Three beans in the same cup

Technology
From supporting networks and servers to building products with React, Next.js and Supabase.

Philosophy
Graduate and teacher. I keep asking what technologies do to the way we think.

Entrepreneurship
My own startups and other people’s: from idea to prototype, and from prototype to first customers.
Six steps, one cup and a journey
Every step of the brew is a chapter. Scroll slowly: coffee is never in a hurry.
Step 01Grind0:00
IT support
It all starts with the bean
Before writing a single line of code I spent years among cables. I’ve been in the tech industry for over nine years, supporting networks, servers and laptops.
Grinding is the step nobody photographs, but there’s no cup without it. I still love talking about which computer to buy, or how to make yours run again.

Philosophy
While it boils, you read
I hold a degree in philosophy and I teach it. My thesis was on the technology of the Greek alphabet: before chips there were letters, and with them the way we think changed.
Out of it came a book chapter, “Alphabetic technology, technological thinking”, and a talk, “Alphabetic technology, the origin of philosophy”.

Digital marketing
The first pour wakes the coffee up
During the pandemic I was already working in tech, but my growth had been linear until it stalled. I subscribed to Platzi and grew in digital marketing.
On top of my job I started freelancing: WordPress websites and social media management.
With Platzi, I was my own startup.
- Personal branding
- Content marketing
- E-commerce
- Community management

Step 04Pour1:30
Software development
In circles, no rush
There was a path I had run away from for a long time: building software. I was terrified of code without ever having written a line.
Now I love it. It’s a gigantic universe, and that’s where I understood what “never stop learning” means.
Like any startup, you’re allowed to pivot, and it’s never too late to learn.

Entrepreneurship
Two cups: one is yours
At Kameliapp I learned about the ecosystem and about leading a development team. With Meishi Cards I built the platforms for my own startup: the app in the stores, the web version and the admin panel.
Today I run kofitime, to discover specialty coffee, and SkillsWater, a platform to learn humanities, technology and English.

The cup is the excuse

Questions left at the bottom of the cup

Stories
