Engineering Profile

I build practical systems, not only prototypes.

I am a Computer Science professional and technical builder focused on the intersection of artificial intelligence, cybersecurity, software engineering and DevSecOps.

I build practical systems rather than only prototypes — from AI applications and APIs to cybersecurity tools, automation platforms, websites, mobile applications and cloud-ready software.

My engineering approach

  • Secure-by-design development
  • Automation
  • Clean architecture
  • Practical problem solving
  • Continuous learning
  • Technical documentation
  • Deployment discipline

I am building SifunaCodex into a technology brand focused on intelligent, secure and automated digital systems.
