Senior AI & LLM Systems Engineer | Edge-AI Specialist
Specializes in AI Chatbot Development
AI & LLM Systems Engineer | Edge-AI & Environmental-Aware AgentsSenior AI & LLM Engineer with 5+ years of experience fusing cutting-edge language models with real-world perception. I create autonomous AI agents that don’t just chat — they see, hear, and feel their environment through my custom sensor hardware, reason in real time, execute actions, and alert users with natural spoken voice (TTS) or instant messages when something important happens.
Italian engineer based in Spain, owner of a registered EU company (legal invoices).
What I deliver
- Situationally-aware AI chatbots & agents that achieve true environmental awareness via my proprietary multisensor boards (air quality, temperature, flood, fire, motion, gas, sound, cameras, IMU, etc.).
- The LLM receives live context, decides autonomously, calls tools/functions (open valve, move robot, send SMS/Telegram, trigger alarm) and speaks warnings in natural language using on-device TTS — even offline.
- Full LLM lifecycle: dataset creation → continued pre-training → fine-tuning → quantization → deployment from cloud to ultra-low-power edge (NXP i.MX/ nRF54 / Nvidia Jetson / Raspberry Pi).
Core AI/LLM skills
- Fine-tuning 8B–70B models (Llama-3, Mistral, Grok, Phi-3, Gemma) with Unsloth, Axolotl, TRL
- Inference: vLLM, TensorRT-LLM, llama.cpp, MLC, ExecuTorch
- Real-time voice: Whisper + Whisper.cpp + Coqui (TTS) + Silero VAD
- Multimodal & RAG on edge (LLaVA, Phi-3-Vision, Chroma/FAISS)
- TinyML & on-MCU inference (Cortex-M33)
Hardware & embedded expertise that gives the AI real senses
- Custom ultra-low-power sensor nodes (5–20 µA sleep) with BLE, LoRaWAN, LTE-M
- ARM Cortex-M33 specialist (Nordic nRF52/53/54/91, STM32, NXP)
- Zephyr RTOS, NuttX, Yocto Linux
- Full custom PCB design, RF, SMT prototyping lab (0402/BGA), VNA testing
Example projects I can build for you today
- Smart guardian AI: monitors 40+ sensors 24/7, speaks audible warnings, auto-actuates ventilation/doors, notifies owners instantly.
- Industrial predictive-maintenance agent that predicts failures days ahead and verbally guides technicians.
- Autonomous robots (ground/ocean) with LLM high-level planner that explain their decisions out loud.
- Autonomous AI chatbot with real-time environmental awareness via custom sensors, private document RAG, persistent user memory, tool-calling actions, and natural spoken alerts.
Monthly retainer: €8 000 | Fixed-price projects welcome | Feasibility studies + PDF report available
