Builder from Nigeria.**\n\nI build production agentic systems with tool use, retrieval, and event-sourced state — across Claude Agent SDK, Vercel AI SDK, OpenAI tools, and VAPI. Three shipped in 2026 — Video Studio, AuraHealth, NotebookLM-clone — and the open-source retrieval substrate underneath them.\n\n[![Vectorless](https://img.shields.io/badge/Launching-vectorless.store-black?style=flat-square)](https://vectorless.store)\n[![Location](https://img.shields.io/badge/📍-Nigeria-008751?style=flat-square)]()\n[![Open to work](https://img.shields.io/badge/Open%20to-Contracts%20%7C%20AI%20Engineering%20%7C%20Research-brightgreen?style=flat-square)]()\n[![Followers](https://img.shields.io/github/followers/hallelx2?style=flat-square\u0026label=Follow\u0026color=blue)](https://github.com/hallelx2)\n\n\u003c/div\u003e\n\n---\n\n### About\n\nI build agentic systems that do real work in production. Tool use, retrieval, approval gates, real users — across whichever runtime the product needs (Claude Agent SDK, Vercel AI SDK, OpenAI tools, VAPI, MCP). Underneath sits the retrieval layer I open-source as **Vectorless** — structure-preserving document retrieval, no chunking, no top-K, no vector DB.\n\nMost of what I finish starts as a friction point I have personally watched break down — hospital payment queues, document retrieval, agent memory across sessions — and ends as a product someone else can use today. I am also a medical student, which is why a lot of the harder problems on this page live somewhere near a hospital.\n\n**Available for contract work** in agentic systems, RAG / retrieval engineering, and applied healthcare AI.\n\n---\n\n### 🚀 Live Products\n\n| Product | What it does | Link |\n|---|---|---|\n| **Vectorless** | Document retrieval for the reasoning era — LLMs navigate document maps instead of vector chunks.
