Arif Kurnaz — Senior Backend Engineer

About Me

16 years. Real systems.
Production consequences.

16+

Years in Production

Not hobby projects. Real enterprise systems under real load, where downtime has a real cost. Backend engineering since 2008.

B2B+
B2C

Both Sides of Scale

Complex B2B integrations connecting enterprise customers, and high-traffic B2C platforms built for spikes. Different problems, same engineering discipline.

End-to-End Delivery

When needed, I own the full stack — DB schema, REST API, Vue.js frontend, PWA, CI/CD. Noticeboard was designed, built and shipped entirely solo.

Born in 1981 in Sivas, Turkey. My interest in software began early and eventually grew into a career.

I started building web applications in 2008 with PHP and MySQL. Over the following decade I went deeper into enterprise territory — B2B integration platforms, high-traffic consumer systems, multi-service architectures with C# and MSSQL. Around 2020 I made the shift to cloud-native: Kubernetes, Helm, Java with Quarkus, proper microservices.

Most recently I built Noticeboard — a multi-tenant PWA for school LCD displays — solo, from database design to Vue.js frontend to Service Worker. It's the kind of project that shows what I can do when I own something end to end.

Career

The path so far

2008

First production systems — PHP & MySQL

Started with web applications and database-driven backends. PHP and MySQL remain part of my core stack to this day.

2010s

Enterprise B2B & B2C — C#, MSSQL, multi-service

Grew into enterprise development — complex B2B integration platforms, high-traffic consumer systems, C# .NET backends, MSSQL at scale.

2025–2026

Keymate.io · Keycloak · Quarkus — Cloud-Native

Worked at Keymate.io — identity and access management with Keycloak, low-footprint Java microservices with Quarkus, container orchestration on Kubernetes.

Feb 2026

Noticeboard — CodeIgniter 4, Vue.js 3, PWA

Built and shipped solo — multi-tenant school LCD display system, modular REST API, Vue.js 3 frontend, Service Worker, 20+ content modules.

Featured Project PWA Solo-built

Noticeboard — School Info Display System

Multi-tenant Progressive Web App built and shipped solo. Administrators manage 20+ content modules through a full dashboard; a Vue.js 3 SPA renders everything in real-time on school LCD screens. Offline-capable via Service Worker, with Excel/RSS/API imports, per-school theming, and a module flag system to minimise unnecessary API calls.
