SmartHealth

SmartHealth is a full-featured telemedicine platform built at Interswitch Group — enabling real-time video and audio consultations between doctors and patients across Nigeria. The system spans appointment scheduling, comprehensive medical records management, an embedded AI chatbot powered by a multi-agent Python service, real-time doctor-patient chat, and a self-hosted telemedicine layer that replaced expensive third-party SDKs.

Konix

Konix removes the biggest barrier to cross-border luxury shopping for African consumers — foreign currency cards. The app lets Nigerian users shop Adidas, Hermès, Nike, and other luxury brands with automatic Naira price conversion, a smart multi-brand cart, WebView storefronts for real brand interactions, and secure payment processing.

FarmSmarter

FarmSmarter brings modern farm management tools to smallholder farmers in remote, off-grid areas of Nigeria. The app works fully offline using Realm, and features custom GPS-powered field boundary mapping with Google Maps polygon drawing — removing the need for expensive external surveying.

What I Build

Two disciplines.
One engineer.

I write the mobile app, the backend, and the AI layer. No hand-offs between specialisms.

Service 01

Mobile Product Engineering

End-to-end React Native apps for real users — offline-first, production-grade, deployed to both stores. I own architecture through App Store review.

  • Offline-first architecture (Realm, SQLite)
  • Real-time video & audio (Stream SDK)
  • GPS + maps integration
  • App Store & Play Store deployment
  • Biometric auth, push notifications
  • CI/CD with GitHub Actions

Service 02

Embedded AI Engineering

I add a conversational intelligence layer to your existing SaaS — your APIs, your auth, your stack. Users act on your platform's data through natural language. Not a chatbot. Not a demo. Production multi-agent systems.

  • Multi-agent orchestration on your existing API
  • Natural language over your platform's data
  • Guard + classify + specialist agent pattern
  • Tool use, function calling, RAG pipelines
  • Embedded in your existing auth & UI
  • Shipped in healthcare and fintech — reference implementations

About

I build the apps
people actually use.

I'm Jeffery Adolor — known as Kizarmie. A full-stack engineer who loves building mobile apps and structuring systems. 4+ years shipping production software across fintech, healthcare, agriculture, and education in Africa.

On the mobile side I specialise in React Native and offline-first architectures — rare, hard-won on low-bandwidth hardware. On the backend I write Node.js and handle the full API and auth layer myself.

My second discipline is embedded AI engineering: I build production multi-agent systems that sit inside existing SaaS platforms and let users act on complex data through natural language — not chatbots, not demos. Shipped in healthcare and fintech.
