👋 Hi, I'm Niyonkuru Bertin

🚀 Full Stack Developer | Backend-Focused | Systems Builder
📍 Kigali, Rwanda

I design and build scalable, real-world systems — from pharmacy inventory platforms to multi-tenant SaaS products — with a strong focus on performance, simplicity, and maintainability.

I don't just write code — I build products that work in real environments.

🧠 What I Do

  • Architect scalable backend systems (Node.js, PostgreSQL, Prisma)
  • Build multi-tenant SaaS platforms with RBAC & clean data isolation
  • Design real-world business systems (pharmacy, school, survey platforms)
  • Implement event-driven architectures using Kafka
  • Deliver clean frontend experiences with React + Tailwind
  • Focus on production-ready systems, not just demos

🏗️ Current Focus

  • 💊 TangaCare — Pharmacy Inventory & POS System
    → Multi-location, FEFO, WAC, EBM (RRA compliance)
  • 🏫 Smart School Rwanda
    → Multi-tenant school system with RBAC & academic workflows
  • 📊 AskField (Survey Platform)
    → Replacing Supabase with a fully custom backend
