Updated
•8 min readP
🔹 About Me I am an Engineer with 2+ years of experience in Software,python automation,linux server and Networking at Tata Communications. Currently, I am transitioning my career into DevOps and Site Reliability Engineering (SRE) with hands-on knowledge of Docker, Ansible, Jenkins, Git, CI/CD pipelines, and AWS Cloud. Key contributions include automating data gathering using Python (Selenium), developing and maintaining web portals with Django and PHP, and managing Linux server environments (Red Hat Enterprise Linux 8.7). My networking expertise spans complex troubleshooting and configuration of routers and switches (Juniper, Cisco, Huawei), with hands-on experience in routing protocols (OSPF, BGP), VLANs, MPLS, VPN, and SD-WAN technologies. I am passionate about automation, cloud infrastructure, and reliability engineering, and I am actively seeking DevOps / Site Reliability Engineer opportunities where I can contribute, learn, and grow. 📌 Skills: AWS | Docker | Ansible | Jenkins | Git | CI/CD | Linux | Python | Networking | Fortinet | 📌 Certifications: CCNA Cisco Fortinet Firewall NSE4 AWS Cloud Practitioner Certification Devops skillsup from GFG
