Partner with business, product, and engineering stakeholders to design and implement enterprise-scale AI solutions, with a strong emphasis on Generative AI applications (LLMs, multimodal, agentic AI).

Define and own the AI/ML roadmap for key problem areas, balancing near-term delivery with long-term innovation.

Lead design, prototyping, and deployment of Generative AI models (GPT, Claude, LLaMA, Mistral, Stable Diffusion) for production use cases.

Build and optimize data pipelines, retrieval-augmented generation (RAG) systems, embedding strategies, and integrations with vector databases (FAISS, Pinecone, Weaviate, Milvus).

Ensure robust model training, fine-tuning (LoRA, PEFT), orchestration (LangChain, LlamaIndex), monitoring, and governance.

Lead debugging and optimization of AI systems for latency, throughput, cost, and model drift/bias.

Collaborate with ML engineers, data scientists, and MLOps teams to design scalable deployment pipelines using modern cloud and containerized environments.

Mentor and guide engineers, setting best practices for experimentation, evaluation, and production readiness.

Keep abreast of latest AI/ML research in LLMs, CV, NLP, and multimodal learning, driving adoption of cutting-edge methods.

Translate complex AI concepts into business outcomes for non-technical stakeholders.
