AI-First Systems Engineer · From Silicon to Cloud
Cluj-Napoca, Romania · 35+ years shipping production systems across embedded, robotics, IoT, mobile, web, and backend. AI-first development is my current methodology — multi-agent orchestration pipelines that automate complex workflows end-to-end across the whole stack.
Loomcycle — open-source agentic runtime in one Go binary. Six provider drivers (Anthropic, OpenAI, DeepSeek, Gemini, Ollama cloud + local), fourteen built-in tools, MCP-native. UNIX-style operator/caller trust separation. Apache-2.0.
JobEmber — multi-tenant AI job-search SaaS, and the first production user of loomcycle. Pre-launch.

At Waverley Software (2014–present; Lead Full-Spectrum Developer since 2024):
- Multi-agent robotics ML pipeline — 7-agent orchestration for automated data collection, log analysis, model retraining, dry-run validation, and deploy/no-deploy recommendations. ROS2, Python, SQLite, Claude Code CLI agents.
- Real-time vision systems — Robotic Air Hockey on Jetson Orin NX with Basler + RealSense cameras and xArm 5 control. ROS2, C++, Python, OpenCV.
- Medical robotics — multi-arm path planning (NDA, Swiss client) — multiple Cartesian robot arms operating simultaneously in a constrained 3D medical environment. Dart, C++.
- Mobile GPU-accelerated ML — real-time video processing and ML inference pipeline. TensorFlow, MediaPipe, native OpenGL/Metal shaders.
- IoT, end-to-end — ESP32 firmware (ESP-IDF) → AWS IoT → Flutter mobile clients. Solo-shipped multiple smart-device products concept-to-production, including AromaTru.
- Autonomous home pet robot (in progress) — Nav2/SLAM, LiDAR, CV, ML object recognition, robotic arm. Full hardware design + 3D printing + ROS2 software stack.
- ROS2 MoveIt 5-DOF manipulator — simulation and control with the MoveIt stack.
- IoT devices, PCB design → production — smart irrigation, gate lock, water tank controller. ESP32/ESP8266, solar-powered, MQTT, custom PCBs.
Senior → Lead Android Developer & Architect at Waverley Software (2014–2024) before stepping into the full-spectrum lead role. Earlier: Android architecture (smart watches, medical devices, BLE wearables, Jibo social robot). VoIP development (PJSIP). Financial and trading systems (algorithmic trading robots in C#, LIBOR pricing engine in C++/STL, EM-bond monitoring in Java EE). Embedded systems (bare-metal 8088 fiscal cash register, Win32 enterprise with COM/ATL).
I also prototype hardware end-to-end — schematics and PCB design, CAD/CAM, 3D printing, laser cutting, CNC milling.
Education — Engineer's Degree in Computer Science (Automated Systems Programming), Taganrog State Radio Engineering University, 1987–1992. Languages — English (fluent) · Russian (native) · Romanian (learning).
