Eetu Rantanen Full-stack product engineer Tampere, Finland

Building useful products with care, from UX details to shipped software.

Identity

Frontend-strong product engineer with a design eye and growing full-stack range. I’m strongest where UX quality, product thinking, and implementation meet. Husband, dad of two boys and a dog — former semi-pro volleyball athlete, builder by heart.

Currently

Building Liquipedia at Team Liquid, where I work on shared product systems, user-facing features, and platform improvements in a product team. On the side, I build and test my own product ideas.

What I bring

Strong frontend craft with product instincts.

Comfort turning fuzzy ideas into clear, shipped experiences.

Experience working with design, product, and engineering in real teams.

Able to move between UX detail, system thinking, and implementation.

Interests

UX that actually makes sense, fast iteration, tools that don't suck, and products that earn their place. AFK: drums, darts, and various sports where a ball is present.

Product work I've shaped across teams, systems, and zero-to-one ideas

Liquipedia

Liquipedia is a Team Liquid product and one of the biggest esports wiki platforms in the world. I worked on user-facing modules, templates, and platform features, with a focus on standardizing shared systems, shipping redesigns, and improving common functionality site-wide.

SignCircle

SignCircle was a sports-tech startup that I co-founded and led from idea to alpha. I built the product across strategy, brand, design, marketing site, and application development, helping grow it to around 200 alpha signups and a 300-person waitlist. It became a defining lesson in founder-led product execution and business fit.

Team Liquid

Team Liquid is a leading global esports organization, consistently ranking top in competitive achievements, viewership metrics, and fan engagement. The organization employs 250+ professionals globally as well as other strategic partnerships across various industries.

Vennu

On this freelance project, I designed and built a custom Webflow website for Vennu, a healthcare company based in Turku, Finland. The project was part of a complete company rebrand, requiring a website that balanced visual appeal with functional healthcare-specific features.

Kuasi

As Lead Webflow Developer, I spearheaded the technical implementation of client projects while collaborating with designers, project managers, and clients to deliver high-quality solutions on time and within scope.

Personal Site

In order of expanding my technical knowledge, I wanted to development a new personal website that served as both a portfolio showcase and a learning playground. This project allowed me to deepen my knowledge across multiple technologies and concepts while implementing professional-grade solution to my own use.

Open to the right next thing whether that’s a product team, a startup, or a good conversation.
