Enterprise Security Monitoring Platform
Multi-SIEM production platform: Splunk Enterprise + Wazuh XDR + Elastic Fleet + Security Onion on Proxmox VE. 500+ endpoints, 100+ servers, <2 min MTTN.
View Case Study →SOC Analyst & SIEM Engineer at PostEx (Fintech) — building and operating enterprise security monitoring infrastructure using Splunk Enterprise, Wazuh, Elastic Fleet, and Security Onion across 100+ servers and 500+ endpoints. Detection engineer with 40+ MITRE ATT&CK-mapped rules. TryHackMe Top 1%.
I’m a SOC Analyst & SIEM Engineer (titled Assistant Manager – Data Center) at PostEx, a high-volume fintech and logistics company in Lahore, Pakistan. Over the past 3+ years I’ve designed, deployed, and operated the full enterprise security monitoring stack — from initial log ingestion to detection rule engineering and incident response.
My daily work involves operating a multi-SIEM environment: Splunk Enterprise for log aggregation and SPL-based detection, Wazuh for XDR/HIDS across 500+ endpoints, and Elastic Fleet with Elastic Defend for EDR across 100+ cross-platform servers. I’ve built 40+ MITRE ATT&CK-mapped detection rules and reduced false positive rates by 40% through systematic tuning.
Beyond SIEM work, I design network security architecture, manage MikroTik and Cisco infrastructure, run vulnerability assessments using OpenVAS and Nmap, and conduct web application security testing. I’m a TryHackMe Top 1% ranked practitioner and actively practice offensive security skills.
