Senior🎓
Top SchoolCarl Aaro is a System Architect with 12+ years building distributed systems, FinTech platforms and secure infrastructure, currently shaping backend architecture at Billogram in Uppsala. He specializes in Python-driven microservices, Docker/Kubernetes orchestration, AWS, messaging (RabbitMQ, SNS/SQS) and cryptographic security across payments and banking integrations. A practical full-stack engineer by trade, he pairs deep Linux and systems experience—including naval cryptography and TEMPEST work—with hands-on API, database and event-driven design. He’s been coding since age seven and brings a rare blend of long-term product ownership and low-level security discipline to complex financial systems. Outside work he pursues photography across travel, fashion and events, a creative outlet that complements his technical attention to detail.
