not just clicks. DSGVO-compliant.
Demo restaurant site showing direct, commission-free reservations 24/7 and a self-serve menu — so the restaurant keeps the margin delivery portals take. Bilingual (DE/EN), DSGVO-compliant.
Production full-stack portfolio: AI chatbot (Gemini), Sanity CMS, PostgreSQL + Prisma, NextAuth OAuth, CI/CD via GitHub Actions. 99/100 Lighthouse, 3 languages.
