Profile

Principal-grade engineer. I design and run resilient cloud services: DBaaS for Postgres and Redis, Managed RabbitMQ, voice and real-time systems on Go and gRPC, event-driven integrations on Kafka, business-process orchestration on Temporal.

I run architecture reviews, set engineering standards and DevEx practices at the unit level, mentor engineers in the internal mentoring program. I adapt AI tooling to the team’s workflow: custom skills and subagents, MCP servers wired to internal systems, guidelines and prompt templates tuned to the domain.
