I’m John Moses, a senior full-stack AI engineer and co-founding engineer at ShopStack360, where I help build and scale deployed AI systems for commerce in Nigeria. Over the last 10+ years, I’ve architected and shipped across the full stack—backend, web, and mobile—while also designing agentic workflows and LLM-powered products that can operate reliably in production. I enjoy taking models from idea to measurable impact: I’ve built and fine-tuned GPT/transformer models from scratch, created evaluation harnesses and confidence-gated pipelines, and orchestrated multi-agent systems using modern frameworks like LangGraph. I also bring a strong DevOps foundation (Docker, Nginx, AWS) and security-first engineering practices (RBAC, OAuth/JWT scopes), so the AI doesn’t just work in demos—it works safely at scale.…I’m John Moses, a senior full-stack AI engineer and co-founding engineer at ShopStack360, where I help build and scale deployed AI systems for commerce in Nigeria.
