Work with me

From idea to production, with one person.

Backend, web, mobile, AI and infrastructure in one pair of hands. I pick the technology to fit the product, and from the first call to launch you work with me.

How we work together.

You always know where things stand.

  1. 1

    Discovery

    We pin down the product, scope and architecture together, and decide what comes first.

  2. 2

    Build

    I build the backend, web, mobile and integrations. You follow progress through working versions.

  3. 3

    Ship

    I set up production, the CI/CD pipeline and deployment, so the product goes live safely.

  4. 4

    Iterate

    After launch, we keep growing the product with maintenance and new features.

Common questions.

What kind of projects do you take on?
Web applications, mobile apps, backends and APIs, and AI features inside real products. I can own the whole product or the part you need.
How are cost and timeline decided?
They depend on the scope. In our first conversation we clarify what needs to be built; then I send you a written proposal with the scope, the plan and the cost.
Can you join a product that already exists?
Yes. I start by reading the code and the architecture, then we agree on what to improve or build next.
What happens after launch?
We can keep growing the product with maintenance and new features. I set up the deployment pipeline, so shipping updates stays routine.
Which languages do you work in?
Turkish and English, in writing and in meetings.

Available for selected freelance projects

Tell me about your product.

A few sentences are enough: what you want to build, who it is for, and where things stand today.
