What I'm looking for

I’m looking for remote, B2B (and relocation) work where I can own backend services end-to-end—designing distributed, event-driven systems with strong reliability, idempotency, and failure recovery, and building production-ready integrations and transactional flows.

I’m a senior backend engineer with 20+ years of experience—15 years in .NET and 6 years in Scala—focused on distributed systems, event-driven architecture, and functional programming. I build reliable systems for external integrations and transactional flows, with a strong emphasis on consistency, idempotency, and failure recovery.

I own systems end-to-end: system design, defining APIs and data flows, and supporting production operations. Recently, I built real-time processing and payment services with Kafka-based asynchronous workflows, designed sub-2-second task scheduling, and implemented resilient reprocessing/recovery for failed or delayed operations—supported by observability and logging to trace complex distributed workflows.
