About

Full-stack indie hacker from Bogotá, Colombia 🇨🇴. I build practical open-source tools that developers actually enjoy using. Creator of MTC (Modular Template CLI for .NET), AerionOS (browser-based OS simulator), WaitlistMailer and now SendDock — a modern self-hosted email marketing platform with visual editor and BYO SMTP. Passionate about clean code, developer experience, privacy-first software and making powerful tools accessible without crazy pricing.

SendDock - Self-hosted email marketing. BYO SMTP, zero cost per email.

SendDock is an open-source (AGPL-3.0), self-hostable, API-first email marketing platform. Bring your own SMTP and send unlimited emails at zero cost. Modern UI with GrapeJS visual drag-and-drop builder, full REST API, project isolation, open/click tracking, campaigns and bulk imports. Extremely easy Docker setup in under 30 seconds. Pro features (Analytics + webhooks) unlocked with license. The beautiful and powerful Listmonk alternative for devs and teams who want privacy and control.
