Available to hire
I’m John Chibuzor, a full-stack software engineer with 4+ years of experience building production-ready Python/Django systems, REST APIs, and data-driven web applications. Much of my work has supported education, training, and community-focused products—where I help turn real-world requirements into maintainable backend services, role-based admin dashboards, and reliable integrations.
I also enjoy applying AI/LLM APIs to practical features and automation workflows, and I’m hands-on with modern delivery practices like Git-based team collaboration, code reviews, and GitHub Actions CI/CD. Alongside my engineering work, I currently facilitate Enterprise Python training for 500+ students in a government-sponsored program and I’m completing my B.Sc. in Cyber Security.
