Domain-to-spec execution
I organize business rules, status transitions, access roles, and reporting needs before turning them into backend behavior.
Profile
Cloud-Native Backend Engineer
I work where backend implementation meets cloud infrastructure: Java/Spring Boot services, data flow integrity, Kubernetes-oriented deployment, and Azure/AWS platform foundations. My background in product planning and technical writing helps me turn ambiguous domain requirements into clear system behavior, implementation notes, and operating documentation.
Current Focus
- Containerized backend services and platform operations
- Secure enterprise data flows, RBAC, auditability, and reporting
- Infrastructure automation with Terraform, GitHub Actions, and cloud-native deployment patterns
Reliability before decoration
I pay attention to data consistency, network boundaries, least privilege, repeatable deployment, and operational handoff.
Documented collaboration
I write implementation notes, manuals, and decision records so requirements and operations do not depend on memory.
Experience
Work shaped around backend systems and operations
Enterprise backend implementation
Built Java/Spring Boot features for EV charging monitoring, public parking reservation, and information systems, including RBAC, notification workflows, MyBatis Dynamic SQL, payment/refund states, reports, and security remediation.
Azure secure infrastructure design
Designed multi-region Azure infrastructure with VMSS, Application Gateway, Bastion, VNet Peering, VPN Gateway, Azure SQL, and Cosmos DB while tracking NSG, firewall, and Private Endpoint tradeoffs.
Serverless data pipeline
Built Daily Compass around Azure Functions, Cosmos DB, Static Web Apps, Node.js crawling, and a proxy flow that resolved browser security and frontend-backend communication issues.
Technical communication
Produced technical articles, PRDs, workflow diagrams, manuals, and operating notes across engineering, product, and editorial roles.
