Andrey Plotnikov

AI/LLM Engineer | RAG & Intelligent Agents Developer | Voice Bot Specialist

Passionate AI developer specializing in Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and intelligent agent systems. I build cutting-edge AI solutions—from smart assistants to voice-enabled bots—that leverage natural language understanding, contextual reasoning, and seamless data integration. With expertise in Python, C++, C#, Dart, and robust database management (PostgreSQL, MySQL, MSSQL), I deliver scalable, efficient AI applications tailored to your business needs.

Core Expertise:

🔹 AI Agent & RAG Development:

• Design and deploy custom LLM-powered agents for automation, decision support, and dynamic user interactions.
• Implement RAG pipelines to enhance model accuracy with real-time data retrieval from structured/unstructured sources.
• Build context-aware assistants (e.g., customer support bots, research tools) using frameworks like LangChain, LlamaIndex, or custom Python stacks.

🔹 Voice & Conversational AI:

• Develop voice-controlled bots integrating speech recognition (e.g., Whisper, Google ASR) and synthesis for hands-free user experiences.
• Architect multimodal assistants combining text, voice, and API-driven workflows.

🔹 Full-Stack AI Engineering:

• Languages: Python (PyTorch, TensorFlow, Transformers), C++ (performance optimization), C# (.NET integrations), Dart (Flutter for cross-platform UI).
• Databases: PostgreSQL, MySQL, MSSQL – skilled in optimizing queries, vector storage (pgvector), and data pipelines for AI training/inference.
• LLM Tools: Fine-tuning (LoRA, QLoRA), prompt engineering, OpenAI API, Llama 2, Mistral, and open-source model deployment.

What I Deliver:

✅ End-to-end AI solutions: From concept design to deployment, including API integration and cloud hosting (AWS/Azure/GCP).

✅ High-performance agents: Systems that handle complex workflows, data analysis, and user intent detection.

✅ Secure, scalable architecture: Emphasis on privacy, low-latency responses, and database efficiency.
