Network Engineer & Software Engineer

I build the paths data travels on — and the software that rides them.

[HOP 02]/whoami

Two layers, one engineer.

tty1 — visitor@muhayara~/whoami

$ whoami --verbose

Informatics student who lives on both sides of the stack. On the network side I design multi-subnet topologies, write ACLs, map ports with Nmap and keep a Zabbix-monitored homelab alive on Ubuntu Server.

On the software side I build Telegram bots with a Handler-Service-Repository architecture, fullstack PHP apps with OAuth 2.0, React + AI experiments, and ESP32 robots that talk MQTT in real time.

I care about the moment a packet leaves one system and safely arrives in another, that is where networks and software meet.

[HOP 03]/stack

The stack, layer by layer.

Every packet is wrapped and unwrapped through seven layers. So are my skills — from ESP32 pins up to REST APIs.
