02 / About
Engineer who builds it, and tests it like it's going to fail.
I'm Nuru Abimana, a software and QA engineer based in Kigali. For five years I've worked on the systems Rwandans use every day: mobile money and card payments, internet and mobile banking, farmer registration and input orders, and government e-services.
On the build side, I design and ship web and mobile products with Next.js, FastAPI, Flutter and PostgreSQL, from architecture to app-store release. On the quality side, I build Playwright/TypeScript test automation for UI, backend and API layers and run it in CI/CD on every push.
Doing both means I catch problems early: I review requirements before code is written, test at the API and data layers, and trace bugs into the code with the team instead of just reporting the symptom.
What I do
01
Web & backend engineering
Next.js and TypeScript front ends, FastAPI and NestJS services, PostgreSQL and Supabase, multi-tenant access control and payment integrations.
02
Mobile apps
Flutter apps for iOS and Android, from first build to Play Store and App Store release, with push notifications and CI/CD.
03
Quality & test automation
Playwright frameworks for UI, backend and API; k6 load testing; CI/CD quality gates; defect tracking in Jira and BrowserStack; Allure dashboards.

How I think
Systems fail for predictable reasons.
Poor assumptions about scale
Weak handling of edge cases
Lack of observability
Rushed architecture decisions
Avoiding these is not about writing more code. It's about designing systems with reality in mind from the start.
