About Me

I’m Friday Onojah, a Full-Stack & AI Engineer focused on building scalable, user-friendly digital products. I move seamlessly across the ecosystem, from designing responsive frontend interfaces in React and TypeScript to architecting secure, asynchronous backend systems using Python (FastAPI, Django) and Node.js.

My AI work centers on LLM frameworks like LangChain to integrate generative capabilities into real-world SaaS products, supported by robust database engineering, third-party API integrations, and cloud-native deployments.
