Enterprise IT experience. Security-focused development.
IT Support Specialist (Working Student) at Simon-Kucher in Cologne with more than four years of enterprise IT support experience across Germany and India. I have completed my BSc (Hons) Cyber Security and received the final result; the final degree certificate is currently pending. Available for full-time opportunities.
Target roles: IT Support Specialist, IT Support Engineer, Infrastructure Support Engineer, Junior Cybersecurity Analyst, and Junior SOC Analyst.
About
Enterprise IT foundation with a security-focused direction.
For more than four years, I have supported users and business operations in enterprise environments across Germany and India, including organisations with approximately 100 to 800+ users.
In my current working-student role as IT Support Specialist at Simon-Kucher in Cologne, I support 230+ local employees and users across EMEA. My professional work covers endpoint and user support, Microsoft 365, Active Directory, IT service management, device deployment, asset lifecycle, VPN and network troubleshooting, Network Access Control, and workplace technology.
I have completed my BSc (Hons) Cyber Security and received the final result; the final degree certificate is currently pending. My cybersecurity experience comes from the degree, research, authorised lab environments, and six completed technical projects—not from a previous professional SOC or penetration-testing position.
This combination gives me a practical foundation in endpoints, identity and access, networking, user behaviour, troubleshooting, and operational reliability.
Professional Experience
Enterprise IT support across international and multi-site environments.
My professional experience is in enterprise IT and end-user support. The cybersecurity work shown elsewhere in this portfolio comes from my degree, research, and authorised technical projects.

Featured Projects
Six completed cybersecurity projects with technical evidence.
These projects demonstrate my developing cybersecurity specialization through degree work, research, isolated labs, authorised testing environments, and technical case studies. GitHub remains the deeper technical evidence layer.
Project 01Network Forensics
Network Forensics & Malware Traffic Analysis
Investigated a 600+ MB malware-traffic PCAP using Wireshark, NetworkMiner, and a custom Python PCAP-analysis script to reconstruct command-and-control activity and suspicious outbound behaviour.
Key evidence:approximately 2.47M packets associated with the primary suspicious host, HTTP C2 behaviour, backconnect infrastructure, TLS migration, and potential data exfiltration.
WiresharkNetworkMinerPythonPCAPC2 Analysis
Project 02Malware Analysis
Ransomware Analysis — LockBit & BlackCat
Performed comparative static and dynamic analysis of LockBit and BlackCat ransomware samples inside an isolated Windows lab using PEStudio and Sysinternals tooling.
Key evidence:test-file encryption, ransom-note behaviour, LockBit wallpaper modification, process and file-system activity, BlackCat reconnaissance, and verified sample hashes.

Project 03Security Operations / AI
Cybersecurity Incident Classification — NLP, ML & MITRE ATT&CK
Built and evaluated an AI-assisted cybersecurity incident-classification research pipeline using the Microsoft GUIDE dataset, TF-IDF, transformer embeddings, SMOTE, and ensemble machine-learning models.
Key result:Random Forest achieved 69.28% test accuracy, 0.6963 weighted F1, and 75.96% cross-validation accuracy.

Project 04Network Security
Secure Enterprise Network Design
Designed and documented three Cisco Packet Tracer enterprise-network case studies covering segmentation, routing, firewalls, secure management, DMZ architecture, and encrypted inter-site connectivity.
Technical evidence:original Packet Tracer topologies, router configurations, routing output, SSH configuration, Cisco ASA ACL examples, and site-to-site IPsec VPN configuration.

Project 05Offensive Security
Internal Network Penetration Testing
Conducted an authorised assessment against an intentionally vulnerable lab environment, progressing from reconnaissance and SMB enumeration to web-application exploitation and controlled post-exploitation.
Key findings:SQL injection, SMB account enumeration, vulnerable Webmin 1.984 / CVE-2022-0824, successful reverse-shell execution, root-level access, and remediation analysis.

Project 06Application Security
Secure Coding & Application Security
Developed five secure-coding case studies showing vulnerable implementations, security analysis, remediation, and re-testing across common application-security weaknesses.
Approach:buffer overflow, SQL injection, reflected XSS, hardcoded credentials, and insecure deserialization, each addressed through vulnerability → remediation → re-test.

Skills
Technical skills organised by where I have applied them.
I separate professional enterprise IT experience from cybersecurity tools and techniques developed through my degree, labs, and technical projects. This keeps the scope of my experience clear and defensible.
