🚀 What I'm Building Right Now

🌐 Private 5G Network (with SLTMobitel)

Running a production 5G edge network with User Plane Functions on Raspberry Pi. Yes, 5G. On a Pi. At the edge.

Raspberry Pi Kubernetes SDN Open vSwitch 5G Core

☁️ Cloud-Native Platform with Auto-Recovery

Built a Kubernetes platform where systems heal themselves. Containers crash? Auto-restart. Database fails? Automatic failover. Everything monitored in real-time with Prometheus & Grafana.

🤖 P-E-BO - AI Desk Companion

🏆 IESL Top 10 Finalist | 🥉 3rd Place ICIIS 2025

Built the mobile app and AWS deployment for an AI desk companion with 7-emotion detection (95% accuracy) and Gemini AI voice interaction.

💡 The Interesting Bits

🎯 I Run Systems That Could Fail 5G network functions on edge devices Kubernetes clusters with auto-recovery Production monitoring systems Real-time traffic analysis pipelines The goal? Make them unbreakable.

🔥 Then I Break Them Inject network failures Simulate edge node crashes Test recovery mechanisms Measure MTTR (Mean Time To Recovery) Why? You don't know your system until it fails.

📊 How I Approach Engineering

step_1_deploy:
  what: "Build something real, not a toy"
  example: "5G network on actual hardware, not a simulator"

step_2_observe:
  what: "Instrument everything"
  tools: "Prometheus metrics, Grafana dashboards, packet captures"

step_3_break:
  what: "Chaos engineering, but on purpose"
  why: "If you haven't seen it fail, you don't understand it"

step_4_fix:
  what: "Auto-recovery, not manual fixes"
  goal: "System heals itself faster than you can SSH in"

step_5_document:
  what: "Write it down, share it"
  output: "Runbooks, dashboards, blog posts"

⚡ Fun Fact

I believe the best way to learn networking is to deploy 5G on a Raspberry Pi,
the best way to learn Kubernetes is to watch it auto-recover from failures,
and the best way to learn reliability is to teach 40 students who ask "why?" constantly.

✨ Deploy • Observe • Break • Fix • Repeat ✨
