Available for frontend & mobile opportunities

From idea to launch — I build products that solve real problems.

I'm Kristian Jensen, a frontend and mobile developer in Bergen. I take products from early ideas to polished web and app experiences with React, React Native and TypeScript.

Mammavenn

A safer, warmer way for parents to find community during parental leave.

I design and develop Mammavenn across web and mobile. The product brings local discovery, meetups, posts, profiles and safer communication together in one calm experience.

The challenge

Connection matters. Starting it should feel easy.

New parents can feel isolated, while broad social platforms often feel noisy or impersonal. Mammavenn is designed to feel welcoming, local and safe.

My role

Product thinking, design and development.

I shaped the concept, user flows, visual system and implementation, including authentication, profiles, media, maps, events, social interactions and moderation.

01Local discovery

Find parents, meetups and helpful places nearby.

02Community feed

Share moments, ask questions and join conversations.

03Meetups & chat

Move naturally from a connection to a real meeting.

04Safety tools

Privacy, reporting and moderation support safer use.

Current outcome

A working product moving toward launch.

Mammavenn is live on the web, with iOS and Android release builds prepared for store review. The project demonstrates end-to-end product ownership across design, frontend, mobile and backend integration.

About

Practical, curious and product-minded.

I care about the whole experience, not only the screen in front of me.

My strongest work sits between frontend development and product design. I enjoy making complex flows understandable, building reusable components and polishing the small details that make a product feel reliable.

I am especially motivated by products with real everyday value: communities, tools and services that help people feel informed, supported or simply less frustrated.
