Kerim Tapkan is an Istanbul-based naval architect, senior project manager and science-fiction author with more than twenty-five years in custom yacht construction and refit. His engineering background shapes the spacecraft, technologies and civilizations of P.X, while the fiction follows the people and families caught within a much larger universe. P.X: No Man’s Space opens a planned trilogy built around first contact, hidden history and an interstellar conflict approaching Earth. The setting continues through P.X Untold companion stories, including The Abstention, and The Snorvix Codex, an in-universe archive of histories, species, ships and technologies. Developed as essentially a one-person project alongside his professional career, P.X also has an explorable website with character profiles, worldbuilding, artwork, short films and arcade experiences. His article “Engineering the Imagined” appeared in SNAME’s Marine Technology magazine in October 2026.
