Zalim Bashorov is a seasoned compiler engineer and team lead with 14 years at JetBrains, currently driving Kotlin/Wasm and Kotlin/JS backend work from the Netherlands. He combines hands-on contributions to the official Kotlin repository—improving IR, JS backend sourcemaps and DCE optimization—with leadership responsibilities in design, planning, hiring and process optimization. Comfortable across VMs, compilers and interpreters, he has led the creation of a new Kotlin compiler backend and advocated for WebAssembly as a compilation target. Colleagues rely on him for both deep technical refactors and pragmatic team coordination, having stepped in repeatedly as de facto manager and recruiter. His academic background in applied mathematics and physics underpins a methodical approach to incremental compilation and complex compiler infrastructure. Outside of JetBrains he’s involved in emerging wasm-focused efforts, signaling continued focus on cross-platform language tooling.
