Sheet 02 / 08 — ManifestoScale 1:1

For more than ten years I have turned fuzzy ideas into software real people use. By day I build product for the small businesses that get paid with Bold. By night I build Taply, AI agents that serve the customers of small businesses. I like starting from a blank page, asking why until I understand the problem, and shipping something that works by Monday.

Made in Venezuela

Born in Táchira. Ready to build for Venezuela again.

For more than ten years I have built technology away from home: products, teams and clients in Colombia. Now I want to put everything I learned at the service of the country where I was born.

Venezuela needs products built from scratch, fast and with AI, that serve its people and the businesses that keep opening every day. That is where I want to be.

Sheet 04 / 08 — FacetsCross section

Engineer

Frontend architecture that holds up to product, teams and scale.

  • Internal libraries for JSON-configured forms and tables, reused across the whole product.
  • Serious authentication: Auth0 with webhooks, SAML, and route guards by role and permission.
  • Angular, React, Next.js, Astro and Svelte up front; Node.js, NestJS and Elixir behind.
Material: TypeScriptTolerance: 0 bugs in prod

Builder

From idea to a product that gets paid. Without waiting for permission.

  • Taply: a SaaS of AI agents for small businesses, built from scratch and on the market.
  • Proposed and shipped a landing-page generator for partners that removed the need for developers.
  • White-label products, including one for Repsol, from architecture to delivery.
Method: ship and measureCycle: weeks, not quarters

Curious

I take tools apart to see how they work and what else they can do.

  • I use coding agents and AI every day to work better and faster.
  • I experiment with knowledge graphs over codebases to give agents memory.
  • I built automatic design-system extractors with Puppeteer and Selenium.
Favorite question: why?Second: what if…?

Business

Code is the means. The result is someone selling more or working less.

  • Designed Taply's plans, pricing and segmentation by business type.
  • Led frontend teams: onboarding, technical reference and the bridge to product, design and backend.
  • I build for small businesses because they gain the most when technology gets simple.

Taply. AI agents for the shop around the corner.

Barbershops, vet clinics, bakeries and auto shops lose customers because they can't reply in time. Taply gives them an agent that answers with the business's own information and rules, books appointments and drafts posts, while the owner focuses on the craft.

I built it from scratch: product, architecture, integrations, pricing, and even the tool that produces its marketing videos.

What I'm taking apart right now.

Exploring

An AI assistant for every employee

An agent that answers in Slack for people stuck in meetings: project status, who owns what, who to ask.

Prototype

Memory for coding agents

An MCP server that indexes repositories into a persistent knowledge graph so agents understand code without rereading it.

In use

Taply Studio

A local platform to generate Taply's social videos: aha moments, real product screens and emotional pacing.

Built

Design-system extractor

Puppeteer and Selenium toolkits that capture tokens, responsive styles and component states from live sites.

Exploring

Sensors for corner stores and chains

Fridge temperature monitoring with automatic alerts, so no product spoils without anyone noticing.

Exploring

Augmented reality for events

Technical evaluation of an AR activation for a cycling festival: build it in-house or with an agency, and how.
