🔐 Security Engineer | 🛡️ Cloud Security | ⚙️ Backend & Systems Builder

I break systems deliberately
so they fail safely.

Security-first engineer with backend and systems focus.
No checkbox security — attack-aware engineering.

If a system can be abused, it will be.
Design for adversarial conditions.

• Offensive security
• Defensive engineering
• Backend & infrastructure

• 🔐 Security is baseline
• 🧠 Threat models > tools
• 🧪 PoC without mitigation is useless
• 🏗️ Systems must fail safely
• 🤖 AI without security is risk

Attackers think in possibilities
Defenders think in guarantees
I train myself to think like both

Secure systems aren’t built by understanding failure
