Freelance Software Developer in İzmir

abcware is the brand I run as a freelance software developer based in İzmir, Türkiye. I build corporate websites, web and mobile apps and custom software, and deliver ERP/CRM and Nebim integration, automation and legacy modernization. I build your project myself from start to finish, with no middleman.

The biggest advantage is that you talk directly to the person building your project: there is no account manager or middleman, so nothing gets lost in translation. Decisions are quick and your questions are answered by someone who knows the technical details. Regular interim deliveries let you follow progress step by step. I handle architecture, integration and security through a simple process suited to small and mid-sized businesses.

Yes. I live in İzmir and my priority is businesses in İzmir and the Aegean region, but because the intro call, interim deliveries, launch and support all happen online, I can also work with businesses in other cities across Türkiye. Meetings take place by video call or in writing, and working versions are shared online, so you can follow the project closely wherever you are.

I work with businesses of different sizes, from local businesses such as restaurants, dental clinics, beauty salons, estate agents, boutique hotels and car services to businesses with production, warehouse and field operations. You can find industry website demos for local businesses, live products in tourism and sample applications in the portfolio. Because I focus on understanding your processes first, we can work out the right solution whatever your industry.

Yes. I can move applications built on legacy desktop and web technologies to modern .NET, web and mobile architectures. I first extract the business rules and data of the existing application, then move modules to the new platform one by one, so your business keeps running throughout the transition.

I mainly use C# / .NET (ASP.NET Core, Blazor, WPF, .NET MAUI), Next.js and React with TypeScript, Node.js and Python (FastAPI). For databases I work with SQL Server, Oracle PL/SQL, MongoDB, Redis and SQLite. I use Git, GitHub Actions and Docker for releases, and have industrial experience with Modbus, MQTT, Zebra ZPL and barcode/QR integrations. I choose technology based on each project's needs.

I build security into the design from the start. Single sign-on with OpenID Connect, one-time passwords (OTP), role-based permissions, bot and brute-force protection on login screens and application hardening are methods I apply. For personal data I design access, logging and retention rules with the Turkish data protection law (KVKK) in mind, and I recommend reviewing the legal side with your legal adviser.

It starts with a free intro call where I listen to your needs, existing systems and goals. I then clarify the scope and prepare a tailored written proposal. During development I work in regular interim deliveries so you can see progress and steer it. After testing and a controlled launch, I continue with maintenance and support. All meetings and deliveries happen online.

Yes. After launch I provide support for bug fixes, security updates, new features and performance improvements. Release pipelines with automated deployment and rollback keep updates controlled. I define the support scope with you based on your project's needs.

Simply fill in the short form on the Get a Quote page describing what you need. I will get back to you and schedule a free online intro call to clarify the scope, your existing systems and your priorities. Because price and timeline depend on scope, I do not quote a fixed figure up front; after the call I prepare a tailored written proposal for you.
