Building, breaking, and understanding systems.

B.Tech student drawn to Linux, networking, and the infrastructure that keeps services alive after dark.

Who lurks here

I’m a B.Tech student who learns by building: configuring servers, running my own infrastructure, and fixing whatever breaks along the way.

I care more about how things work than about simply using them. I like Linux, self-hosted and open-source tools, and the path a request takes from the internet to a server.

Right now I’m working through networking fundamentals, C++ and problem solving, and deeper Linux and DevOps practice.

The Grimoire

Homelab

Infrastructure

A self-hosted Linux server that runs my game server infrastructure, and where I practise administration, reverse proxies and remote access.

Pterodactyl Panel and a Pelican Panel fork managing several Minecraft instances.
Cloudflare in front, a static public IPv4 address, and reverse proxy configuration.
Worked through CGNAT, port forwarding, Cloudflare Tunnels and secure remote access.
Memory and resource management, plus troubleshooting network and server problems.

Ubuntu · Nginx · Cloudflare · Pterodactyl · Pelican · WireGuard · SSH

Minecraft network

Networking

A multi-server Minecraft network with Survival and Bedwars modes, built around a Velocity proxy.

Connected backend servers through Velocity and handled player login with LibreLogin and MySQL.
Hid backend server IPs behind TCPShield and Cloudflare, and tried Cloudflare Spectrum.
Debugged connectivity and latency problems across the network.

PointBlank club website

Web development

Worked on the PointBlank club website, including a CRUD interface for managing event information.

Next.js · React · JavaScript

Bluetooth RC grass cutter

Hardware

An Arduino-controlled vehicle driven from a phone over Bluetooth, with speed control and a relay switching the cutter motor on and off.

Wired a motor driver, four geared motors and a relay, and gave the cutter its own 12V battery.
Wrote the control program and handled the power wiring.

Flask video downloader

Backend

A small web app that takes a link and downloads the video, served with Gunicorn. Most of the work went into request handling and fixing cookie problems.

Currently brewing

Networking and CCNA

In the cauldron

Working through a structured course alongside the Cisco CCNA 200-301 syllabus: routing, switching, VLANs and troubleshooting. Not certified yet.

C++ and problem solving

In the cauldron

Arrays, strings, recursion, STL, basic number theory and complexity, working towards Codeforces-style problems.

Linux and DevOps

In the cauldron

Going deeper on server administration, Docker and automation.
