What I'm Doing

Web Design & Full-Stack Development

I design and build modern, scalable web platforms from the ground up — covering everything from UI/UX and front-end architecture to back-end APIs and database design. My stack includes HTML5, CSS3/SASS, JavaScript/TypeScript, React, Angular, ASP.NET Core, and modern CMS platforms like WordPress and Joomla.

I focus on performance, accessibility, and clean architecture — delivering products that are not only beautiful but also fast, secure, and built to scale.

Mobile & Cross-Platform Applications

I develop mobile solutions for iOS and Android using Xamarin, .NET MAUI, and native integrations. My experience covers m-commerce, secure payment flows, and real-time data synchronization across devices.

I also integrate emerging technologies such as IoT, push notifications, and decentralized payment options to deliver modern, future-ready mobile experiences.

.NET Development & Architecture

I am a strong believer in the .NET ecosystem and have contributed to over 40 projects across multiple languages and communities. Since 2012, I have been recognized as a Senior .NET Developer, and today I work as a Principal .NET Developer & Staff Software Engineer.

My core focus is on Microsoft technologies — .NET Core / .NET 8+, ASP.NET Core, Entity Framework Core, Microservices, and Clean Architecture — but I also have substantial experience with other stacks such as Node.js, Angular, React, Oracle, and Git. Seminar Info

CRM / ERP Integrations

Most companies deploy ERP and CRM systems separately — which creates constant synchronization problems between databases. I design and implement fully integrated CRM/ERP solutions where both systems share a single source of truth.

The result: real-time data visibility, fewer manual errors, faster reporting, and a significantly lower total cost of ownership for the business.

DevOps & Cloud Consultancy

I help companies accelerate their DevOps transformation through automation, CI/CD pipelines, containerization (Docker, Kubernetes), and Infrastructure-as-Code on Azure and AWS.

From Agile coding and automated testing to deployment and observability, I provide end-to-end consultancy that scales with your team and your product. More Info

Remote Work & Team Leadership

I work comfortably in fully remote environments and have experience leading distributed, remote-first teams. I value clear communication, reliable delivery, and a healthy work-life balance — for myself and for the people I work with.

I consistently deliver 35–40 focused hours per week, and I am equally comfortable managing software development projects and business process improvement initiatives.

Proven Track Record in Türkiye & Globally

In Türkiye, I have designed and delivered end-to-end enterprise applications — from initial architecture and database design to full implementation, deployment, and long-term maintenance. These systems continue to operate and evolve today, serving millions of users across healthcare, telecom, energy, and logistics sectors.

Notable projects include Teleradiology and Hospital Information Management Systems (HIMS) in Türkiye, as well as 5 major international projects delivered for global clients such as Megafon, Vodafone, Heineken, and leading logistics companies.
