I craft digital experiences and build products that work — beautifully and strategically.
I'm Semih Çelik, a Product Designer based in Istanbul with 5+ years of experience crafting digital products in Fintech and Edtech. Currently at Zip Türkiye, where I lead the design of Buy Now Pay Later experiences used by hundreds of thousands of users.
My background spans the full design spectrum — from user research and information architecture to design systems and interaction design. I believe the best interfaces are the ones that disappear, letting users accomplish their goals without friction.
Pixel-perfect interfaces with meticulous attention to typography, spacing, and visual hierarchy.
Uncovering user needs through qualitative interviews, usability tests, and data analysis.
Building scalable component libraries that keep teams aligned and products consistent.
Bridging business goals with user needs to define product direction and roadmaps.
Crafting meaningful micro-interactions and transitions that delight without distracting.
Specialized in financial product design — simplifying complex flows like payments, BNPL, and wallets.
Clear, developer-friendly specifications with a deep understanding of front-end constraints.
Inclusive design practices ensuring products are usable by everyone, every time.
Deep-dive into user needs, business goals, and constraints. Interviews, competitive analysis, and data review to form a clear problem statement.
Synthesize research into user personas, journey maps, and prioritized problem areas. Align stakeholders on what we're solving and what success looks like.
From low-fidelity wireframes to polished high-fidelity prototypes. Rapid iteration, design critique, and constant validation against user needs.
Detailed handoff specs, component documentation, and close collaboration with engineers to ensure the design ships exactly as intended.
Leading end-to-end product design for Turkey's BNPL platform. Responsible for the complete redesign of the consumer app, the merchant checkout flow, and the internal operations dashboard. Built and maintained the company's first cross-platform design system.
Designed core mobile flows for Turkey's digital wallet and international remittance product. Conducted user research and usability testing to optimize the onboarding, KYC, and money transfer journeys.
Redesigned the AI analytics platform dashboard, creating data visualization components and a scalable component library. Worked closely with data scientists to translate complex ML outputs into intuitive interfaces for non-technical users.
Designed the web checkout experience and merchant dashboard for a payment facilitation platform. Focused on reducing friction in the payment flow, achieving a measurable improvement in checkout completion rate.
I'm open to new opportunities — whether it's a full-time role, a freelance project, or just a good conversation about design.
