What I'm looking for

I’m looking for a senior solution-architecture role where I can design secure, scalable microservices on AWS/GCP, lead teams, and improve reliability and performance through automation, observability, and pragmatic engineering decisions.

I’m a results-driven solution architect with over 12 years of experience building Go/Gin-Echo scalable, high-performance web systems. My expertise spans Go, Python, and PHP frameworks, and I focus on designing systems that stay fast, secure, and reliable as traffic grows.

I’ve developed complex APIs, backend services, and microservices used by thousands of users. Notable impacts include improving performance and reliability through caching and load-balancing, reducing operational overhead via automation and containerization, and strengthening security with IAM, VPC isolation, and CIS benchmarks.

At Jan Japan (Senior Solution Architect, 2019–Present), I scaled and optimized backend systems across operations in 22 countries. I built a Python-based AI bidding predictor, automated auction & logistics workflows, and led a team of 5 programmers—while also traveling internationally to implement solutions and train local teams.

I enjoy turning ambiguous requirements into production-ready architectures—distributed systems, event-driven designs, and cloud-native platforms on AWS and Google Cloud. I’m especially motivated by system design, performance tuning, and observability that translate directly into measurable business outcomes.
