How I work

  1. Intro and scope

    I listen to what you want to build and we write down the need, the constraints and what success looks like.

  2. Plan and estimate

    I split the work into small deliverable pieces; each has an estimate and a priority from the start.

  3. Build and regular demos

    The code lives in your repository from day one; every week I show a working version and we steer with your feedback.

  4. Handover and support

    I deliver with documentation, setup and a handover call, and stay reachable for fixes and small improvements after launch.

Ways to work together

01

On-site

At the office in Istanbul or Tekirdağ, alongside the team. For work that needs day-to-day communication and quick decisions.

02

Hybrid

Part of the week at the office in Istanbul or Tekirdağ, the rest remote. I keep office days for planning, meetings and working with the team.

03

Remote

I work with teams in other time zones through written communication, regular demos and a task board everyone can see.

04

Freelance and project-based

Well-scoped work: an API, a web app, an integration or help on an existing project. Scope and delivery date are agreed before we start.
