→Selected Projects
WooCommerce → GLS Shipping Automation No API
GLS Croatia has no WooCommerce plugin and no public API. Built a full pipeline: Cloudflare Worker catches the order webhook, a Chrome extension auto-fills the GLS shipping form — zero manual entry per shipment on opgbrankomarinov.com.
const order = await parseWebhook(req);
const addr = normalizeAddress(order.shipping);
injectGLSForm(addr); // zero manual entry ✓
- Chrome Extension (Manifest v3) + Cloudflare Worker
- Vue.js DOM bypass via
nativeInputValueSetter - Address parser, phone normalizer, email-to-name fallback
Scam Checker HR — Phishing & Fraud Detection No Backend
Croatian-language tool that detects phishing & scams across four vectors: text analysis, URL checking, email header parsing (SPF/DKIM/DMARC), and file scanning with magic bytes + SHA-256. All processing is client-side; threat feeds proxied through Cloudflare.
const MZ = bytes[0]===0x4D && bytes[1]===0x5A;
const sha256 = await subtleCrypto.digest('SHA-256', buf);
malwareBazaarCheck(sha256); // hash never stored ✓
- Google Safe Browsing v4 · URLhaus · MalwareBazaar · RDAP
