About me

I am a Systems Engineer and Full Stack Developer with more than 15 years of experience designing, building and maintaining business software: ERP/MRP/CRM systems, AI-powered SaaS platforms, academic information systems and data pipelines.

Today I work at AJAW, developing AJAW MRP (Axelor, Java, PostgreSQL) and AJAW Data AI (Angular with OpenAI, Gemini, Twilio and Stripe integrations). I enjoy owning a product end to end: requirements analysis, data modeling, REST APIs, web interfaces, testing and deployment.

Alongside development, I have complementary experience in training: I have taught programming at universities and in the Misión TIC 2022 program, and I co-authored three technical papers about systems I built. It shows in how I document, explain technical decisions and support other developers on the team.

I work remotely with Scrum, Jira, Git and Docker, and I focus on maintainable code, clear interfaces and continuous delivery.

Featured projects

Current work at AJAW: four production products, from manufacturing ERP to AI sales automation and data pipelines.

AJAW · ERP / MRP / CRM

AJAW MRP

ERP, MRP & CRM for manufacturing companies

The problem: Manufacturing companies need to run the whole business cycle (sales, product design, production, shop floor, quality, stock) in one system adapted to real plant operations.
The solution: A multi-tenant SaaS ERP/MRP/CRM on Axelor Open Suite 7 (Java 11, XML, JPA/Hibernate, PostgreSQL) with 20 new custom modules and customized standard modules, used by 11 manufacturing companies.
My role: Full stack developer in a 6-developer team: designed and built the new modules, customized CRM, sales, purchasing, stock and manufacturing, and optimized processes, queries and views.

AJAW · AI Sales Prospecting

AJAW Data AI

AI sales prospecting platform for Latin America

The problem: Small and mid-sized sales teams in Latin America spend their time searching for leads and following up manually across several channels.
The solution: A B2B prospecting SaaS with AI agents that call, send SMS, WhatsApp and Instagram messages, follow up and move deals through the pipeline. Angular 18 frontend and a Prospecting AI module on a dedicated multi-tenant Axelor backend.
My role: Built the Angular frontend (standalone components, RxJS, lazy loading, charts, PDF/Excel export) and the backend module, and integrated OpenAI, Gemini, ElevenLabs, Twilio, Stripe, Chatwoot and n8n workflows.

AJAW · Monitoring Dashboard

Migration Control Panel

Monitoring of the LATAM data scraping and migration pipeline

The problem: A large scraping and migration pipeline needs constant visibility: which sources are healthy, what each country’s data law allows, and what is ready to move to production.
The solution: A real-time control panel in Angular backed by a Node.js/Express API on SQLite, with a live event stream (Server-Sent Events), sources catalog with robots.txt policy and rate limits, work-order queue, migration batches and reports.
My role: Built both the Angular dashboard and the Node.js API running on a VPS, consumed through a secure tunnel.

AJAW · Data Processing

CSV Tracker

Enrichment and cleansing pipeline for scraped CSV data

The problem: CSV batches of scraped business records need cleansing and enrichment before production, without ever corrupting the original data.
The solution: A Python pipeline in layers: deterministic validation first, then web search, and an LLM only for ambiguous cases. Every change gets a confidence score, a source and an audit trail; a new value needs two independent sources and a checkpoint is saved after every row.
My role: Built the Python pipeline, the Node.js/Express API on SQLite and the Angular panel to upload files, follow jobs in real time and review every change.
