About Fancy
AI developer | LLM, AI Agents, RAG Systems, Voice Agents Pro
Nairobi, Kenya - 12:37 pm local time
If you're looking for more than just another chatbot, you're in the right place.
My name is Fancy Chepkoech. I help startups and businesses build intelligent AI applications that don't just answer questions—they reason through problems, automate workflows, retrieve knowledge from complex datasets, and take meaningful actions. My focus is on developing production-ready LLM systems that solve real business challenges, whether that's automating operations, improving customer experiences, or helping teams make better decisions with AI.
Over the past several years, I've worked at the intersection of artificial intelligence, data science, and software engineering. Currently, I work as an LLM Engineer at Amini, where I design and build AI solutions powered by large language models. Before that, I spent more than three years as a Data Scientist at the AI Center of Excellence (AICE), developing machine learning solutions and transforming data into actionable insights. These experiences have given me a strong foundation in both traditional AI and the latest generation of agentic AI systems.
My expertise spans the entire lifecycle of modern AI applications. I build multi-agent systems using LangGraph, CrewAI, LangChain, and AutoGen that can plan, collaborate, and execute complex tasks autonomously. I develop high-performance Retrieval-Augmented Generation (RAG) pipelines using FAISS, Chroma, and Pinecone, combining hybrid search techniques with evaluation frameworks like RAGAS, TruLens, and LangSmith to ensure accuracy and reliability. I also create custom GPT-powered assistants with long-term memory, API integrations, branded interfaces, and workflow automation tailored to each client's business needs.
Beyond development, I focus heavily on deploying AI systems that are reliable and scalable. I build backend services with FastAPI and Flask, containerize applications with Docker, and implement monitoring and evaluation practices that keep AI applications performing well in production. My goal is always to deliver solutions that businesses can confidently rely on—not just impressive demos.
Clients enjoy working with me because I combine strong technical expertise with clear communication. I believe the best AI projects happen when technical complexity is translated into practical business outcomes. I keep clients informed throughout the process, explain technical decisions in plain language, and take ownership from initial concept through deployment.
My technical toolkit includes Python, JavaScript, LangChain, LangGraph, CrewAI, AutoGen, OpenAI APIs, Retrieval-Augmented Generation (RAG), FAISS, ChromaDB, Pinecone, FastAPI, Flask, Docker, LangSmith, TruLens, DSPy, Gradio, REST APIs, workflow automation, and LLMOps best practices.
I'm also committed to continuous learning. I earned my Bachelor of Science in Computer Science from Jomo Kenyatta University of Agriculture and Technology (JKUAT) and am currently pursuing a Master of Computer Applications (MCA) at JKUAT (2024–2027, expected), expanding my expertise in advanced computing and AI technologies.
Whether you need an AI agent, an enterprise RAG solution, workflow automation, a custom GPT application, or an end-to-end LLM platform, I can help you build something that's practical, scalable, and delivers measurable value.
I'm currently available for new projects and job invitations. If you're looking for someone who can turn AI ideas into production-ready solutions, I'd be happy to discuss your project and explore how we can build something exceptional together.
