Senior🎓
Top SchoolAndrew Hanasiro is a Software Engineer based in São Paulo with nine years building full-stack and cloud-native systems across startups and scale-ups. He has led technical teams and roadmaps, created knowledge bases and deployment processes, and improved operational agility using frameworks like Adonis and Next. His background spans frontend pricing engines, Scala/ZIO and hexagonal architectures, Kafka, GCP and AWS services, plus hands-on DevOps with Docker/Kubernetes and CI/CD. He mentors junior engineers, runs 1:1s and structures onboarding and developer culture, reflecting strong people-first technical leadership. Comfortable switching between building notifications integrations, observability, and backend data systems, he’s also learning DevOps formally while shipping production services. Not obvious from titles: he has repeatedly owned both architecture and day-to-day support, bridging strategic design with customer-facing operational fixes.
