Top SchoolViktor Markvardt is a Senior Software Engineer with nine years of experience building high-performance backend systems, specializing in C++, Go, and Node.js across blockchain, iGaming, and automotive domains. He has designed and optimized core blockchain nodes, SDKs, and low-latency REST/WebSocket services, reducing API latency and improving uptime in production-grade networks. Viktor blends systems-level C++ expertise with modern Go microservices and TypeScript APIs, and has hands-on experience with cross-compilation, distributed networking, and large NoSQL performance tuning. At ProximaX he shipped developer tooling and SDK improvements that accelerated onboarding and cut testnet issues, while at his current role he focuses on global traffic routing, VPN-based connectivity, and real-time proxying for geographically distributed players. Comfortable mentoring teams and improving CI/CD workflows, he seeks backend roles where long-term performance, scalability, and clear documentation are priorities. An uncommon strength is his track record of applying embedded- and automotive-grade optimizations to cloud services, bringing a low-level performance mindset to large-scale distributed systems.
