Charlie Herrera · Product Design Engineer
From Bogotá, for LATAM and beyond
I design and build digital products with AI. From idea to MVP in weeks, with product judgment behind every decision.
Principal author of Falcux AI-First. Design, code, and method in one place.
Explore what we can buildSometimes you need to build. Sometimes, a better process. And sometimes, a good conversation before the first line of code.
From idea to product
You have an idea and need to make it real. I design, build, and launch your product without making you coordinate three providers.
Product design, a visual system, development, integrations, and launch. The repository and documentation are yours from day one.
DesignOps + AI-First
Your team is already using AI. Now it needs a method that keeps context, quality, and decisions connected.
Workflow audit, a tailored Falcux AI-First, onboarding, and support so your team can work independently.
Idea clarification session
An idea can still go in many directions. We give it focus in a 60-minute session, followed by a report with actionable decisions.
A structured, recorded conversation, an actionable report within 48 hours, and an optional follow-up to review progress.
AI brings speed. Method gives it direction.
I’m the principal author of Falcux AI-First: a public methodology for building software with AI agents without losing context between sessions.

The person behind Falcux
I’ve spent over 14 years designing digital products. Today, I also write the code that brings them to life. Connecting design and engineering lets me carry an idea through to its smallest details.
I work independently, choosing projects carefully and setting clear expectations. You work directly with the person who designs, builds, and makes decisions alongside you.

Get to know my storyA typical project takes 4–8 weeks, depending on scope. First, we decide what the first version needs and what can wait. Speed matters when we’re building the right thing.
I work independently. You have one point of contact for product, design, and code. If your project needs a larger team, we discuss that from the start.
Yes. I work remotely and mostly asynchronously, in Spanish and English. We agree on times for check-in conversations.
The project includes two weeks of post-launch support. You keep the repository and documentation. If you need ongoing support, we agree on a separate arrangement.
Yes. The full methodology is free to read. The consulting service helps teams adapt and implement it in their own context.
