Clinton Njoku

I am an AI/ML Engineer and Prompt Engineer with 6 years of experience across machine learning, prompt engineering and AI systems development. I turn business requirements into practical AI solutions using Python, LLMs, Generative AI, machine learning, and OpenAI APIs.

I design and optimise system prompts, few-shot prompts, structured outputs, guardrails and conversational workflows to improve the quality and reliability of AI-generated responses. My prompt engineering work has improved AI output consistency by approximately 35%, while AI-assisted workflows have helped reduce project delivery time by 30%.

My portfolio includes DataBot, a conversational AI assistant for Data Scientists; ServiceBot, a context-aware customer service chatbot; and OptimBot, an AI career coaching assistant for data and AI professionals. These projects have strengthened my experience in LLM application development, prompt evaluation, conversational AI and AI system optimisation.
