About Me

Building My Future in Cloud & Networking

I hold CCNA for enterprise networking and network security, RHCSA for Linux systems administration, and AWS Cloud Practitioner for cloud fundamentals. Beyond the certs, I've built a full-stack AWS deployment covering VPC networking, load-balanced EC2, RDS, serverless automation with Lambda/SNS/SQS, CloudFront delivery and CloudFormation IaC.

Alongside that, I've designed multi-router enterprise networks in Cisco Packet Tracer and hardened RHEL servers with SELinux and Firewalld — and I bring 4+ years of admin and IT support experience from Omtech Computer Education, where I supervised staff, managed records and supported desktops, LAN/Wi-Fi and user access.

My goal is to combine that operational discipline with hands-on technical skill and build a career in Network, Cloud and Linux Administration.
