Custom Web Software Development
I build custom web software that fits the way your business actually works: customer portals, admin panels, booking systems and multi-sided marketplaces. As a freelance full-stack developer in İzmir, Turkey, I design the architecture, write the backend and frontend, and stay with the product long after launch.

My Working Process
- 01 step Analysis I map your workflows, user roles and data, and turn them into a clear scope for the first version of the product.
- 02 step Architecture I choose the right stack and design the data model, modules and integrations so the system can grow without rewrites.
- 03 step Iterative Development Features are delivered in short cycles on a staging environment, so you can review real progress and steer priorities.
- 04 step Testing & Launch Automated tests, performance checks and a controlled deployment with Docker and CI/CD bring the application to production.
- 05 step Support & Evolution After launch I monitor the system, fix issues quickly and keep extending the software as your business needs change.

05Why
Why Custom Web Software?
Fits Your Process
Instead of adapting your business to a generic tool, the software follows your exact workflows, rules and terminology.
You Own It
The code and data belong to you. No per-seat licence fees and no dependency on a vendor's roadmap or pricing changes.
Grows with You
A clean, modular architecture makes it straightforward to add features, integrations or a mobile app later on.
Competitive Advantage
Software built around what makes your business different can become a real edge that competitors cannot simply buy.
How much does custom web software cost?
It depends on the scope: the number of modules, user roles, integrations and how complex the business rules are. After an analysis meeting I prepare a detailed proposal broken down by feature. Contact me to get a quote for your project.
Which technologies do you use?
On the backend I mainly use Laravel and NestJS with PostgreSQL or MySQL, Redis and queues such as RabbitMQ. On the frontend I use React, Next.js or Inertia.js with TypeScript and Tailwind CSS. The final choice depends on your project's needs.
What is the difference between SPA and SSR, and which do I need?
A single-page application feels fast and app-like, which suits dashboards and panels behind a login. Server-side rendering delivers ready HTML to search engines, which matters for public pages that need to rank. Many projects combine both, and I recommend the right mix during analysis.
Can the same system also power a mobile app?
Yes. I design the backend with a documented API from the start, so a React Native app can use the same data and business logic. Extracım is a good example: one Laravel codebase serves the web app, the mobile API and the admin panel.
Can you take over or modernise an existing project?
Yes. I start with a code and architecture review, then propose a step-by-step plan, from quick fixes to a gradual migration. The goal is to improve the system without stopping your business.
Who owns the source code?
You do. The code is kept in your repository and the servers run under your accounts, so you are never locked in. I also provide documentation so another developer could continue the work if needed.
Do you work with clients outside İzmir?
Yes. I am based in İzmir, Turkey, and work remotely with clients across Türkiye and abroad, including ArtXSpace in Miami and OneBill in Ireland. We communicate through regular calls and a shared staging environment.
07Guide
Off-the-shelf tools are great until your business outgrows them. When your workflows, pricing rules or user roles no longer fit a generic product, custom web software becomes the better investment. With more than 15 years of experience, 100+ projects and 30+ clients, I build web applications that are designed around how your business really works.
What I Build
Most of my web projects fall into a few categories, often combined in a single product:
- Marketplaces that connect two sides, such as businesses and staff, or buyers and suppliers
- Booking and ticketing systems with availability, QR verification and payments
- Customer portals and city guides with search, maps and rich content
- Admin panels and back offices for managing content, users, orders and reports
- B2B platforms with requests, bids and approval flows
Real Projects
Extracım is an on-demand staffing marketplace for restaurants, hotels and events. Businesses post listings and negotiate through offer and counter-offer chains, while staff manage availability, messages, reviews and payments. A single Laravel codebase powers the Inertia web app, a 160+ endpoint API for mobile and the admin back office.
İyi Masa is a restaurant discovery and discounted reservation platform where every booking also funds a social cause. It includes availability-based booking, QR-verified reservations, Google and Apple sign-in, and city and district landing pages with generated sitemaps for search visibility. İzmir Mekan Rehberi, the city's venue and events guide, adds AI-assisted natural-language search, Google Maps and structured data for rich results.
What these projects have in common is that the business logic is the product. Offer chains, availability rules, verification steps and approval flows are modelled carefully in the domain layer, so they can be tested, changed and extended without breaking the rest of the system.
A Modern, Reliable Stack
On the backend I work mainly with Laravel and NestJS, backed by PostgreSQL or MySQL, Redis caching and RabbitMQ or Laravel queues for background jobs. For search I use Meilisearch or Elasticsearch, and for real-time features Reverb and WebSockets. On the frontend I use React, Next.js and Inertia.js with TypeScript and Tailwind CSS, choosing between a single-page app and server-side rendering depending on whether a page lives behind a login or needs to rank on Google.
I follow Clean Architecture, DDD and SOLID principles and write automated tests with Pest and PHPUnit, so the codebase stays understandable and safe to change years after launch. Deployments run on Docker and Nginx with CI/CD pipelines on GitHub Actions.
How We Work Together
We start with an analysis of your workflows and users, then agree on a focused first version. I develop in short iterations on a staging environment so you can see real progress every week and adjust priorities. After launch I stay involved with monitoring, fixes and new features.
I am based in İzmir and work with clients across Türkiye and abroad. If you have a process that deserves better software, let's talk about it.
