Hi Contra , a big part of my work is building ML projects end to end, from exploration to deployment. I work across the full lifecycle: • 🔍 EDA & data validation on large, messy datasets • 🧩 Feature engineering with PySpark driven by business logic • 🧠 Model training & evaluation (time-series & ML) • 🚀 Production pipelines & deployment On the engineering side, I focus on making ML reliable and scalable: • PySpark pipelines for feature engineering, batch training & inference • MLflow for experiment tracking, model versioning & reproducibility I enjoy working with teams that care about clean ML systems, not just experiments , especially when models need to be trusted and reused. 👉 If you’re looking for someone to build ML pipelines end to end , from data exploration to production I’m open to contract or freelance work.

👋 Hi Contra — I’m Lilya, a Data Scientist working at the intersection of retail, demand forecasting, and promotion analytics. My recent work focuses on SKU-level forecasting, where small modeling choices have a big business impact: • 📦 Improving SKU-level demand forecasts for planning & inventory • 📊 Approximating the pull-forward effect of promotions On the technical side, I work end-to-end: • Time-series & ML forecasting • Promo, price & calendar feature engineering • PySpark batch pipelines & MLflow tracking 💡 Open to freelance or contract projects around demand planning, retail analytics. Happy to connect 🚀

🧠 Hi Contra, alongside retail forecasting, I’ve worked on applied NLP and computer vision projects that go beyond experiments and turn into real solutions. I’ve built: • Review rating prediction with BERT • Text summarization using FLAN-T5 • Sign language classification • Fruit disease detection with Fast R-CNN • A neural-network chess move predictor What I enjoy most is shaping messy data, choosing the right models, and evaluating solutions realistically. 👉 If you’re building NLP or computer vision products and need someone hands-on, I’d love to connect.

🤖 Hi another side of my work is building LLM-powered systems that actually ship. I’ve worked on chatbots and AI assistants from research to production, focusing on usefulness and reliability: • Designing LLM-based recommenders using LangChain & FAISS • Fine-tuning transformer models (BERT, T5 / FLAN-T5) for real NLP tasks • Testing, debugging, and improving chatbot behavior based on user feedback ⚙️ Tech I often use: PyTorch, Hugging Face, LangChain, vector search, MLflow 💡 Open to freelance or contract work where teams need: • LLM integration or fine-tuning • Chatbots or AI assistants that deliver real value • Practical NLP solutions, not demos Happy to connect with teams building AI-driven products 🚀
