About Anshu Kumar

I like solving messy, real-world problems with ML, especially when the output becomes a tool that people rely on. Over the last 3.5 years, I’ve worked across data pipelines, modeling, and deployment. At Nokia, I automated ETL for 50k+ daily telecom KPI records and built a Network Quality Scoring Engine using 52+ KPIs. It was adopted by 30+ engineers and helped reduce triage time by ~85%.My stack includes Python, SQL (BigQuery), GCP, scikit-learn, LangChain/FAISS for RAG, and deployment using FastAPI/Flask, Docker, and Streamlit.If you’re hiring for DS/ML/GenAI roles and think my experience fits, feel free to connect or message me.(Email: a••••••••@gmail.com)
