Rockstar🎓
Top SchoolAndrew Volozhanin is a Senior Software Engineer with 11 years of experience building scalable, production-grade systems across fintech, marketplace, and CRM domains. Based in Haarlem, he has led impactful migrations and architecture work at Catawiki—rewriting search with deep Elasticsearch knowledge, introducing ImgProxy for image processing, and helping deprecate a legacy monolith in favor of Kafka-backed microservices. Previously he built PSD2-compliant fintech APIs, tackled large-scale data and file volumes, introduced Elixir and Elm at his company, and established CI/CD, code review, and observability practices. Comfortable across PostgreSQL, Redis, ClickHouse, InfluxDB, Elasticsearch and more, he blends pragmatic engineering with stakeholder collaboration to preserve user experience during major changes. He mentors junior engineers and fosters productive architecture discussions and documentation, bringing both hands-on coding and team-level craft to delivery. Less obvious: he pairs a practical tool-for-the-job mindset with a history of introducing new languages and operational practices to improve long-term engineering health.
