About
SelftaughtAIengineerwhostartedonasalesfloor.
I'm Juan José Lozano Vargas. I've spent the last five years building technology from the ground up inside a real company, with real budgets and real deadlines. I started on the sales floor learning the business inside out, moved into running key accounts, then took on the full digital transformation of the company. Since 2025 I'm CEO with a clear technology mandate.
01
How I got here
Suraelec is a wholesale electrical goods company in Bogotá. I joined in 2017 as a sales representative for key accounts. Two strategic clients, a catalog of thousands of products, and three years of learning the business by carrying it on my shoulders.
In 2020 I started learning to code. Within the year I had taken ownership of the company's entire digital ecosystem. There were no systems when I started this phase, only spreadsheets and habits. We migrated SAP to Odoo 19, brought in Microsoft 365, shipped the first real BI dashboards leadership had ever seen, and made n8n the automation backbone of the company.
In January 2025 I became CEO with a technology mandate. The first year shipped a 5% net profit lift, driven entirely by process optimization across sales, administration, and logistics. Every system I've built since started with the same question: what is the manual, painful, or slow thing that technology could fix right now?

How I work
Find the painful thing first
The fastest wins always sit on the slowest, most manual processes. I find them by sitting next to the person doing the work, not by reading a process diagram.
Ship into production, not into decks
I'd rather have a small thing running in production than a polished proposal for a bigger thing that never lands. The systems on this site are all running today.
Real numbers, real accountability
I built inside a company that owned the budget and felt the cost of every wrong decision. That's the bar I use for every project: would I sign off on this if my name were on the P and L?
Documentation is a deliverable
Runbooks, SOPs, integration diagrams. Your team owns the system when I'm done, and that means they need to be able to read it.

A bit about me, outside the work
I'm a father first. My daughter was born two years ago and completely changed the way I think about time, priorities, and what matters. It also made me more focused: when you have limited hours, you get better at using them.
I cycle regularly, which is where I do most of my thinking. I'm passionate about photography and videography, and I document adventure sports whenever I get the chance. Being behind the camera on a climbing trip, or filming a mountain bike descent. There's something about capturing a moment that forces you to actually pay attention to what's happening.
I read constantly, mostly across technology, business, and human behavior. The best ideas for technical problems usually come from somewhere completely unrelated to technology.
I'm someone who builds things. Not because it's my job, but because I genuinely cannot help it. If I see something broken or slow or inefficient, my first instinct is to figure out how to fix it. That's probably why I ended up doing this kind of work.
