Web Applications

I develop scalable, fast and secure web applications with modern web technologies: e-commerce, SaaS platforms, corporate portals and custom web software. I build corporate portals, business applications and SEO-friendly corporate websites with Next.js, React and ASP.NET Core, and can deliver a mobile experience without a separate app through installable web apps (PWA) and web push notifications. I can also move applications built with legacy technologies to modern web architectures. As a freelance software developer in İzmir, Türkiye, I work online with businesses in İzmir and the surrounding region, delivering in regular increments so you can follow progress. For live examples, see Türkiye Gezi Rehberi, Karadeniz Turu and my industry demo sites.

Frequently asked questions

Off-the-shelf package or custom software?

For a standard business website or a common business process, ready-made solutions may be enough. If your processes are unique, you need integration with other systems, or your user and permission structure is complex, custom software is usually more efficient in the long run. In a free initial meeting I listen to your needs and recommend the right path, including a ready-made option if that fits better.

Will my website show up on Google and in AI search?

I build sites on a search-friendly technical foundation: server-side rendering, fast loading, correct title and description tags, structured data (JSON-LD), a sitemap and multilingual structure. This foundation makes it easier for Google and AI assistants to understand your content correctly. Rankings also depend on content and competition, so I do not promise a specific position.

Can a web application work like an app on a phone?

Yes. Applications I build as Progressive Web Apps (PWA) can be installed on the phone's home screen and can send instant web push notifications. Comprehensive business applications can be built this way too. If app store presence or deep access to device hardware is required, I evaluate a native mobile app with you.

Can you rebuild my old web application?

Yes. I move web applications built on legacy technologies to modern architectures such as ASP.NET Core, Blazor and Next.js. I first document the existing screens and business rules, then migrate modules one by one. Users keep working throughout the transition and your existing data is carried over to the new platform.

Do you provide support after launch?

Yes. After launch I provide support for bug fixes, security updates, content changes and new features. I define the scope of support with you based on the project's needs. Because I set up automated release pipelines, new versions are published in a controlled way and, if something goes wrong, the previous version can be restored quickly.
