Selected work

Five projects that show how I move from research and systems thinking to shipped interfaces, hardware and working AI.

PASSO · AktifBank — 2022–2026

The hands-on designer of a bank-backed SuperApp

The active hands-on UX designer across PASSO — a publicly live, multi-vertical SuperApp spanning ticketing, regulated service banking (multi-currency investment, loans, FAST instant payments), e-commerce, transport, lottery and NFT ticketing. I owned research, information architecture, interaction and UI end to end, and built the design system that kept design and engineering in sync across the ecosystem.

SuperApp screens — discovery, ticket selection, interactive seat map.

TakeCare · B.Sc. graduation — 2012

A brain–computer interface for bedridden patients

An EEG brain–computer-interface assistive system that lets bedridden patients manage their own care — controlling the bed, lights, A/C and media, communicating via a spelling-to-speech keyboard, and calling for help. I designed the entire pictogram-based interface (patient and doctor side) and built a working prototype with three engineers.

TakeCare main menu — a brain-signal-driven radial interface: My Comfort, Help, Stop, Fun
TakeCare environmental control — lights, air conditioner, bed positioner
TakeCare augmentative communication — on-screen scanning keyboard with speech synthesis
Project Sheeperd · METU — 2014

An outdoor interaction game played with a drone

An experimental outdoor multiplayer game where players track a quadcopter's projected light beam through wearable Arduino caps with light sensors and haptic feedback — a physical-computing / phygital interaction prototype built by a six-person team.

Coolin / YAKO Teknoloji · Co-founder — 2016–2019

A grant-funded medical-IoT startup

Co-founder and designer of a smart portable insulin cooler — a phygital hardware + software product for people with diabetes. I designed the mobile app, branding, hardware packaging, CAD and investor materials. Backed by a TÜBİTAK research grant, with two filed patent applications.

AI Portfolio System · 2026

An AI that can answer for me — grounded in evidence

This site is backed by a multi-agent system I built: it ingests my career archive, holds it to an evidence-and-clearance contract, and powers a recruiter chat agent that answers only from verified facts — and says so when it doesn't know. Built with Claude / Gemini, Node and disciplined prompt engineering. Live proof of AI inside the design process.

Don't take my word for it — ask my AI.

A recruiter chat agent grounded entirely in my verified profile. It answers from evidence, admits what it doesn't know, and never invents a metric. It's also a working sample of how I build with AI.
