What I'm looking for

I'm looking for backend or platform engineering roles on product teams that own domain-heavy systems end to end, using .NET Core or Golang and distributed services on Kubernetes. I'm open to remote or Taiwan-based opportunities.

I've built .NET Core backends for Cafler's Taiwan-market expansion, including a multi-tenant Client-360 CRM, LINE customer-channel integrations, payment and e-invoicing workflows, and checkout protections that prevent duplicate charges.

At Duotify Tech, I split a credit-loan monolith into 10+ microservices, built Oracle Cloud infrastructure, and introduced a lighter spec-driven workflow adopted across 3–4 projects. Earlier at TitanSoft, I worked on payment processing and third-party integrations, improved Kubernetes monitoring with ELK, and led a 4–6 person intern team as Scrum Master.

Outside work, I write Golang, .NET, and share Tech articles at Coding Afternoon, publish open source including the EccSDK NuGet package, and build applied-cryptography and on-chain risk-analysis projects.
