Geison Biazus is a Senior Backend Engineer from Paraná, Brazil with over a decade of hands-on experience designing and operating scalable, multi-tenant systems across mobility, marketing automation, and fintech domains. He has driven high-throughput services in TypeScript, Elixir, Ruby, Go and Python—building systems that handle thousands of concurrent connections and tens of thousands of requests per minute. At Wunder Mobility and RD Station he led architecture and test-quality improvements, migrating legacy apps to hexagonal and multi-tenant designs while raising test coverage and introducing TDD and clean-architecture practices. Comfortable across cloud-native platforms (Kubernetes, GCP, AWS) and a wide data stack (Postgres, Redis, Elasticsearch, Neo4j), he blends pragmatic engineering with coaching and team enablement. Notably, he has repeatedly converted B2C products into robust B2B multi-tenant services, a pattern that surfaces his focus on operational stability and real-world scalability.
