What I'm looking for

I seek roles building production GenAI/NLP systems with ownership of model-to-prod pipelines, collaborative teams, and cloud-native scalable deployments.

I am an AI/ML engineer specializing in building and deploying production-grade Generative AI and agentic systems using LLMs, LangChain, LangGraph, and cloud-native backends. I have delivered RAG pipelines, multi-agent workflows, fine-tuned open-source LLMs, and scalable FastAPI/AWS deployments that improved latency and accuracy for enterprise clients.

I lead small engineering teams, design end-to-end ETL and vector search solutions, and optimize models and retrieval strategies for domain relevance and privacy. My projects include voice-enabled agent platforms, career-guidance agentic systems, secure domain-trained chatbots, and AI text detection models published to Hugging Face and deployed on AWS.
