Summary
👤
Senior🎓
Top SchoolIgor Grishin is a senior software engineer based in Berlin with 11 years of experience building reliable, high-throughput backend systems primarily in Go and Java. At Vivid Money he architects and implements payment, transfer and crypto onboarding services using Go, Kafka, Postgres/DynamoDB and gRPC, and has authored several shared internal libraries for scheduling, retrying Kafka consumers, tracing and DLQ handling. His earlier career focused on resilient, enterprise-grade Java systems—designing service-to-service DTO libraries, Spring-based observability/autoconfiguration tooling, and real-time market data providers—experience that surfaces in his pragmatic approach to integrations and operational robustness. He combines deep systems-level knowledge (even prototyping a kernel module) with hands-on delivery and mentoring, and is comfortable owning the full lifecycle from protocol-level TCP/UDP data ingestion to cloud-native deployments. Notably, he blends a finance-focused domain background with strong open-source and tooling instincts that improve developer productivity and system reliability.
