Rockstar🎓
Top SchoolSaša Šijak is a versatile software engineer with a decade of experience building full-stack systems, from high-traffic backend platforms to polished React front-ends. He’s worked across industries—gaming, betting, blockchain, and enterprise—delivering scalable services, integrations, and user-facing apps while avoiding lock-in to any single tech stack. Notable work includes contributing front-end improvements to OffchainLabs’ Arbitrum token bridge and implementing major DApp and enterprise sites as a Toptal contractor. Driven by curiosity since childhood (he taught himself the Latin alphabet to play on a Commodore 64), he enjoys solving real problems, learning new tools, and shipping pragmatic solutions. Comfortable leading teams and shipping solo, he pairs deep backend experience (Java, Kotlin, Python, messaging systems) with modern frontend craft (React, TypeScript, Tailwind/Chakra) and a long history of production deployments.
