Meet Mariia ✨
An AI/ML Engineer and Back-End Developer with three years of experience delivering advanced AI solutions, automation systems, and data-driven applications. Mariia specializes in integrating large language models and implementing AI-based algorithms for natural language processing, computer vision, and predictive analytics, with a Python-first stack built around FastAPI, LangChain, PyTorch, TensorFlow, and OpenCV.
She has delivered production AI systems across sales intelligence, hospitality security, and marketing automation domains. Her projects include an AI-powered buying committee detection system using LLM prompt chains, PDF parsing, and multi-source data scraping, a real-time computer vision hotel monitoring platform with person detection, tracking, and re-identification across camera views using YOLO, OSNet, and DeepSORT, and an AI social media video automation platform that cleans raw footage and translates it into multiple languages using speech-to-text and text-to-speech AI models.
Mariia works confidently with LangChain, LangGraph, LlamaIndex, Whisper, ElevenLabs, OpenCV, PyTorch, TensorFlow, Scikit-learn, and Streamlit. She builds solid backend infrastructure with FastAPI, SQLAlchemy, Redis, Docker, AWS, and CI/CD via GitHub Actions, and brings automation experience with N8N and Google AppScripts. Her depth in applied AI makes her a standout match for teams building intelligent, real-world AI products.
If you need an AI developer who can architect LLM-powered pipelines, build computer vision systems, and deliver full backend infrastructure for AI-driven products, Mariia brings the expertise to make it happen 🚀

Computer Vision System for Hotel Monitoring
AI Engineer
Project Description:
Developed a real-time AI hotel monitoring system using surveillance cameras to detect, track, and re-identify individuals across multiple camera views. Trained an OSNet model for person re-identification, built the detection and tracking pipeline using YOLO, OSNet, and DeepSORT, configured Docker for real-time video streaming, and implemented a logging and analytics system for guest movement data.
Tools & Technologies:
OpenCV, PyTorch, Torchreid, OSNet, YOLO, DeepSORT, Torchvision, FAISS, Docker
AI Social Media Automatization
Back-End / AI Developer
Project Description:
Built backend services for an AI platform that automates clean video creation and multi-language translation for social media. Implemented backend logic for video upload and processing, integrated OpenAI and Anthropic APIs for prompt engineering and content generation, integrated ElevenLabs for text-to-speech, and added DALL-E and Stable Diffusion image generation. Handled error logging and testing throughout.
