02 / THE APPROACHBUILD → CONNECT → SHIP

Engineering from
interface to
infrastructure.

I like owning the path from an idea to a working product.

A feature is more than its screen. It needs a clear data flow, a useful API, and a way to reach the people it was built for.

At work, I build across frontend and backend. With Pinliyo and BoxOS, I also make the product decisions: what to build, how it should feel, and when it is ready to ship.

01 /

Build↗

Backend systems, APIs, and application architecture.

02 /

Connect↗

Interfaces, state, integrations, and data flow.

03 /

Ship↗

Deployment, production concerns, and finished products.

03 / MY WORK AT ALLIANZ TÜRKİYESOFTWARE DEVELOPER

From the screen
to the service
behind it.

I develop web interfaces with Angular and backend services with Spring Boot at Allianz Türkiye.

That means working across what people see, the requests an application makes, and the integrations that connect it to other systems.

01 / FRONTEND

Make the next action clear.

Interfaces and application state that keep the screen in step with what the system is doing.

02 / BACKEND

Make the contract explicit.

Services, API design, and integrations that keep data moving between applications.

03 / DELIVERY

Think beyond the feature.

Maintainability, deployment, and runtime concerns that matter after the code is written.

04 / CAPABILITIESTOOLS FOLLOW THE PROBLEM

What I reach for.
What I use it for.

Turn a requirement into a working interface and a clear service contract.

  • Spring Boot
  • Angular
  • Next.js
  • REST APIs
