# Shiva Lakumarapu > AI Engineer | Generative AI & LLM Systems | Prompt Engineering | NLP | LangChain | Hugging Face | AWS SageMaker | PyTorch | GPT-4 Location: Irving, Texas, United States Profile: https://flows.cv/shivalakumarapu I’m an AI/ML Engineer specializing in Generative AI, LLM systems, and intelligent automation. Over the past 5+ years, I’ve designed and deployed large-scale machine learning and NLP solutions across finance, healthcare, and insurance — building everything from RAG-based knowledge assistants to transformer-powered compliance systems. At Gilead Sciences, I develop LLM applications using GPT-4, BERT, and LangChain, integrating them with FAISS and pgvector for semantic retrieval and contextual grounding. My focus is on building production-ready GenAI pipelines with strong MLOps foundations using AWS SageMaker, MLflow, and Docker/Kubernetes. I’m passionate about prompt engineering, multimodal AI, and explainable ML, ensuring every model I ship is interpretable, scalable, and business-ready. ⚙️ Core Skills: GPT-4 | LangChain | Prompt Engineering | RAG | Hugging Face | PyTorch | TensorFlow | AWS SageMaker | FastAPI | MLflow | NLP | Computer Vision | Docker | Kubernetes 📚 Recent focus: LLM-based document summarization, multimodal report generation, and generative AI observability. ## Work Experience ### Gen AI Developer @ Gilead Sciences Jan 2024 – Present | Dallas, Texas, United States Designing and deploying Generative AI systems using GPT-4, BERT, and LangChain for summarization, content generation, and conversational intelligence.
