HREdition is a subscription-based human resources management application owned by KoçSistem.

I worked on the project for two years. The application includes onboarding, personnel management, absence management, ability management, performance management, payroll management modules, and reporting sub-modules. It is a multitenant application that is based on multitenant software architecture.

I built the application from scratch with my team. It is the application that I've taken the most responsibility for in my career. I was involved in all parts of the development process, beginning with system design and delivering the application to production. I have implemented the project's multitenant architecture and developed performance management, organization management, and online payment modules.

The performance module was based on KPI. The organization management module could show the organization tree at any time in history. I implemented the online payment module with iyzico payment system and the hangfire jobs to process periodic payments. Tenants can purchase any module, and every module has its price.

DSS is a sales system that includes CRM and customer integration for FordOtosan, an automotive manufacturing company based in Turkey that Ford Motor Company and Koç Holding own equally.

The project manages transactions for customer orders, dealer orders, and sales invoices. I worked on DSS for more than three years. I worked on an old project built on ASP.NET Web Forms and Oracle - PL/SQL in the first year. I supported the bugs and developed the required new modules. I created DSS using the ASP.NET MVC framework from scratch and supported the old project.

Goferium was my term project at BSC, a real-time strategy game.

I developed Goferium by using the Unity3D game engine. The main challenge of the project was to build gameplay and implement strategic AI for computer playing. I implemented computer graphics algorithms like Hermite Spline Curves for object movements, graph algorithms like A* Search for pathfinding, and Decision Tree for individual AI.
