Hi, I'm Juan.

Architect and AI Engineer. I build the software a US builder uses every day.

Who I am

I come from architecture, and today I build software for the job site. That background is what makes what I build work in the field.

I work as AI Engineer & Platform Owner at Drake Construction, through Emapta: I design and maintain Drake Hub, the platform the team uses to run job sites, finances and estimates. Before that I led a BIM team in Berlin, where I learned that good coordination is what separates clean deliverables from rework, and I bring that same discipline to software. On the side I build AI products: six apps and tools in production, from fintech to a Catholic app.

What I do

Four things, done well.

Product

AI products

Complete apps with Claude, RAG, voice and vision, from idea to production.

Web

Web & performance

Fast sites, technical SEO, image pipelines and security.

Process

Automation

Browser bots and internal tools that save real hours.

Job site

Construction coordination

Schedules, documentation and communication between US teams.

Method

How I build with AI.

Vibe coding with job-site discipline: AI writes the code, I direct, review and answer for the result.

Product first

Problem, user and flow before a line of code. I design from real references, not templates.

Directed AI build

Claude writes the code; I set the architecture, review every round and make the calls.

Tested like a real user

Every change is checked on a real screen, mobile included, with real data and accounts.

Ship and maintain

Deploy, domain, analytics and improvement rounds with real users.
