Medical student. AI engineer. Builder from Nigeria.
I ship SaaS products, retrieval systems, agentic voice products, and Web3 infrastructure — often aimed at problems I've watched go unsolved in African healthcare and global developer tooling.
I build at the intersection of AI, medicine, and decentralized systems. Medical school taught me to read pathology; a decade of tinkering taught me to ship. The two meet in the work I do: retrieval systems that reason instead of chunk, voice-first agents that triage real patients, desktop research tools for systematic reviews, and on-chain primitives for things that need to be trustless.
Most of what I finish starts as a friction point I've personally watched break down — hospital payment queues, PubMed synthesis, agent memory across sessions — and ends as a product someone else can use today.

Things shipped as real npm / PyPI packages with CI and live users.
| Project | What it does |
|---|---|
| vectorless | Structure-preserving document retrieval. TS + Python SDKs on npm + PyPI. Next.js + Fastify. |
| context8 | Collective memory for coding agents — stores solved errors in a vector DB so agents can retrieve fixes via MCP. Built on Actian VectorAI DB. (PyPI) |
| tytube | TypeScript port of pytube: YouTube metadata, streams, captions — no API key. Node / Bun / browser. (npm, signed) |
| youtube-transcript-ts | TypeScript port of youtube-transcript-api with translation + multi-format. (npm) |
| yarngpt-sdk | Unofficial Python SDK for YarnGPT's Nigerian-accent TTS — 16 voices, async + CLI. (PyPI) |
| swarmtorch ⭐ | PyTorch library of 120 metaheuristic optimization algorithms (60 training + 60 HPO). GPU-accelerated, drop-in torch.optim.Optimizer. (PyPI, paper in progress) |
| bridgehook | Zero-install ngrok alternative — forwards webhooks to localhost via browser + Cloudflare Worker relay. |
