01. Focus
Configuration

I come from a software development background, but increasingly approach systems from a security and reliability perspective. I care about how software behaves under stress, misuse, or failure, not just when everything goes as planned.

Environment
  • Editor: Neovim
  • OS: Linux / macOS
  • Shell: Zsh
  • Workflow: Keyboard-first
Process

I try to understand how a system is meant to work before analyzing how it breaks. I move between building features and analyzing signals, logs, and behavior across the system lifecycle.

Architecture

I am drawn to architectures that are observable and explainable, with clear boundaries, predictable behavior, and the ability to reason about what is happening inside the system.

02. Experience

Cyber Security Analyst

Dec 2024 — Jul 2026
KoçSistem · SOC

Working in a 24/7 SOC environment, focused on investigating and triaging security alerts using SIEM and EDR platforms. Daily work involves analyzing logs across network, endpoint, and identity layers to understand whether observed behavior represents real threats or operational anomalies.

This role provides direct exposure to how attacks, misconfigurations, and failures actually surface in production systems; shaping a more realistic understanding of system reliability and visibility.

Mobile / Backend Developer

Apr 2023 — Aug 2024
Vancy · Berlin (Remote)

Contributed to a production mobile application as part of a distributed team, working remotely with a Berlin-based company. Responsibilities spanned mobile development with React Native, backend services with Node.js, and integration with cloud infrastructure.

This experience built a strong foundation in shipping software used by real users, understanding operational trade-offs, and maintaining systems over time rather than treating development as one-off delivery.

System Flow
Ubuntu VPS->WireGuard->FastAPI->Peer ops

Built end to end: Ansible provisioning, FastAPI peer operations, firewall/DNS policy, dashboard, and visibility for day-two operations.

  • Single playbook hardens and provisions the gateway.
  • Admin surface stays behind the VPN interface.
  • Peer lifecycle covers keys, IPs, configs, and QR export.
  • Health, traffic, WireGuard, and SSH signals are visible.
