/ Product designer — Design engineer

SebastiánCastiblanco

I’ve been designing digital products for eleven years. Since last year, I also build them.

I find the point where your user drops off, redesign that point and leave it up and running. Banking, fintech and digital identity — where an interface decision is also a risk decision.

I’ve designed product for

  • Davivienda
  • Banco Santander
  • BBVA
  • Siigo
  • GSE

Santander and BBVA through OpenSistemas, Spain. Davivienda, Siigo and GSE under direct contract.

— 02 How I work

Fewer handoffs, one person accountable for the problem.

For ten years I delivered Figma files for someone else to interpret. Along the way the same thing always got lost: the intent, and with it, fidelity to the project. With Fiable I stopped doing that — I defined the data schema and the security policies, built the application, and integrated payments, e-signature and background checks.

I use artificial intelligence as a technical execution team: I define architecture, scope and security criteria; AI compresses delivery time; I review every delivery. I don’t come from a programming background. What I bring isn’t syntax — it’s product and architecture judgment, and the discipline not to accept what I don’t understand.
