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.
Who Uses It
Track workouts, review stroke profiles, compare sessions and compete in virtual regattas
Monitor multiple boats live, assign athletes to teams, analyze crew performance
Shared logbooks, leaderboards and season-long performance data
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 & Solutions
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.
Screens had to handle real device states: not paired, pairing, streaming, connection lost.
→Designed explicit states for every connectivity scenario.
Short cycles from client need to developer handoff.
→Prioritized directly with the PM and delivered specs sprint by sprint.
