Summary
👤
Senior🎓
Top SchoolViktor Kozlov is a Senior Software Engineer with a decade of experience building and operating high-throughput, microservices-based systems across e-commerce, gaming, and fintech domains. Currently at Zalando, he has led cross-team initiatives to improve fulfillment, modeled transport disruptions, and ensured smooth operation during peak CyberWeek traffic—work that blends hands-on design with pragmatic observability improvements. Comfortable across Node.js/TypeScript and Kotlin/Spring stacks, he favors single-responsibility design, extensive testing (often TDD), and making technically sound trade-offs between fast fixes and long-term solutions. He routinely mentors engineers, shapes requirements with product teams, and has a track record of shipping bespoke simulators, KYC integrations, and real-time data pipelines. Quietly persistent about tackling tech debt in spare minutes, he balances a willingness to go the extra mile on interesting projects with respect for personal time.
