Message

At Bank Alfalah, I design, implement, and monitor enterprise-wide network security infrastructure, using Infrastructure as Code methods to streamline secure network configurations.

I manage Cisco ASA, FTD, and FMC appliances, and administer Palo Alto firewalls with security policies, SSL decryption, app-ID control, and VPN provisioning.

I also secure and load-balance banking applications with F5 BIG-IP, and monitor network threats through SIEM integration, log analysis, and the ELK stack.

Earlier at Bank Alfalah, I monitored and maintained WAN/LAN infrastructure supporting branches and remote locations across Pakistan. In internships, I developed blockchain applications and backend APIs, and created Python automation for internal workflows and network devices.
