I'm an Gen AI Engineer and Software Engineering student passionate about building intelligent systems that actually work in production. I specialize in the full AI engineering stack, from designing LLM-powered pipelines to deploying multi-agent systems. My core toolkit spans Python, LangChain, LangGraph, OpenAI API, HuggingFace Transformers, Pinecone, FAISS, and RAG architecture. I work with agentic frameworks including CrewAI and AutoGen, and I'm experienced in prompt engineering, vector database design, and LLM fine-tuning workflows. On the software engineering side, I bring solid full-stack depth — React, Next.js, FastAPI, Node.js, TypeScript, REST APIs, and SQL/NoSQL databases. I've worked across the stack in Java, Python, JavaScript, and C#, with a strong foundation in object-oriented design, system architecture, and version control with Git. Beyond the code, I think carefully about how AI systems are structured — memory management, tool use, orchestration, observability — because building agents that are reliable matters more than building agents that are impressive. Currently in my final year of BSc (Hons) Software Engineering at Cardiff Metropolitan University, enrolled in the STEMLink AI Engineer Bootcamp, and publishing technical content under my personal brand Amiru AI Lab and GitHub and Medium. Always open to AI engineering internships, collaborations, and conversations about what's next in the space.
