## What I'm looking for

```text
I'm available immediately and open to remote roles across Europe, the UK, and the Middle East time zones, as well as hybrid or on-site roles in İzmir.
```

## About

```text
At Creaware, I led a cross-functional team of up to 15 engineers while staying hands-on with architecture and code. I architected payment orchestration across iyzico, PayTR, Stripe, and partner gateways, and built .NET Core services for ERP integrations.

I also built Twilio SMS and WhatsApp messaging for four countries and automated tenant provisioning through the Coolify API, reducing setup to a single click. Introducing AI-assisted development cut PR cycle time by about 35%.

At K2M, I designed an internal stock and order management system using Clean/Onion Architecture and CQRS. I added Redis caching to a call-detail-record system processing more than two million records per day, making its real-time panel usable.

Earlier, I built .NET Core ERP and marketplace integrations at Projen Yazılım and production applications at Dokuz Eylül University. In a personal Azure project, I deployed cloud operations automation with AI alert triage and a RAG runbook assistant.
