AI & AI Agents — We build intelligent systems that go beyond basic automation. Our work includes autonomous AI agents, LLM integrations, retrieval-augmented generation (RAG), computer vision, and predictive ML models. We design AI that operates inside your existing workflows — not as a demo, but as production infrastructure. Odoo ERP — We handle complete Odoo implementations on Odoo.sh and on-premise: multi-company configuration, localisation (GST, e-invoicing, TDS for Indian businesses), custom module development in Python, and integrations with payment gateways, logistics, and third-party APIs. From initial setup through ongoing support. IoT, PCB Design & Embedded Development — We design and manufacture custom hardware. PCB layout and fabrication, microcontroller programming (Arduino, Raspberry Pi, ESP32, STM32), sensor networks, MQTT/cloud connectivity, and production-ready firmware. We take projects from concept sketches to assembled, tested boards. We also deliver across the full web and mobile stack — React, Angular, Flutter, Django, Node, Laravel — with deployments on AWS, GCP, and Azure. Our strongest work happens where these worlds overlap: AI models running on edge devices, ERP systems fed by IoT sensors, intelligent dashboards pulling from both cloud APIs and embedded hardware. If your project crosses boundaries, we're built for that. Reach out and tell us what you're working on. weniger -
