Description

I am a freelance Network & Cybersecurity Engineer with over 7 years of hands-on experience working across enterprise, cloud, and hybrid environments. I help startups and growing companies design, secure, and maintain reliable network and security architectures that support business growth without unnecessary complexity.

My core expertise includes enterprise firewalls such as Palo Alto, FortiGate, and Check Point, along with VPN technologies (IPSec and SSL), routing (including BGP), and advanced network troubleshooting. I have worked extensively on firewall policy design, NAT, secure access, traffic segmentation, and resolving production issues where availability and security are equally critical.

I also specialize in cloud networking and security on Azure and AWS. My experience covers virtual networks and VPCs, subnet design, routing tables, security groups, firewall integration, and secure site-to-site and remote access connectivity. I support both cloud migrations and optimization of existing environments with a strong focus on security and stability.

My approach to cybersecurity is practical and implementation-focused. I work on real-world challenges such as securing internet-facing services, hardening firewall configurations, improving VPN reliability, and quickly troubleshooting network incidents that impact business operations.

I am comfortable working independently or collaborating with internal IT, DevOps, and engineering teams. I adapt quickly to new environments and can deliver value with minimal onboarding, which makes me well-suited for startups and fast-moving teams.

I am available for remote, freelance, and project-based engagements, supporting short-term or mid-term assignments. My goal is to deliver secure, scalable, and easy-to-maintain solutions while communicating clearly with both technical and non-technical stakeholders.
