What I'm looking for

I'm looking to focus on core backend engineering, database optimization, distributed systems, and cloud-native architecture.

I've built enterprise platforms for Bidmatic, EasySoftGroup, and independent clients, from an AI-assisted video engine processing 1,000+ videos daily to a real-time hotel operations platform.

At Bidmatic, I architected NestJS microservices, PostgreSQL rendering queues, RabbitMQ and Redis infrastructure, and Kubernetes deployments for global tier-1 publishers. I also built programmatic advertising and streaming products, improving asset loading times by up to 10x and reducing production regressions by over 30% through a TypeScript migration.

I'm now focused on core backend engineering, database optimization, distributed systems, and cloud-native architecture.
