• Career trajectory runs Ruse olympiad prodigy -> Leanplum intern (2019) -> Leanplum Java backend (2020) -> Trading 212 (2020-21) -> Hopper Scala backend (2021-23) -> DraftKings senior backend (2025-). The pivot from Java to Scala at Hopper and the move into a US remote role suggest a deliberate shift toward functional/typed backend systems at scale.2025
