Senior Software Engineer
Meitou Inc.
Owning backend architecture and delivery for a financial technology platform, improving release workflows, and introducing practical AI tooling into engineering work.
About
Backend depth.
Product perspective.
I'm a senior backend engineer who has spent more than a decade designing distributed systems, modernizing platforms, and guiding teams through high-stakes delivery.
MQ
I care about systems that are understandable under pressure—not just impressive on a diagram.
Work with me ↗My work sits at the intersection of scale, reliability, and engineering leadership.
I have built systems across fintech, social platforms, automotive IoT, e-commerce, and local services. The domains changed; the core challenge did not: make complex behavior predictable, measurable, and easier for a team to evolve.
My strongest tools are Java and the Spring ecosystem, backed by event-driven architecture, distributed data systems, and a pragmatic approach to cloud operations. I also use TypeScript and Python when the problem calls for them.
Today I'm especially interested in the overlap between backend engineering and applied AI—using agents and automation to improve development workflows without giving up review, safety, or technical judgment.
Experience
A decade of building and leading.
