Top SchoolViktor Penelski is a pragmatic Staff Software Engineer based in Sofia with 10 years of experience building highly available, distributed backend systems and platform infrastructure. He has driven platformization at Hyperscience—building a flexible workflow orchestration engine and SDK that turned a single use case into a horizontally scalable product—and excels at making complex systems observable and extensible for internal and external developers. Viktor’s background spans high-throughput Java microservices, Python backend development, and production-grade CI/CD and container orchestration, with hands-on experience across PostgreSQL, Kafka, S3 and Kubernetes. He pairs deep technical delivery with mentorship and clear knowledge-sharing, having taught Java and Spring Boot courses and produced developer-facing documentation and demos. A detail that stands out: he has repeatedly led zero-downtime migrations and performance improvements that reduced tail latency and sped up batch processing by an order of magnitude.
