Umut in a few words
I speak English | Ik spreek Nederlands | Ben Tรผrkรงe konuลŸuyorum

As a Senior Software Engineer with a passion for clean architecture and scalable solutions, I bring over a decade of experience in designing, developing, and delivering high-quality software across diverse industries, including Telecom, CRM, Real Estate, Pharmacy and Cleaning.
Iโ€™m also fluent in Dutch, English, and Turkish, allowing me to navigate multicultural environments and communicate effectively.
Thanks to proficiency in .NET development, both on the backend (Core, Web, Desktop/Framework) and the frontend (WPF, HTML, CSS, JavaScript, Angular, ExtJS, Vue.js), Iโ€™m committed to building robust and maintainable systems. Besides .NET I'm also experienced in Java/Kotlin for mobile or desktop development.

My technical expertise includes:
- In-depth understanding of clean code, SOLID principles, and clean architecture
- Proficiency in CI/CD tools such as Azure DevOps, GitHub, Jenkins, and Pipelines
- Strong knowledge of NoSQL, SQL, and Entity Framework
- Experience with message brokers like Azure Service Bus, RabbitMQ, and Kafka
- Advanced skills in building REST APIs and containerization using Docker and Kubernetes (Azure AKS)
- Expertise in architectural concepts: Microservices, TDD, DDD, CQRS, DNS, Load Balancing, GSLB, CAP Theorem, API Gateway, and Lambda Architecture
- Skilled in writing effective Unit Tests (xUnit) and leading teams toward high-quality software delivery

Throughout my career, Iโ€™ve worked in various sectors, giving me a well-rounded understanding of industry-specific challenges and solutions. Beyond technical expertise, I'm passionate about solving complex problems, mentoring colleagues, and continuously evolving as a leader.
