> Senior Software Engineer | Product-Focused Backend | Distributed Systems, Data Pipelines & Personalization

Location: Seattle, Washington, United States
Profile: https://flows.cv/mariaarbuzova

I’m a product-minded software engineer with 10+ years of experience building scalable systems that shape user experience and behavior. 

My work sits at the intersection of backend engineering, data, and product strategy, where I design the infrastructure behind search, discovery, and personalization. At Eventbrite, I led backend engineering for core search and discovery during a full app redesign, owning initiatives across ranking, recommendations, experimentation, and ML integrations. I focus on building systems that improve relevance, increase content diversity, and create adaptive, real-time user experiences.

I think in systems, not just services, using architecture as a lever for product direction and feedback loops for continuous learning. I’ve built and scaled distributed systems across AWS using tools like Airflow, Kafka, OpenSearch, and Lambda, while also driving stronger team practices through clear documentation, on-call standardization, and cross-functional alignment. I’m now looking to step into roles where I can influence product and technical direction at a deeper level—especially in areas like personalization, data platforms, and intelligent systems where infrastructure and human experience meet.
