Daniel Ballesteros · Data & AI Engineer

All your business information
in one place.

I extract data from all your tools, unify it in one place, and build the software your team and AI agents use every day.

What I do
  1. 01

    Data infrastructure

    I extract data from all your applications and unify it in a single database — always up-to-date and fully traceable down to the origin.

    • Multi-app extraction (ERP, CRM, GA4, APIs)
    • Central database
    • Automated pipelines and monitoring
  2. 02

    Software & reporting

    On top of that database I build the operational apps and reports the team and leadership use every day — built around the real process, not a generic SaaS.

    • Custom operational apps
    • Real-time executive dashboards
    • Forms, flows and internal tools
  3. 03

    AI & automation

    I build AI agents that work inside your operation — specialized by area, connected to your database and able to close entire processes without human intervention.

    • Domain-specialized agents
    • MCPs over the database
    • Process automation
