// About

Engineering software that matters

I am a Fullstack Software Engineer and DevSecOps Engineer with over 8 years of professional experience building and operating software in the banking, fintech, payment, and enterprise sectors.

My work spans the full software lifecycle — from writing backend microservices and frontend dashboards to configuring CI/CD pipelines, managing infrastructure, and supporting vulnerability remediation across production environments.

At PT Bank Mandiri, one of Indonesia's largest state-owned banks, I have contributed to mission-critical systems including dispute management, national clearing (SKN), RTGS, telegraphic transfer, tax collection, and ATM/CRM monitoring platforms.

I work with engineering discipline — feature branch isolation, code review, automated builds, dependency audits, penetration testing support, and reproducible deployments across DC and DRC environments.

// Engineering Discipline

DevSecOps Workflow

Delivery discipline applied consistently — from local development to production deployment.

Engineering practices

  • 01Feature branch isolation
  • 02Code review readiness
  • 03Build validation before merge
  • 04Dependency and vulnerability checks
  • 05CI/CD automation
  • 06Secure access and authentication integration
  • 07Environment-aware configuration
  • 08Production readiness checks
  • 09Penetration testing and vulnerability remediation support
  • 10Performance testing before production release
  • 11Deployment discipline across DC/DRC or cloud environments
  • 12Monitoring and troubleshooting readiness
  • 13Clear documentation and reproducible commands

Sample workflow

bash — feature/example-branch
1git status
2git checkout feature/example-branch
3npm install
4npm audit --audit-level=high
5npm run lint
6npm test
7npm run build
8codegraph sync .
9git add .
10git commit -m "feat: implement production-ready feature"
11git push origin feature/example-branch

Every commit on production-bound systems goes through audit, lint, test, and build validation before merge. Deployments are environment-aware and follow DC/DRC readiness checklists.
