Hey! I'm Yehezkiel

I'm a Cyber Security Professional specializing in Network and Web Application Penetration Testing with experience in doing Pentest to 20+ Production Web Application. I conduct VAPT engagements using Burp Suite, Nmap, SQLMap, and OWASP Top 10 methodology, with additional experience in SIEM (Wazuh), IDS (Snort), Honeypot analysis, and Malware analysis. I bring a builder's perspective to security work from hands-on experience architecting production-grade distributed systems in Go, gRPC, Redis, and Kubernetes — understanding vulnerabilities from both the attacker's and the engineer's side. I also occasionally architect AI/ML engineering spanning pattern analysis, forecasting, RAG, and Computer Vision.
