Our core is agentic AI: autonomous agents, LLM integrations, RAG pipelines, and predictive ML models designed to operate inside your existing workflows and make real decisions. What sets us apart is the stack we pair it with. We implement Odoo ERP end-to-end, design and manufacture custom IoT hardware, and deliver across the full web and mobile stack. This means we can put AI where others can't — on edge devices, inside ERP workflows, reading live sensor data, acting on it in real time. We work across React, Flutter, Django, Node, and deploy on AWS, GCP, and Azure. Our hardware work spans PCB design, ESP32/STM32 firmware, and MQTT-connected sensor networks. If your project crosses boundaries — AI that talks to hardware, agents embedded in enterprise software, intelligent systems that need to actually ship — that's exactly where we do our best work. Tell us what you're building. menos -
