From Goldsmith to Builder: Why I'm Building in Public

I didn't start as a developer. I started working metal with my hands. Today I build software. This is my story.

From Goldsmith to Builder: Why I’m Building in Public

I didn’t start in tech. I started working metal with my hands.

I was a goldsmith by trade. Then a professional photographer for 13 years. Later a trainer for LinkedIn Learning, teaching about NAS servers and storage. Then a Python developer at NTT Data. And now I work at KEO Connectivity with IoT protocols for energy systems.

Strange paths. But all connected by the same thing: obsession with understanding how things work, and then making them work better.

The Pattern

When I was a photographer, I couldn’t afford the equipment I needed. So I improvised. Built supports, modified accessories, made what I had work.

That same impulse led me to build my own 3D printer from scratch. To tinker with Arduino. To learn Python to automate workflows at Qloudea while managing social media and providing technical support.

The pattern is always the same: identify a problem, obsess over solving it, learn whatever it takes to fix it.

Why Now

After years solving problems for others, I decided to solve problems for myself. Build my own products.

I don’t have an MBA. I don’t have funding. I don’t have a team. I just have experience building things, teaching what I learn, and an abnormally high tolerance for not knowing what I’m doing.

And I decided to do it in public because:

  1. Accountability: It’s harder to quit when you share progress publicly
  2. Teaching: I’ve always been a trainer. Sharing what I learn is part of who I am
  3. Community: I want to connect with other Spanish builders on the same journey

What I’m Working On

Currently focused on WarrantyHub, a digital warranty management platform for home users.

Why warranties? Because I saw the problem in real life: chaotic management with papers, Excel, lost emails. And because there’s room for a Spanish solution that understands the local market.

I’m using AI aggressively to accelerate development. Not because it’s trendy. Because when you’re sole developer, sole marketer, sole product manager, sole support, you need every advantage you can get.

What to Expect

I’ll share launches, technical learnings, product decisions, and failures (because they teach more than successes).

Don’t expect generic motivational posts or recycled X threads. This is documentation of a real journey.

If you’re a builder, this is also for you.
