SitePlan GmbH

Bringing structure to a fast-moving civil engineering software company — full Android rewrite, new design system, and introducing Shape Up to a team with no prior process.

Context

SitePlan builds mobile and web tools for excavation and underground construction — think GPS-based site staking, digital surveying, and location-anchored photo documentation for construction teams in the field. Their own tagline is “the Google Maps for excavation”. Based in Austria, their clients span the DACH region and beyond. When I joined, the team was still early in formalizing its engineering and product workflows.

What I did

I came in as an Android engineer but took on a much wider scope. On the process side, I helped set up a shared knowledge base to bring documentation and collaboration into one place. I’m currently introducing Shape Up as the team’s development methodology, establishing a cycle-based rhythm in place of the ad-hoc approach. I also contributed to introducing OKRs to align the team around measurable outcomes.

On the design side, I created a new design language for the Android app — a coherent design system that the iOS team is now adopting as well. I also redesigned the web app, focusing on streamlining user flows wherever I encountered friction.

On the engineering side, I rewrote the Android app from scratch: new architecture, new UI, new foundations. I also introduced Kotlin Multiplatform to share core business logic between Android and iOS — reducing duplication and keeping platform implementations in sync.

Outcome

  • Complete Android app rewrite — new architecture, new design, shipped to production
  • New design system adopted across Android and picked up by iOS
  • Web app redesigned with improved flows and visual consistency
  • Shared knowledge base established as the central collaboration hub
  • Shape Up currently being introduced as the team’s product development process
  • KMP libraries shared across platforms for the first time
  • OKRs introduced as a planning and alignment framework
