I implement AI solutions that actually work — custom integrations, smart automations, and intelligent systems built precisely to your needs.
Cologne, Germany
I build things that work — then make them smarter with AI.
I'm a Cyber Security student and developer based in Cologne with a strong foundation across AI integration, automation engineering, secure software development, and data science. I speak four languages fluently — which means I build for your market, not just your stack.
I bring the same discipline and precision to code that I apply to everything else. Whether it's an LLM integration, an n8n automation pipeline, a full-stack web app, or a security audit — I deliver with care, reliability, and technical depth.

What I build for you
Technical depth meets clear communication. Every solution is built to your exact spec — no templates, no shortcuts.
AI Automation
Eliminate manual work with intelligent pipelines. I build custom automations using n8n, Make, and Python — triggered by AI, tailored to your workflow.
LLM Integration
Embed AI directly into your product. I integrate OpenAI, Claude, and Gemini APIs — including RAG pipelines, semantic search, fine-tuning, and prompt engineering.
AI Chatbots
Custom chatbots trained on your data — your docs, your tone, your rules. CRM-connected, multilingual, always on. Not another generic widget.
AI Strategy
Not sure where AI fits in your business? I audit your workflows, map the highest-leverage opportunities, and deliver a concrete implementation roadmap.
Why me — not a big AI agency?
Agencies are expensive, slow, and impersonal. You deserve a partner who actually thinks.
What I've built
Real tools. Real code. Security-oriented projects built from scratch.
Port Scanner CLI
Scans a target IP for open ports (1–1024), detects service names, and outputs a formatted security report using parallel threads.
$ python port_scanner.py 192.168.1.1 Port Scanner — Mesut Ziel: 192.168.1.1 | Bereich: 1–1024 ───────────────────────────────────── PORT STATUS DIENST 22 offen ssh 80 offen http 443 offen https 3306 offen mysql 8080 offen http-alt ───────────────────────────────────── 1024 Ports in 3,2 s gescannt 5 offene Ports gefunden
Caesar Cipher Tool
Interactive cryptography tool — enter a message, choose a shift value, encrypt or decrypt in real time.
> caesar("Hello World", 13)
"Uryyb Jbeyq"
> caesar("Uryyb Jbeyq", 13, true)
"Hello World"Password Strength Analyzer
Analyses password strength against entropy, character classes, and common patterns. Gives a scored breakdown of weaknesses.
> analyze("password123")
Score: 2/8 — Weak ⚠
Missing: uppercase, symbols
> analyze("T!ger$2024#kX")
Score: 8/8 — Very Strong ✓
Entropy: 42.3 bitsNetwork Traffic Logger
Raw packet sniffer in C++ using libpcap. Logs TCP/UDP traffic with source and destination IPs across a network interface.
$ sudo ./network_logger eth0 [*] Aufzeichnung auf: eth0 [TCP] 192.168.1.5:52341 -> 93.184.216.34:443 [TCP] 192.168.1.5:52342 -> 140.82.114.4:443 [UDP] 192.168.1.5:51234 -> 8.8.8.8:53 [TCP] 10.0.0.1:80 -> 192.168.1.5:49821 ^C [*] 4 Pakete erfasst | Gestoppt.
Brute Force Detector
Detects brute-force login attempts by analysing auth logs for repeated failed connections from the same IP.
$ python brute_force_detector.py auth.log [*] Analysiere: auth.log ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚠ ALARM: 185.220.101.47 Fehlgeschlagene Versuche: 23 in 60s Status: MARKIERT — BRUTE FORCE ⚠ ALARM: 45.33.32.156 Fehlgeschlagene Versuche: 8 in 45s Status: MARKIERT — BRUTE FORCE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 2 IPs markiert. Bericht gespeichert.
Multilingual Flashcard App
Spaced-repetition flashcard app with per-deck progress tracking and confidence-based card scheduling.
Stapel: Arabisch → Deutsch ───────────────────────────────── Karte 1/10: مرحبا → "Hallo" Karte 2/10: شكرا → "Danke" Karte 3/10: نعم → "Ja" Fortschritt: ████████░░ 80% Richtig: 8 / 10
JWT Decoder
Decodes JWT tokens client-side — splits header, payload, and signature and displays the raw claims.
$ python jwt_decoder.py <token>
Header:
{ "alg": "HS256", "typ": "JWT" }
Payload:
{ "sub": "1234567890",
"name": "Mesut",
"role": "admin",
"iat": 1716840000,
"exp": 1716926400 }
Signatur: SflKxwRJ... (nicht verifiziert)Subnet Calculator
Calculates subnet mask, broadcast address, first/last host, and usable host count from any CIDR notation.
$ python subnet.py 192.168.1.0/24 Netzwerk: 192.168.1.0 Subnetzmaske: 255.255.255.0 Broadcast: 192.168.1.255 Erster Host: 192.168.1.1 Letzter Host: 192.168.1.254 Nutzbare Hosts: 254
