About Me

I have almost 6 years of experience in UI/UX Design; I design 5 mobile apps for IOS and Android which some of them from scratch and some of them are re-design. Besides that, I involved in many multi-platform projects; responsive websites, desktop apps and UX audit with design teams in IT companies. It is very valuable for me to contribute to products that make life easier for people and learned that it’s only possible with good UX.

What about my background?
I was educated well in computer graphics, software development and designing educational materials based on computer technologies at Marmara University (Istanbul) in 2012. Studying Computer Graphics lead me to develop a real affinity for UI Design, hence following my degree, I decided to peruse a field I am genuinely passionate about, which is why I am a UI/UX designer and not a Teacher or Developer. To sharpen my UX skills, I conducted usability lab studies to compare two and three-dimensional UI designs in VR environments in terms of usability for my Master's thesis.

I am a social person and love technology. So, I attend to the local UI/UX Design, VirtualReality meetups which provides me with an opportunity to both network, share and develop my own knowledge. In my personal life, I love spending time in nature, doing sports -pilates, tennis or volleyball-, cooking and discovering good restaurants in multicultural Berlin.

The Design Approach

My approach usually starts with examining the project within 2 phases of UXPA(User Experience Professionals Association)’s UX/UCD (User-Centered Design) process which also fits the HCD (Human-centered design) process.

Analysis Phase

I usually follow these steps in the analysis phase to clarify the project outline.

  • Field studies  and research
  • Clarify the context:
  • Goals/needs
  • Assumptions
  • Problems
  • Constraints
  • Competitor audit & product inspiration
  • Develop task analysis
  • Document user scenarios

Design Phase

I usually follow these steps in the design phase to keep the balance between user's and stakeholder's needs.

  • Brainstorm design concepts
  • Develop screen flow
  • Create low-fidelity wireframes
  • Create low-fidelity prototypes
  • Conduct usability testing
  • Create high-fidelity detailed design
  • Conduct usability testing
  • Do improvements on final design
  • Document standards and guidelines
