Engineering Profile

Bridging core Linux infrastructure with modern software engineering principles.

Systems-Minded Software Engineer

I am a Computer Science undergraduate at Maharashtra Institute of Technology (Class of 2027) with an academic foundation built on a 3-year Diploma in Computer Engineering.

Rather than viewing software as isolated code in an editor, I focus on how applications interact with the host OS, the kernel, container runtimes, and the underlying network. As an RHCSA certified administrator and Red Hat Certified Cloud-native Developer, I bring real hands-on experience running and securing Linux workloads.

My toolkit combines Bash and Ansible for automation, Python and SQL for application logic and data modeling, Docker and Podman for containerized isolation, and Wireshark with TCP/IP for network-level diagnostics.

“Reliable software requires an intimate respect for the environment it runs in — from kernel parameters and user permissions to network sockets and container namespaces.”

RHEL & Systems Administration

RHCSA certified with practical lab depth across RHEL 9.x: SELinux policies, Firewalld configurations, systemd services, LVM storage, and SSH hardening.

Automation & Scripting

Practical automation using Bash shell scripts and Ansible playbooks for user management, system auditing, reproducible environments, and scheduled task pipelines.

Containers & Cloud-Native

Certified in cloud-native applications with DO188. Hands-on deployment of rootless container pods, custom bridge networking, persistent volume mounts, and Podman tooling.

Software & Problem Solving

Undergraduate Computer Science studies blending fundamental data structures, algorithms, Python programming, and SQL database models with systems-level understanding.
