Software & AI Engineer Consultant

Experience defines architecture.Architecture refines experience.

I design and build AI applications and platforms where UX and engineering are decided together, from start to finish.

The problem

You got used to solving it that way. It didn't have to be the only way.

Your company grew using whatever was available: spreadsheets, generic SaaS tools, systems that almost fit.

  • Every area has its own spreadsheet, its own truth, its own version of the data.
  • That process works today, but you won't be able to scale it like this.
  • Much of how day-to-day work gets solved lives in your people's heads, not in a system.
  • You want to give your customers a better experience, but you think it's out of reach.

That's behind you now. Today your company can have its own applications, much faster and at a lower cost.

The solution

How I solve it

Diagnosis, architecture, and AI-assisted development, in short cycles.

Systems for your team

Systems for your team

Backoffice, operational tools, internal AI agents. The system that replaces the TMS or ERP surrounded by parallel spreadsheets.

Portals and apps for your customers

Portals and apps for your customers

Mobile apps and web portals your customers use directly. The external face of your operation, designed so they don't have to adapt to something generic.

I work in short cycles: each one delivers real value and builds on the previous one. AI accelerates execution, but every decision — architecture, design, quality — I review and approve myself.

Selected projects

Systems for teams, portals, and apps for end users, where a failure has real consequences.
