Offensive Security · Fullstack · Applied AI · Markets — Türkiye
I build systems that actually run. I work across offensive security, fullstack and edge engineering, applied AI, and market infrastructure, and I run IT operations at Fırat Group / BEQW Systems. This site is a system I designed and wrote from scratch and operate on my own.
fsahin.com — World Terminal
A real-time map terminal that watches the world from a single screen. No template, framework or page builder was used; the interface is hand-written and runs in production. It is served at /terminal.
The design has one rule: real data, honest failure. Every value on the screen resolves to a live source. When a source does not respond, the screen shows no fabricated value — the panel switches clearly to SIGNAL LOST. That is the design decision I care about most.
What is on the screen
Earthquakes and natural events — from official scientific sources, with their locations
Air traffic and orbital tracking — live position streams
Weather, air quality and space-weather indicators
Türkiye and world news feed — headlines link to their original publisher
Market indicators and network status
Visitor counter and visitor chat — real, not inflated
The third-party data shown in the terminal belongs to public scientific, governmental and publisher sources; each record's source is named inside the application, in its panel and in its popup, and news headlines link directly to their original publisher. This site does not own that content — it visualises it in its own original interface. Full texts are never copied.
Areas of work
Offensive security — penetration testing, vulnerability assessment, system hardening and security automation on Kali Linux; OSINT and reconnaissance. Authorized assessments only; technical details are withheld for operational security.
Fullstack and edge engineering — real-time interfaces, edge deployment on Cloudflare Workers, data visualization, production systems built without frameworks.
Applied AI — fully local, offline reasoning and retrieval systems; autonomous agent architectures; privacy-preserving design where no data leaves the machine.
Market infrastructure — systematic trading systems with risk control and validation discipline; architecture, strategy and parameters are private.
Data, automation and 3D production — large-archive processing, process automation, production pipelines and visualization.
