Overview

A connected performance platform for rowing teams.

NK LiNK Logbook is the digital training companion for rowers, coxswains and coaches, built by Nielsen-Kellerman — a US manufacturer of rowing performance electronics. The app pairs with NK's on-water devices (SpeedCoach GPS, CoxBox GPS, EmPower Oarlock) via Bluetooth to import session data, analyze performance stroke by stroke, and stream live metrics to coaches and spectators.

The platform spans a web logbook for deep session analysis and team management, and a mobile app for device pairing, data import and live streaming.

Users

Who Uses It

Athletes

Track workouts, review stroke profiles, compare sessions and compete in virtual regattas

Coaches

Monitor multiple boats live, assign athletes to teams, analyze crew performance

Teams & Clubs

Shared logbooks, leaderboards and season-long performance data

Role

My Role

I joined an established product with a large existing design system and worked in a continuous delivery rhythm — designing new features on a daily basis, driven directly by user and client needs.

  • Designed new features end-to-end within the existing design system — from request to developer-ready specs
  • Improved existing flows across both web and mobile experiences
  • Designed data-heavy interfaces: workout logs, session analysis, leaderboards and live tracking views
  • Worked with IoT constraints — flows dependent on Bluetooth pairing, device states and live data streaming
  • Collaborated in a Scrum team with PM, business analysts, developers and QA on a sprint cadence
Challenges

Challenges & Solutions

Designing inside a mature system

Every new feature had to feel native to an interface users already knew.

Studied existing patterns first and extended them instead of inventing parallel ones.

IoT-dependent flows

Screens had to handle real device states: not paired, pairing, streaming, connection lost.

Designed explicit states for every connectivity scenario.

Daily feature cadence

Short cycles from client need to developer handoff.

Prioritized directly with the PM and delivered specs sprint by sprint.

What this project strengthened: designing within an established design system at speed — and making IoT complexity (devices, pairing, live data) feel invisible to the athlete on the water.
