Design-driven solutions, technically sound.
I'm Moritz Fieler. I work end-to-end: user research, design strategy, prototyping, and production code. That's where the best products come from.
The Rare Combination
Design strategy, user research, and full-stack development in one person — from concept to production.
Design Strategy & User Research
Professional UX design and user research from Stuttgart. User-centered concept development for web development and digital products with Figma, prototyping and usability testing.
Frontend Development
Modern web development from Stuttgart with Vue.js, Nuxt.js and TypeScript. Responsive frontend development for performant and maintainable web applications.
Backend & APIs
Full-stack web development with Node.js, REST APIs and databases. Seamless integration of frontend and backend for complete web applications.
Flagship Projects.
Three projects that define my approach: design strategy meets technical excellence
Paquita Pilates — Corporate Identity & Website Relaunch
A complete branding system for a boutique Pilates studio in Stuttgart. From logo and color palette through responsive website — every element designed to authentically represent the studio's philosophy and aesthetic.
Pilateq — Booking System for Boutique Pilates Studios
A booking and studio management platform built specifically for small, therapeutic Pilates studios. Pilateq handles scheduling, credits, payments, and client communication — intuitive for studio owners, elegant for clients.

HIQER — Persuasion for the Outdoors
What if your phone made you put your phone away? HIQER turns outdoor exploration into a competitive quest — GPS triggers, XP, leaderboards, and a companion Watch app designed so the screen stays in your pocket.
Kischde — Trade Within Trust
No marketplace noise. No strangers. Just a circle of people you trust — and the things you no longer need. Kischde is a swipe-first trading app built on the belief that giving should feel better than selling.
B.E.A.S.T. — Charging with Character for Mercedes-AMG
How do you bring heartbeat back to electric vehicles? In a Winter 2022/23 interdisciplinary project, our HdM Stuttgart team collaborated with Mercedes-AMG to prototype multimodal charging experiences — light, haptics, and sound — validated through real user testing in the Mobile Lab.
Connected E-Mobility — One Ecosystem, One Interface
What if your car, wallbox, solar panels, and home grid finally spoke the same language? My bachelor thesis developed a connected e-mobility interface giving Mercedes customers the unified control their ecosystem deserves.
