VARDHINEEDI NANDINI

Full-Stack Developer & AI Solutions Engineer

CS + IoT + Cybersecurity engineer who ships production AI systems — not just Jupyter notebooks.

I've built and deployed real backends: a real-time audio topic detection pipeline at BagnDash (US) using FastAPI + MongoDB achieving 75% accuracy and 15% latency reduction, and enterprise-grade RESTful APIs at Koyya Enterprises using Node.js + Firebase with a 30% improvement in data retrieval speed.

My research on an Agentic AI Intrusion Detection System was accepted and published at ICAAAI-2025. On the AI side, I build with RAG pipelines, LangChain, FAISS, LLM integration (Gemini, OpenAI), and prompt engineering — applied to real products. On the full-stack side: React.js, Next.js, Node.js, FastAPI, MongoDB, SQL, CI/CD, and AWS fundamentals.

What sets me apart: 2× hackathon winner (150+ and 100+ team pools), SIH Finalist 2024, 8.65 CGPA, 2,000+ LinkedIn followers, and a CodeChef rating of 1372. Open to SDE, Full-Stack, or AI/ML roles — ideally in product companies where I can own features end-to-end.
