Full Stack Lead Engineer at ZNova Studio

About

Full-stack engineer who builds SaaS platforms and fast marketing sites, from the database schema to the front end. I work mostly in TypeScript, Node.js, PostgreSQL and headless CMSs, and lately on AI work like RAG pipelines and automation. I work at ZNova Studio (znovastudio.com), a small software, AI and IT studio. We also build free tools for developers and small teams. The first is an SPF & DMARC checker and generator that runs entirely in your browser.

SPF & DMARC Checker - Find out if scammers can send email as your domain

Type your domain and see in seconds whether anyone can send email pretending to be you, and exactly what to fix. • Checks SPF (including the 10-lookup limit) and DMARC (RFC 9989) • Plain-English results, not raw DNS output • Knows 30+ senders: Google Workspace, Microsoft 365, Zoho, Mailchimp, HubSpot and more • Companion generator builds safe SPF + DMARC records to copy into your DNS • Runs in your browser: no sign-up, nothing stored
