Senior🎓
Top SchoolKonstantinos Mastorakis is a Site Reliability Engineer based in Utrecht with eight years of experience at the intersection of geospatial engineering and scalable software. He has built and led map data analytics platforms at TomTom, drove automation and cloud-based big-data geoprocessing at Asset.Insight, and now applies those skills to ensure reliability at Booking.com. His work blends geospatial domain expertise—photogrammetry, 3D city models, point-cloud processing—with practical SRE practices, enabling data-driven QA/QC and company-wide platform adoption. Konstantinos prototyped novel map change detection algorithms and implemented git-style versioning for 3D city models, showing a penchant for turning research prototypes into production tools. He also creates educational Python content and has experience unifying fragmented codebases into reusable libraries for teams. This combination of hands-on geodata mastery and production reliability makes him effective at scaling complex geo-applications.
