At Money Forward X, I architected the foundational microservices design for MFX Data Platform, standardizing hexagonal architecture in Kotlin and Spring Boot for pluggable integrations across financial sectors.
I owned a shared financial-data service from product requirements through production, turning fragmented upstream data into 11+ standardized OpenAPI endpoints used across 10+ MFX products. I also built the queueing and observability core of a coroutine-native asynchronous job framework.
For Mikatano ID & Biz Billing, I built and operated production-critical Go services for identity and billing. I co-built a phased, zero-downtime rollout of a re-architected ID platform across 30+ banks.
Earlier, I built Cashflow Management from the ground up, integrating bank transaction data to provide cashflow visibility to 30K+ SMEs. I also supported the migration of a legacy Ruby on Rails monolith to distributed Go microservices for Cloud Accounting.
