Alina M.

Hi there! I'm an AI Engineer specializing in Computer Vision, LLM Fine-Tuning, RAG Systems, and AI Agent Development. With 4+ years of hands-on experience in Machine Learning and AI engineering, I build intelligent, production-ready systems that help businesses automate workflows, analyze visual data, detect sensitive information, and make smarter decisions with AI. ⚙️ What I Do: • RAG & LLM Systems: Production RAG pipelines with semantic search, vector stores (ChromaDB), time-aware retrieval, and grounded LLM responses via OpenAI GPT-4o-mini and LangChain — deployed on GCP with Docker and GitLab CI/CD • LLM Fine-Tuning: End-to-end fine-tuning pipelines across Llama, Mistral, Gemma, Phi, DeepSeek, Qwen, and Granite for NLP classification tasks — including custom dataset construction, HuggingFace Trainer API, and benchmark evaluation • Computer Vision: Real-time object detection and tracking (YOLOv8/v11, ByteTrack, StrongSORT), multi-camera Re-ID with epipolar geometry, emotion recognition, and TensorRT/ONNX-optimized inference pipelines • AI Agents & Automation: LLM-powered agents, Celery-based data ingestion pipelines, chatbot development, and API-driven workflow automation with FastAPI • ML Model Development: CNNs, NLP, model training, fine-tuning, ONNX/TensorRT optimization, and scalable production deployment • AI Infrastructure: FastAPI, Docker, GCP, GitLab CI/CD, PostgreSQL, MongoDB, Redis, scalable AI app architecture 🧠 Tech Stack: Python · PyTorch · HuggingFace Transformers · LangChain · OpenCV · YOLOv8/v11 · ChromaDB · FastAPI · Celery · Docker · PostgreSQL · MongoDB · GCP · GitLab CI/CD · ONNX · TensorRT · Streamlit · Stable Diffusion · scikit-learn 🌟 Why Clients Work With Me: • End-to-end delivery — from data collection and model training to production deployment and maintenance • Hands-on experience across media, retail, urban planning, and data privacy domains • High focus on accuracy, low latency, and scalability • Clear communication, fast delivery, and strong problem-solving under real production constraints Let's bring your AI, Computer Vision, or LLM idea to life 🚀
