About
I’m Ruth Ndunge Muthui, a Senior Software Engineer with 7+ years of experience building scalable full-stack and AI-powered applications, especially in digital health, education, and user-focused platforms. I work across the product lifecycle—from defining requirements with stakeholders to architecting, implementing, and shipping reliable systems in the cloud.
I specialize in building modern web applications with TypeScript/JavaScript and frameworks like Angular, React, and Next.js, alongside backend services in Node.js and MEAN-stack architectures. I also integrate LLM-based conversational experiences using techniques like RAG and semantic retrieval, and I’ve led engineering delivery as a team lead, improving performance, SEO, and user workflows while maintaining strong engineering practices like code reviews, CI/CD, and testing.
