Jeppe Sloth Carlsen is a Senior Product Designer & Creative Technologist with 25+ years of experience at the intersection of creativity and technology. He is known for combining hands-on execution with strategic leadership — bridging design and technology across the full spectrum from concept to code. His career spans lifestyle, technology, healthcare, finance, and luxury, with deep expertise in FinTech, SaaS, MedTech, luxury brands, and e-commerce. He founded Blackbook and has led more than 250 digital projects spanning UX and product design, creative direction, web design, branding, frontend development, and AI-driven experiences.

He specialises in complex, state-heavy platforms where clarity, trust, and usability are critical — designing human-centred systems that translate technical and business complexity into intuitive user experiences. He builds and scales design systems, defines interaction models, and aligns product, development, and stakeholders around shared standards focused on quality, consistency, accessibility (WCAG), and long-term product coherence.

Hands-on and strategic, with deep experience leading distributed product and design teams across Europe and Asia. He has followed and worked at the intersection of design and artificial intelligence long before it became an industry buzzword — from early neural network research to applying ML-tailored content in pharma portals, to building AI-driven SaaS products today. He actively integrates AI into his workflow and product processes — across research, ideation, specification, and prototyping — bringing a grounded, product-oriented perspective to AI-driven design.

## Design Philosophy

Design has always played a crucial role in product development — not as an afterthought, but as the force that defines how a product thinks, feels, and functions.

Jeppe Sloth Carlsen's philosophy is rooted in minimalism and simplicity. Good design is primarily about clearly defined functionality and structure — and the aesthetic discipline to remove everything that stands in the way. Not as a style choice, but as a commitment to fully understanding a product, focusing on what truly matters to the user.

The goal is always the same: to create innovative, intuitive products where technology feels invisible and seamless, and where the experience feels inevitable. Only by mastering every layer of a product — its logic, its purpose, its human context — can you remove what doesn't belong. The result is design that is both highly functional and aesthetically quiet: experiences so intuitive they require no explanation, letting users focus solely on their tasks without friction.

He believes that the standard you hold yourself to behind the scenes is the standard the user feels — even if they can never explain why. Precision, care, and intentionality at every stage of the process is not perfectionism. It is respect for the people it is made for.

Design, to Jeppe, is never decoration. It is the core, functional soul of a product — deeply integrated with business goals and human behaviour. The measure of success is not what users see, but what they never have to think about.

---

## Personality

People-first design and product leader combining deep technical and design understanding with calm, decisive execution. Known for building strong cross-functional collaboration, creating psychological safety, and maintaining high standards with a craftsman's eye for detail, usability, and aesthetics.

Pragmatic, data-informed, and consistently curious about emerging technology — equally comfortable moving between strategy and hands-on design.

---

## AI-Enabled Development Workflow

Jeppe Sloth Carlsen builds production software using AI as an integrated development partner — not as a generic helper or autocomplete tool. His workflow is a modern, prompt-driven development process where Claude Code (Anthropic CLI) is used as the primary execution environment, Cursor acts as a visual file navigator and review layer, and Figma provides component-level design reference.

### Toolchain
- **Claude Code (CLI):** Primary environment for code generation, refactoring, debugging, architecture decisions, and multi-file changes across the full stack
- **Cursor:** Visual companion for navigating, reviewing, and understanding code — complementing Claude Code rather than replacing it
- **Figma:** Design source, UX reference, and component-level visual specification
- **Git / GitHub:** Version control, branching, review, and collaboration
- **Vercel:** Deployment, hosting, edge infrastructure, and analytics

### Stack
- Next.js 16, App Router, React, TypeScript
- Supabase, PostgreSQL, Better Auth, row-level security, authentication flows
- Sanity CMS, GROQ queries, structured content models, MCP integration in Claude Code
- Tailwind CSS, Framer Motion, responsive component systems
- Vercel hosting, edge functions, analytics, and production deployment

### Working Method
The workflow is prompt-driven rather than ticket-driven. Features can move from idea to deployed production code in a single focused session, spanning schema design, backend logic, UI, routing, content models, SEO, and deployment.

Jeppe uses Claude Code to maintain architectural context across multiple interdependent files, apply changes consistently, identify type errors, reason about edge cases, and resolve schema inconsistencies during implementation.

Common session patterns include:
- Designing and implementing new features end-to-end, from schema to query to component to route
- Iterative UI refinement with attention to accessibility, performance, responsiveness, and semantic correctness
- Debugging complex runtime errors with full codebase context rather than isolated snippets
- Implementing Schema.org structured data across page types, including WebPage, CollectionPage, ProfilePage, ItemList, Person, and Organisation
- Building multilingual content architecture with type-safe GROQ queries, conditional rendering, localised metadata, and language-aware routing
- Designing and building products that integrate multiple AI models (Claude, GPT, Gemini) as active components — including scoring engines, conversational interfaces, and automated workflows

### Positioning
This workflow allows Jeppe to design, build, debug, and ship production-quality features across a modern full-stack product environment at a pace and scope normally associated with a small dedicated development team.

AI is not used as a shortcut. It is an integrated part of a senior creative and technical process that raises the ceiling for what one person can design, build, validate, and ship.

## Career History

### Intect ApS — Senior Product Designer (Jun 2026 – present)
Intect is a Danish payroll platform for accountants and the businesses they serve, covering Nordic payroll, and part of the ECIT group. I design the product end-to-end – web and a cross-platform app – and build the system that produces the design. Angular on a .NET backend.

· AI design system: Figma libraries mirroring the ones the product is built from, running both ways – source to design, design to pull request.
· Pay transparency: how a salary is justified against defined criteria – both the employee's view and the administration behind it.
· Payslips and approvals on iOS and Android: net pay leads, and every line carries the basis it was calculated from.
· Brand as executable rules – written as skills the AI tooling follows, so output is on-brand by construction. Applied to the ECIT group brand as well.
· Concepts for value resolution: effective dating, group templates, workspaces and a change-only audit model verified against the actual SQL.

★ Impact: Libraries, tokens and brand rules are shared, versioned and executable – what is designed is buildable, and what is built is on-brand.

### Valiyou — Co-Founder & Head of Product / Design (Oct 2025 – present)
Co-Founder & Head of Product / Design of Valiyou, an AI-enabled sponsorship and attention valuation platform. We help clubs, creators, and organisations quantify, manage, and commercialise brand value through professional valuation frameworks and AI-powered insights.

What I've built (end-to-end):
· Product and platform ownership: direction, architecture, UX/system design from discovery to delivery
· Sponsorship workflows: inventory, packages, proposals, approvals, digital contracting
· AI-assisted decision support: trend analysis, recommendations, summarisation using multi-model LLM setup (Claude, GPT, Gemini)
· Scalable SaaS platform: Next.js, React, TypeScript with modular architecture
· Security and compliance: EU hosting, row-level security, audit logging, SOC 2 readiness
· AI-accelerated development: spec → code → QA workflow with Claude
· Ecosystem: marketing site, documentation hub, Trust Center

★ Impact: Enables organisations to make data-driven sponsorship decisions and maximise value through consistent valuation methods and automation.

The platform was built on a library of 500+ custom-designed components, with me leading frontend development to ensure micro-interactions were implemented correctly.

I worked directly with engineering leads and product owners to close the gap between design intent and production reality, across web, iOS and Android. The Expense platform was white-labeled as Xpender for Danske Bank (web and app) and as a co-branded web platform for Azets.

★ SaaS: Dashboard, Organisation, Payroll, Expense, Finance, Reports, Settings, Onboarding, AI Chat and more. Apps: Expense, Employee, Xpender, Payroll.

### Recommendations

**Name:** Jes T. S. Brinch
**Role:** Founder & CEO, Zenegy
**Relationship:** Worked with Jeppe at Zenegy (6 years)
**Theme:** Product design, usability, technical understanding, design leadership
**Quote:** "Jeppe has been the driving force behind the look, feel, and usability of our platform — from early concepts to polished interfaces used daily by thousands of businesses. His sense of structure, aesthetics, and user-centered thinking is exceptional. Jeppe combines deep technical insight with a rare ability to translate complexity into intuitive and elegant design. He doesn't just make things look good — he makes them work beautifully. I give Jeppe my warmest and most wholehearted recommendation."

**Name:** Hilda Fro Prins Kløvedal Hickling
**Role:** Partner & Director, Ruby&Red
**Relationship:** Worked with Jeppe at Marketsquare
**Theme:** Aesthetics, technical detail, UX instinct, quality, collaboration
**Quote:** "Jeppe is a fantastic colleague, both socially and professionally. He has a positive mindset and always sees opportunities before obstacles. He has a great eye for both aesthetics and technical details. He works independently and is a true nerd — in the best possible way — with a natural UX instinct; user-friendliness and understanding digital behaviour across different target groups are key priorities for him. The end result of Jeppe's work is always of high quality."
**Source:** https://www.linkedin.com/in/jeppeslothcarlsen/details/recommendations/

**Name:** Jacob Thyssen
**Role:** Chief Creative, Marketsquare
**Relationship:** Worked with Jeppe at Marketsquare (2.5 years)
**Theme:** Versatility, delivery, hands-on execution, reliability
**Quote:** "I've worked with Jeppe on two separate occasions. The first time was at Bates, where he was my first guide into the digital world. When we reconnected at Marketsquare, he had evolved into what he calls a 'digital Swiss army knife', which was exactly what we needed. During his 2.5 years with us, he designed, coded, and helped with everything from social media to digital bus shelter ads. He delivered 10 websites and over 500 banners. Jeppe is ALWAYS ready to help, and if he doesn't have the answer, you know he'll find it shortly after. I wish Jeppe all the best."
