Jan Vainio – Senior UX / Product Designer | Complex Systems, Data & Accessibility
Welcome – nice of you to drop by!
I’m Jan — a Helsinki -based Senior UX- / Product Designer
I design digital products where complexity needs to become clarity. Over the past 10+ years, I’ve worked across healthcare, SaaS, FMCG, and consumer services — helping teams turn data, workflows, and ideas into intuitive, reliable, and meaningful user experiences.
At heart, I’m a hands-on problem solver — equally comfortable shaping strategy, refining interaction details, or building things from the ground up.

About
I’m passionate about designing experiences that are not only visually refined, but genuinely useful
— especially in complex, real-world contexts
My work sits at the intersection of user needs, business goals, and technical reality. I enjoy shaping ideas early, navigating ambiguity, and bringing structure to complexity through research, interaction design, and iteration.
In recent years, I’ve focused on data-intensive and regulated environments within clinical research, where clarity, accessibility, and reliability are critical. Designing for these contexts has strengthened my ability to reduce cognitive load, support decision-making, and build user trust.
What also shapes me as a designer is my hands-on background beyond digital work. I’ve built boats, renovated apartments, constructed terraces and cottages, and worked across a wide range of practical environments. These experiences have grounded my approach — I naturally think in systems, constraints, materials, and real-world use.
I’m curious by nature and constantly learning — whether it’s new tools, technologies, or entirely new domains. I enjoy stepping into unfamiliar challenges and turning them into structured, solvable problems.

I believe the best solutions come from combining structured thinking with hands-on exploration — not just defining ideas, but actively shaping and refining them.
Areas of Competence
This is where strategy meets execution: The skills, methods and tools I use to turn complexity into clear, usable and visually refined experiences.
Core
Designing intuitive user flows for complex systems and diverse user groups. My work focuses on reducing friction, improving efficiency, and supporting real-world use.
Specialization
Strong foundation in typography, layout, hierarchy, and visual storytelling. I create interfaces that are both aesthetically refined and functionally clear.
Research & Process
I use prototyping as a thinking tool — to explore ideas, align stakeholders and validate solutions early.
Roles where I’ve combined UX, product thinking, systems design and hands-on execution — from regulated healthcare and SaaS to campaigns, gaming and media.
16+ years in digital product workHealthcare, SaaS, FMCG, gamingResearch design implementationDesign systems & accessibility
Recent & key roles
Most relevant for product, UX and complex digital service work.
Led UX design for global clinical research platforms, including the SmartSignals™ eCOA product family used in highly regulated, data-intensive environments.
Worked across the full design process — from research and workflow definition to prototyping, usability validation, UI design and implementation support — helping transform complex trial operations into clearer, more reliable user experiences.
Highlights
Designed data-heavy dashboards, study setup tools and multi-device workflows for operational teams, clinicians and patients
Reduced cognitive load in complex workflows where clarity, trust and accuracy were business-critical
Contributed to scalable design systems and shared UI components across product areas
Worked in a highly regulated context with strong emphasis on WCAG accessibility and usability
Supported solutions connected to faster, more efficient clinical research delivery
Led frontend work and UI improvements for digital gaming platforms and internal operational tools.
The role combined team coordination, interface refinement and close collaboration with development, with a strong focus on smooth user flows, operational efficiency and commercially effective experiences.
Highlights
Improved customer-facing interfaces across online gaming services
Designed internal tools supporting slot machine maintenance and daily operations
Strengthened collaboration between design thinking and engineering execution
Worked in a fast-moving environment where usability and performance had direct business impact
Designed and developed 200+ digital campaigns and service concepts for major consumer brands in a small, fast-moving startup environment.
Worked end-to-end from concept and visual design to frontend implementation, helping brands create engaging, usable and conversion-oriented campaign experiences.
Highlights
Delivered award-winning digital campaigns for brands such as Nestlé, Lindt, Coca-Cola, Fazer and Vaasan
Combined strong visual design with practical UX and frontend execution
Created campaign mechanics, loyalty concepts and promotional experiences across web channels
Contributed to webshop-related projects, including maintenance and UX/UI improvements
Earlier experience
Foundational roles that shaped my sense of systems, communication, production and craft.
Coordinated live news production in a high-pressure environment where clarity, timing and structured information flow were essential.
The role sharpened my sense of hierarchy, pacing, communication and fast decision-making — skills that still influence how I design complex user experiences today.
Highlights
Coordinated live broadcasts with journalists, editors and technical teams
Ensured timing, sequence and on-air clarity under pressure
Developed a strong eye for visual hierarchy and critical communication
Worked on one of Europe’s early interactive TV platforms, helping bring multiple digital services into one unified user experience.
The work involved service orchestration, operational coordination and system-level thinking long before product design became a common term in the industry.
Highlights
Helped integrate news, consumer services and interactive functionality into a shared platform
Worked across technical, operational and user-facing concerns
Contributed to services that scaled to several hundred thousand users
Worked across web design, frontend development, branding, illustration and editorial layout for a wide variety of clients and projects.
This broad hands-on background built the foundation for my later product design work and strengthened both my craft and my practical understanding of implementation.
Highlights
Designed websites, visual identities, illustrations and printed materials
Created 40+ book layouts and numerous brochures and publications
Built long-term practical understanding of design, code and production realities
