A service that watches a website so its owner doesn’t have to: uptime checks every minute from three regions, SSL and DNS control, vulnerability scanning, and Lighthouse performance audits. Under the hood — four services: a Laravel dashboard, Python uptime monitor and security scanner, and a Node.js performance service.

A commercial service built from scratch, running since 2022: servers in six countries, VLESS, Shadowsocks, and Trojan protocols, up to three devices per key. A Telegram bot is the single interface — purchases, renewals, key delivery, and support all happen there.

An EdTech startup: an English speaking trainer where the AI holds a voice conversation, remembers past sessions, and builds every next one on the last. Includes a full 12-minute IELTS Speaking mock test, role-play scenarios, and pronunciation feedback after every session.

An open source scanner written in Go: hunts for web shells, backdoors, phishing, and infected files. 3,300+ signatures, 7 specialized detectors, recursive deobfuscation, and AI-powered triage via Claude. Multi-threaded — thousands of files in seconds.
