What I'm looking for

I want to bring my in-house AI and automation experience to a European company, remotely.

At COSBE SAC / La Nuestra Group, I work with department heads to identify worthwhile automation projects, build and deploy solutions, and keep them running in production. My n8n chatbots have handled close to 50,000 customer-service and recruitment messages.

I built NEXO, the company ERP, with its employee clock-in kiosk now in daily use by about 80 employees. I also built a delivery app that records about 2,000 deliveries a month, along with tools for field marketing and monthly AI-cost reporting.

Before this, I ran production operations at Unitech in the Netherlands, and maintained communications and onboard network systems in the Royal Netherlands Navy. I’m now looking to bring my in-house automation experience to a European company, remotely.
