I make software that has to work first thing on Monday. I built the self-service system behind the Electoral Tribunal kiosks, where Panamanians identify themselves with their fingerprint and get a duplicate ID card or a certificate without queuing, and the queueing system behind the 2021 vaccination rollout. Now I am working on two products: Andre, an agent that answers a business’s WhatsApp, books appointments and hands the sales team leads that are already qualified, and El Empleado Juan, which tracks attendance with face recognition and gets payroll ready.

Now: Andre and El Empleado Juan.

Now

Projects

Everything before, from the latest to the first.

What I do

And where I did it.

Symbolic mathematics from scratch

Parsing, expression trees, an inference engine and knowledge representation, with no library solving it underneath. A system that does not compute the answer: it reproduces the reasoning and explains it step by step.

One Second Solver

Computer vision in production

An end-to-end pipeline of my own: detection with MTCNN and RetinaFace, embeddings with FaceNet and ArcFace, anti-spoofing, transfer learning and edge deployment. On cheap hardware and integrated with third-party terminals — which is where most vision projects fall over.

El Empleado Juan

Mission-critical identity

Systems where being wrong about who someone is not an option: legally valid documents, payment taken on the unit itself, continuous operation and every transaction auditable. No "we will fix it next sprint".

Electoral Tribunal

Operations in the physical world

Software governing people moving through a building in real time, across several sites at once, with a protocol to meet and no rehearsal. When somebody is waiting in front of it, availability is not a metric: it is the product.

National vaccination

Distributed architecture at scale

Microservice ecosystems with streaming and real-time processing: Node.js, PostgreSQL, MongoDB, Redis, Kafka, Spark and Flink on Kubernetes over AWS. Multi-tenant by design, which is the one thing you cannot retrofit later.

Fluyapp

LLMs from the inside, not the API

A Llama-style decoder-only model written from scratch: tokenisation, attention, training. It is what lets you know why the model does what it does, and above all what its architecture cannot give you no matter the prompt.

Writing

RAG agents with real customers

Retrieval, embeddings, tool use and integration with real systems, evaluated against questions with known answers. Agents that query live data and have an explicit path to saying "I do not know" instead of making it up.

RAG agents

Agents that operate, not just talk

Agents that qualify, book and move the pipeline on real systems, with the AI proposing and the system validating: typed schema, the user’s own permissions and constraints in the database. Stateful flows on LangGraph, multi-tenant with Row-Level Security and the official WhatsApp API.

Andre

Complete product, end to end

From a WhatsApp bot to a multi-tenant platform with three capture layers, statutory payroll with auditable premiums, feature flags, licensing and CI/CD. A product with paying customers, not a prototype.

El Empleado Juan

  9. 2012 Winner of a national innovation contest.
  10. 2010 Technological University of Panama. One Second Solver begins: a symbolic language app that worked like a teacher.

About

I am Colombian and live in Panama. I started at university with a symbolic language app that worked like a teacher, was CTO at XPLOR, co-founded Fluyapp and El Empleado Juan, and now I am working on Andre.

As a kid I took everything apart to see how it worked. Still do, except now it is AI models.

Education

MSc in Computational and Mathematical Engineering

Universitat Rovira i Virgili, Spain. Before that, Computer Systems Engineering at the Technological University of Panama.

Education

Applied statistics

I help physicians in Panama with the statistics in their theses: the analysis design, the models and the figures they have to defend.

Writing

I write when something took me a while to understand.
All writing

For government

Work in the public sector? I have a concrete proposal, with two government systems already running behind it.

Read the proposal

Write to me

If you are thinking about building something with AI and want to talk it through with someone who has put it into production, write to me. I answer myself.
