Green Idea OÜ
Green Idea OÜ is a small, independent studio based in Estonia, working across two disciplines: mobile app development and data & AI consulting. Different crafts, same preference for depth over breadth.
Mark Litwintschik works with clients across the UK, US, Sweden, Ireland, and Germany on big data, AI, GIS, and networking projects — benchmarking database engines, building satellite-imagery pipelines, and working through large-scale geospatial datasets.

A sleep hygiene and wind-down app: breathing exercises, sleep sounds, and an evening journal to help build a calmer nightly routine.
