Career
Executive Summary

Medellín Web Soluciones·Medellín

The architect companies call when the system can't fail.

Software architect with 10+ years designing and operating systems that can't afford to fail — from critical platforms under corporate standards to the new generation of agentic AI infrastructure. I prototype when the problem calls for it, but my work is measured in production: real clients, 24/7 operation and end-to-end accountability.

End-to-end products

Through Medellín Web Soluciones I design, build and operate real systems — not demos — with clients and 24/7 operation.

Architecture principles

Local-first & Security

01

AI that runs inside your perimeter when data privacy isn't negotiable — no dependency on a third-party API that can fail or leak.

High availability

02

Systems designed to stay up: no single point of failure, built to survive scrutiny from a corporate platform team.

Observability

03

Metrics and traces at every layer. If something breaks, I see it before the client does — and prove it with evidence, not guesswork.

24/7 automation

04

Agents and containers that absorb repetitive operational work, so your team can focus on what actually moves the needle.

Working with Spain / EU

Remote first. Relocation if needed. Clear contracts.

Remote or relocation

Based in Medellín. Prefer 100% remote with CET overlap. If the role requires presence, I can relocate to the contract city (work authorization with company sponsorship).

Contract model

Spanish permanent contract or B2B contractor. Google Meet, end-to-end ownership and senior banding — not commodity mid-dev rates.

GDPR and data

Privacy by design: local-first when it matters, scoped processing and guardrails. Ready to discuss AI Act / GDPR compliance on the technical call.

Language

Professional Spanish (neutral ES/LatAm) and technical English for international teams.

Products & Ventures

My own products, kept separate from my career track.

Nova, the lab and MWS AI are my own initiatives, where I push agentic architecture into production. They live here rather than mixed into employment history, so it's clear what is career and what is product.

Live orchestration

Agents laboratory

Nova: an army of autonomous agents with a CEO, divisions and specialists. See how real work is orchestrated 24/7 — not a chatbot, but an operable system with traces, cost and roles.

For WooCommerce agencies

MWS AI: recurring margin — not another architecture freela.

If you're an agency or reseller in Spain, this isn't a pitch to hire me as a Solutions Architect. It's a white-label SaaS: a 24/7 sales/support agent with RAG over live Woo inventory, human handoff and annual Growth/Enterprise plans.

  • Live inventory (stock, sizes, prices) — fewer hallucinations than a generic chatbot
  • WordPress plugin + license; no third-party API keys in the client's store
  • Agency channel: volume / white-label for recurring margin
  • 15-minute demo oriented to your Woo client portfolio
