Lately there has been a lot of buzz around the concept of Vibe Coding—that way of building software where the friction between idea and execution practically vanishes thanks to AI assistance. After applying it intensely for about three weeks, I can genuinely say the result has been incredible: I have launched three fully functional, production-ready projects. The sheer velocity of iteration has been the secret sauce allowing me to juggle three distinct products in parallel.

Here is what I’ve been working on:

  1. Jombo.es: A community-focused carpooling platform that is completely commission-free. The mission is to enable shared, direct transportation in an ethical and accessible way.
  2. Truek.xyz: An item bartering and exchange platform. In a world full of clutter and consumer accumulation, Truek facilitates trading what you no longer use for what you actually need.
  3. Enkimail.com: A high-throughput email queue processor designed specifically for email marketing. It allows you to dispatch bulk campaigns efficiently and with fine-grained delivery control.

The Tech Stack

Across all three projects, I stuck to a cohesive and repeatable stack, allowing for extreme agility:

  • Backend: Ruby in API-only mode. Ruby’s developer ergonomics and velocity remain second to none for getting ideas off the ground.
  • Frontend: Next.js. All frontends are deployed on Vercel’s free tier, leveraging their seamless Git integration and global CDN performance.
  • Backend Infrastructure: All backends run side-by-side on a single virtual server orchestrated via Coolify. For those unfamiliar, Coolify is like running your own self-hosted Heroku—a godsend for automating container builds and SSL without exorbitant PaaS bills.

The Infrastructure Challenge of Enkimail

The Enkimail project was naturally the most demanding on the systems side. I used Docker to spin up a customized Postfix mail transfer agent directly integrated with the application queues.

Anyone with experience in email marketing knows that sender IP reputation is everything. I was extraordinarily fortunate to secure a sparkling clean IP not listed on any major blocklists, which is essential to ensure emails land straight in the inbox from day one.

These three weeks have served as a powerful reminder: with modern developer tools and the right mindset, the distance between “I have an idea” and “I have a shipped product” has never been shorter.
