Generative AI Development

• Design and implement Generative AI solutions, including:
  • RAG (Retrieval-Augmented Generation) pipelines Build end-to-end systems integrating vector databases (e.g., Pinecone, Weaviate, FAISS), embedding models, and LLMs to enable context-aware, knowledge-grounded responses
  • Prompt engineering and optimization Develop robust prompting strategies, templates, and workflows that maximize LLM performance, accuracy, and consistency
  • LLM fine-tuning and reinforcement learning Customize foundation models using supervised fine-tuning (SFT), reinforcement learning from human feedback (RLHF), or parameter-efficient methods (LoRA, QLoRA) to improve performance for domain-specific tasks
  • Model evaluation and benchmarking Establish rigorous evaluation frameworks to measure model accuracy, latency, cost, hallucination rates, and task-specific performance metrics; conduct A/B testing and comparative analysis across models and configurations
  • Observability and monitoring Implement comprehensive logging, tracing, and alerting systems to track model behavior, prompt-response patterns, token usage, errors, and drift in production environments
• Build production-grade AI agents using both low-code platforms and high-code custom implementations, optimizing flexibility, performance, and maintainability
• Integrate diverse AI/ML capabilities including natural language processing (NLP), computer vision, document intelligence, and traditional machine learning models as needed to solve complex business problems
• Stay current with the rapidly evolving AI landscape, evaluating and adopting new models, techniques, and tools to continuously enhance solution capabilities and maintain competitive advantage
