Christopher Domenicano

Software Engineer

I'm a Software Engineer and Team Lead with experience across Fortune 500 environments, fast-moving startups, and R&D. I work mostly with Java/Spring Boot and Node.js/TypeScript, focused on event-driven systems (Kafka, RabbitMQ, AWS Lambda/SQS), OAuth2 integrations, and high-throughput services. Recently contributed to shipping a €1M internal venture to production. In my spare time I really enjoy studying and reading technical books, alongside playing videogames and working on personal programming projects.
