I currently work as a Technical Architect, Lead Software Engineer, and AI Engineer, with strong experience in Spring Boot and building scalable applications. I’ve worked remotely with teams and clients across the US, UK, Australia, and New Zealand, which has given me the opportunity to work with different teams, technologies, and business environments.
