About this gig

Stop gambling with amateur code. Build with government-grade security and scalability.


Hi, Im Leo. I am a Full-cycle Software Engineer who doesn't just write codeI build engines that power nations and businesses.


Why Trust Me? I currently build and maintain the official Indonesia e-Visa & Stay Permit System. I handle complex Cross-Border APIs, secure admin verification workflows, and high-traffic databases. If I can secure national data, I can secure your business.

Beyond enterprise systems, I am a SaaS founder. I built and launched mrakdon.com and slnk.me, so I understand the full product lifecyclefrom the first line of code to the final user experience.


My Services:

  • Custom SaaS Development: Turn your idea into a functioning MVP or full product.
  • Secure API Architecture: Node.js backends that are fast, scalable, and secure.
  • Complex Web Applications: Compliance systems, dashboards, and automated workflows.
  • Bug Fixing & Optimization: I troubleshoot hardware/software logic to keep systems running smoothly.

My Approach: I combine scientific analytical thinking with practical engineering. I don't just "patch" issues; I solve them at the root.
