About

I'm Alejandro Sanabria Villescas, a Forward Deployed Engineer at Wonderful in Bogotá. I sit with customers, turn real workflows into AI agents, and wire those agents into the systems they already run.

I've been working in technology since 2012, about 14 years: I co-founded Brand Spa, then spent more than eight years on mobile at Platzi, and now I'm at Wonderful. On the side I ship Cifro, a budget app for iPhone, and small CLI tools for App Store releases.

More on where I've worked and the apps and tools I've built.

I build AI agents for Wonderful's customers and wire them into the systems those customers already use.

Where I've worked

iOS skills for coding agents

open source

Instructions I wrote for Claude Code and OpenClaw so they build SwiftUI features with clear feature boundaries, GRDB for storage, tests, and a visual check at the end.

Cifro

finance app

A free budget app for iPhone. You log an expense by typing "15 lunch", by voice, or by scanning a receipt. No account, no bank login, no ads. The AI runs on the phone with Apple Foundation Models.

Release tooling

CLI tools

Two CLIs I use to ship my own apps. appstore-tools uploads builds and edits App Store metadata. screenshots-ios takes the same simulator screenshots every time.

I co-founded a digital agency and ran its engineering for almost five years. B2B products for clients: CMS platforms, e-commerce and quoting systems.

Platzi

iOS & Android lead

8+ years. I joined as one of Platzi's first mobile engineers and ended up leading iOS and Android. We moved the app from React Native to native Swift and Kotlin. Apple recognized the team's Foundation Models and Liquid Glass work.

What I'm Building Now

Agents at Wonderful, updates to Cifro, and the release tools I use for it: appstore-tools and screenshots-ios.

I still read the code. If I can't judge a trade-off, I shouldn't be the one approving it.
