What I'm looking for

I'm looking to build C++/Qt products and local AI systems, with opportunities to solve architecture, performance, and integration challenges.

At IVA-Technologies, I build multi-container AI architectures that isolate Llama.cpp and LangChain for local LLM inference, tool integration, and reduced dependence on commercial cloud APIs. I also develop low-latency Qt 5/6 and QML applications and reproducible Docker-based development environments.

Previously, I delivered C++/QtQuick applications for ROLIS(GlobalPorts) and independently built around five Windows/Linux QtWidgets and QtQuick applications at Kalashnikov. My work includes legacy-system refactoring, customer requirements, OpenCV, GDAL, Linux networking, and C++ client-server development.

Engineered multi-container AI architectures by isolating Llama.cpp and LangChain into separate Docker containers, enabling microservice-based LLM inference and tool integration. Implemented LangChain Tool Calling to connect open-source, locally hosted LLMs with external tools and functional utilities.
