TEB Business and Private Banking

Professional | Teamwork | 2018-2020 | TEB and I-AM Istanbul

During my time at I-AM Istanbul, I was involved in the design processes of both private and business banking platforms for TEB, a prominent Turkish financial institution and a partner of BNP Paribas Group. Collaborating closely with diverse teams, companies and users seeking a smart financial companion, we enhanced online banking experiences by tailoring solutions to their unique needs.

TEB has been serving diverse business customers of varying scales, from multinational businesses to regional SMEs. To exceed its competitors, their internet banking platform required an upgrade. So our focus was transforming TEB's online banking platform into the ultimate choice for business customers seeking a seamless experience. 

Our research findings pointed to the need for “control in managing the finances”, day-to-day and in the long term.

Research Questions

The project explores the following research questions:

  • "How might we simplify the tax payment process?”

  • “How might we get customers to feel supported in managing their cash?”

Exploration & System Analysis

  • Desk Research*
    Netnography and competitor analysis

  • Workshops
    with various business units

* indicates my involvement, as I joined the project during the wireframing phase.

To comprehend business requirements, customers' financial needs and behaviours we conducted

  • Face-to-face  interviews*
    with TEB customers and our stakeholders at TEB

  • Observational Studies*
    with TEB customers


To make sense of the gathered information throughout the exploration phase and understand the system, the following methods had been applied:

  • Proto Persona

  • Affinity Diagramming

  • User Journey Mapping*

Design & Test

The new platform provides full transparency of financial transactions, covering various accounts of various banks, and also the overview of the current status, past and upcoming transactions. Putting AI into work, we designed cash flow forecast notifications that analyse expense and revenue patterns in the past and allow customers to be ready for future challenges and opportunities.

Design & Test

In order to test and deliver the concept, the following methods were used:

  • UX design
    More than 120 user flows were designed

  • Usability Test*
    13 distinct modules were tested with usability testing sessions with TEB customers

  • UI Design*
    The visual concept was generated and +800 screens along with design system were designed

To serve its private customers through a mobile application (CEPTETEB), TEB has been working with I-AM Istanbul. When I joined the team, the application was already designed and live. As the financial needs evolve and transform with time, during my involvement I designed several screens and flows and redesigned some others according to the existing design system, light and dark themes while continuing to extend it.


Our focus was to continue providing a seamless, simple and engaging experience for TEB's online banking platform for private customers.

My Involvment

Some of the projects I've been involved in for the private platform:

  • Becoming a customer flow (without going to the banks)

  • Log in screens

  • Verification checks

  • Investment flows

  • Several dialogues

  • Illustrations

  • Design system

Exploration & System Analysis

To comprehend business requirements, customers' financial needs and behaviours we conducted

Design &

Putting the latest technologies into work, we implemented automated onboarding processes, enabling users to submit necessary documents online with automated verifications among others.


In order to test and deliver the needs, the following methods were used:

  • Lo-fi Prototyping*
    Paper prototyping and sketches were utilised

  • Usability Test*
    Some flows were tested with usability testing sessions depending on their complexity.

  • UI Design*
    The interfaces were designed according to the user needs. Additions were provided to the Design System.
