Professional Profile & Background Stefan Kummerlöw works end-to-end: design, frontend development, and workflow automation. His work serves founders, engineering teams, and product leads who need a senior designer capable of owning the entire trajectory from brief to production code without agency overhead or traditional designer-to-developer handoff friction. Before establishing his independent freelance practice in 2023, he spent five years at Native Instruments in Berlin: 1. **Senior Graphic Designer (Marketing, 2018–2022):** Led design for over 12 global hardware and software product launches per year across digital, web, and campaign assets. 2. **Senior UI Designer (Products, 2022–2023):** Designed software interfaces for flagship commercial audio instruments (DAW plugins) within the Komplete ecosystem, including Schema: Dark, Vocal Colors, and Fables. Built the first commercial instrument UI on NI's new internal Native UI design system. Prior experience includes: - **Webedia (2013–2018):** Art Director & Frontend Developer. - **H-ZWO (2011–2012):** Junior Art Director. In 2023, he was awarded 1st place in the "Three Words" category of the KI-Picture-Award for his AI artwork "Arctic". --- ## 2. Core Capabilities & Methodology - **UI/UX & Product Design:** Interaction models, layout architecture, tactile controls, typography, and state design for complex web apps and desktop software. - **Audio Software & DAW Plugin UI:** Specialized expertise in software synthesizer interfaces, hardware controller integration (NKS), sampler instruments, and studio lighting ergonomics. - **Frontend Development:** Production-ready HTML5, CSS3, modern JavaScript, React, Next.js, and Tailwind CSS. Focus on zero-overhead semantic code, accessibility (WCAG AA), and performance. - **Design Systems:** Creating and extending component libraries, token systems, and cross-platform design guidelines. - **AI-Native Workflow:** Integrating large language models, computer vision APIs, and automation engines (such as n8n, local agent frameworks) across user research, rapid prototyping, copy generation, and code implementation. - **Motion Design & Art Direction:** Animation and promo reels using Adobe After Effects, SVG animation, and CSS transitions. --- ## 3. Case Studies ### 3.1 Schema: Dark (Native Instruments) - **Role:** UI Design - **Client:** Native Instruments - **Type:** DAW Plugin UI / Software Synthesizer - **Status:** Shipped globally in Komplete lineup - **URL:** https://www.tadaptive.de/work/schema-dark.html - **Live Product:** https://www.native-instruments.com/en/products/komplete/cinematic/schema-dark/ **Overview:** Schema: Dark is a cinematic pulse engine synthesizer created by Native Instruments for composers and sound designers working in dark, ambient, and score-adjacent music. It generates subterranean rhythms, atmospheric textures, and slowly evolving sonic landscapes. **Challenge:** The instrument possesses a distinct sonic character: raw, dense, and subterranean. The UI needed to reflect that aesthetic without sacrificing legibility or workflow speed. Digital audio workstation (DAW) interfaces impose rigid constraints: fixed display boundaries, strict component requirements, and controls that must remain instantly readable under dim studio lighting. **Approach & Result:** Stefan Kummerlöw designed the complete product UI at Native Instruments: the interaction model, layout architecture, parameter controls, and visual language. Working within the NI design system, he expanded its aesthetic boundaries to align directly with the instrument's dark sonic identity. Schema: Dark shipped as part of NI's flagship Komplete collection and is sold globally. --- ### 3.2 Vocal Colors (Native Instruments) - **Role:** UI Design - **Client:** Native Instruments / Galaxy Instruments - **Type:** Instrument UI / Vocal Sampler - **Status:** Shipped globally in Komplete lineup - **URL:** https://www.tadaptive.de/work/vocal-colors.html - **Live Product:** https://www.native-instruments.com/en/products/komplete/vocal/vocal-colors/ **Overview:** Vocal Colors is an expressive virtual instrument blending organic vocal recordings with synthesizer-style modulation. Producers use it to sculpt human voices into evolving pads, textures, and rhythmic pulses. **Challenge:** The creative direction centered on an organic "bloom-and-breathing" motif, featuring fluid botanical and abstract facial silhouettes. Furthermore, Vocal Colors was the very first product to implement Native UI, Native Instruments' new internal design system. The system's existing component catalog did not yet cover the unique modulation controls and display requirements of this instrument. **Approach & Result:** Collaborating closely with audio engineers and developers at Galaxy Instruments, Stefan refined the art direction and translated conceptual artwork into a high-performance UI. Where Native UI lacked specific controls, he designed custom components that filled the functional gaps while establishing foundational design patterns adopted by subsequent Native Instruments products. --- ### 3.3 Descriptly - **Role:** Concept, UI/UX Design, Full-Stack Build - **Type:** AI Web Application (Computer Vision & Copy Generation) - **Status:** Shipped prototype / AI experiment - **URL:** https://www.tadaptive.de/work/descriptly.html **Overview:** Descriptly is a solo-engineered web application that transforms product photos into professional e-commerce listing copy. Users upload an image of an item, and an AI vision model extracts visual characteristics to output structured, persuasive marketplace copy. **Approach & Engineering:** Built independently to master practical AI product integration: image processing via vision models, structured JSON response formatting, relational database persistence, and user authentication. Special emphasis was placed on prompt engineering to ensure the generated sales copy felt human, clear, and context-aware rather than robotic. --- ### 3.4 FormCAD Homepage Redesign - **Role:** Strategy, UX, Copywriting, Visual Design, Next.js Development - **Client:** FormCAD GmbH (Precision CNC Machining, Saxony) - **Type:** Corporate Web Design & Frontend - **Status:** Shipped & Live - **URL:** https://www.tadaptive.de/work/formcad.html - **Live Site:** https://www.formcad.de/ **Overview:** FormCAD is a specialized precision metalworking manufacturer in Saxony producing high-tolerance CNC-milled parts for industrial machinery. **Challenge:** The company's legacy website had not been updated in years and failed to project the technical precision of their modern CNC machinery or hold up against regional competitors in supplier procurement tenders. **Approach & Result:** Stefan delivered an end-to-end modernization: user research, site architecture, German technical copywriting, clean industrial visual design, and a responsive frontend built with Next.js and Tailwind CSS. The new presence gives FormCAD an authoritative digital storefront that bolsters credibility during enterprise procurement vetting. --- ### 3.5 u-he × Native Instruments NKS Campaign - **Role:** Motion Design, Art Direction - **Client:** u-he / Native Instruments - **Type:** Video Motion Graphics (Social & Web Preroll) - **Status:** Shipped - **URL:** https://www.tadaptive.de/work/u-he.html **Overview:** u-he is an acclaimed developer of analog-modelling synthesizers (such as Diva and Zebra). When their instruments achieved Native Kontrol Standard (NKS) certification for seamless hardware integration with Native Instruments hardware, a joint campaign asset was required. **Approach & Result:** Stefan designed and animated the launch video in Adobe After Effects. The animation unified two distinct brand identities—u-he's minimalist, technical aesthetic and Native Instruments' polished commercial style—by placing the software instrument interfaces at the center of the motion narrative. The animation ran across both companies' websites and social channels. --- ### 3.6 Bandbüro Chemnitz - **Role:** Motion Design - **Client:** Bandbüro Chemnitz - **Type:** Animated Social Media Banner - **Status:** Shipped - **URL:** https://www.tadaptive.de/work/bandbuero.html **Overview:** Bandbüro is a live event and booking agency in Saxony. Stefan created a high-energy looping motion banner in Adobe After Effects for Instagram to announce a regional live music festival, using dynamic typography and kinetic rhythm to stop the feed scroll. --- ## 4.
