What I'm looking for

I'm looking to lead backend and platform work where I can design scalable distributed systems, secure cloud infrastructure, reliable production workflows, and controlled AI/LLM capabilities.

I'm leading backend and platform engineering at Volga Partners, owning architecture, cloud infrastructure, security, production releases, and reliability for scalable systems. I build Node.js and NestJS services with PostgreSQL, Redis, queues, event-driven workflows, and secure AWS infrastructure.

Previously, I modernized monolithic services at Ninjas Code and improved data retrieval performance by approximately 60% through Redis caching and database optimization. I've also led backend delivery, payment integrations, CI/CD deployments, and production troubleshooting at TechXpert, while contributing OpenTelemetry observability instrumentation to PilotSwarm.
