Rockstar🎓
Top SchoolRavaka Razafimanantsoa is an architect and engineering lead based in Tokyo with 11 years of experience building cloud-native web services and resilient microservice platforms. At Porters he designs and operates event-driven and REST microservices, led a migration of an in-house AI system to a scalable Redis-synchronized architecture, and enabled multiple daily releases through CI/CD and automation. A hands-on polyglot, he is the go-to expert for Typescript/Node, React, Python, AWS, Kubernetes and GitHub Actions, but also contributes to notable open-source projects like Home Assistant (SwitchBot integration). He combines strategic system design with developer-focused tooling—turning weeks-long batch efforts into one-day event-driven processes and empowering business users with internal apps and observability. Holding a Master’s in AI, he continually explores side projects that blend crawling, automation and product thinking—most recently a dynamic deal-clone that automates offer sourcing. Colleagues know him for mixing deep technical rigor with practical product impact and a persistent curiosity for new technologies.
