Summary
👤
Senior🎓
Top SchoolYutaro Doi is a senior software engineer and technical leader with 12 years’ experience building scalable backend and search platforms across multinational, English-speaking teams. He consistently takes end-to-end ownership—from requirements and system design to implementation, deployment, and operation—while bridging frontend, infrastructure, and product domains. At Mercari he drives architecture and performance optimization for a group-wide search platform used across multiple services, and previously led a large domain decomposition effort at freee to turn a monolithic accounting system into maintainable services. He routinely mentors engineers, influences company-wide technical standards (including OpenAPI conventions), and participates in hiring and evaluation as a playing manager. Comfortable steering technical discussions with distributed stakeholders, he pairs hands-on coding with pragmatic architectural leadership. An uncommon strength is his political-economy academic background, which informs his ability to align technical decisions with broader business and organizational trade-offs.
