Resume

Hello, I’m BBACK.
My work has increasingly focused on backend engineering, system design, operations automation, data processing, and building services that remain reliable in production.

This page is a public-facing resume summary focused on career overview and technical strengths, without including sensitive internal project details.

Profile

Summary

I started from mobile application development and gradually moved toward backend systems, platform engineering, infrastructure operations, and automation.

My strengths are centered around areas such as:

  • backend design for large-scale data environments
  • microservice architecture and service operations
  • CI/CD automation and DevOps workflows
  • Kubernetes / AWS-based infrastructure operations
  • authentication, API gateway, and data pipeline design
  • system improvements focused on reliability, scalability, and operational efficiency

I tend to think beyond implementation itself and focus on how a system should be designed to remain maintainable and stable in real production environments.
