👋 Hi, how are you?
"1% Chance 99% Faith."
— Samwel Ngusa, Machine Learning & AI Engineer
I'm specializing in building intelligent systems and scalable backend solutions. My interest in technology started early, where I enjoyed exploring AI models, machine learning algorithms, and system architectures. This curiosity led me to pursue a career in AI engineering, where I now work on building AI-powered applications, RAG systems, and finetuning LLM models that solve real-world problems.
With experience in AI Agents, document parsing systems, and microservices architecture, I blend technical expertise in machine learning with practical backend development to create intelligent solutions. I've collaborated with cross-functional teams to build AI-powered document processing systems, implement RAG pipelines, and deliver scalable backend APIs that drive business value and innovation.
