• Guided 20+ undergraduate students through hands-on MikroTik network configuration labs, covering routing, switching, VLAN segmentation, NAT, and firewall rule implementation, helping them build practical skills aligned with real enterprise network setups.
• Diagnosed and resolved live router misconfigurations during lab sessions (including routing loops, VLAN mismatches, and NAT/firewall rule conflicts) minimizing downtime and keeping practicum sessions on schedule.
• Fostered a productive lab environment through proactive student support, demonstrating the communication and stakeholder management skills valuable in client-facing or team-based technical roles.

• Conducted offensive security assessments against web applications and Windows-Linux server infrastructure in simulated lab environments, applying PTES and OWASP Testing Guide methodologies across the full attack lifecycle — reconnaissance, enumeration, exploitation, and post-exploitation.
• Performed service and host enumeration using Nmap, Nessus, and manual banner grabbing to fingerprint attack surfaces, then exploited identified weaknesses including SQL Injection, XSS, IDOR, and authentication bypass using Burp Suite, Metasploit, and custom Python/Bash scripts.
• Executed Active Directory attack chains including credential harvesting, Kerberoasting, and lateral movement mapping with BloodHound and enum4linux, identifying privilege escalation paths on Windows (unquoted service paths, DLL hijacking, token impersonation) and Linux (SUID binaries, kernel exploits, cron misconfigurations).
• Chained multiple vulnerabilities to build end-to-end attack paths from initial foothold to domain/system compromise, validating exploitability through proof-of-concept (PoC) development and mapping techniques against the MITRE ATT&CK framework.
• Documented exploitation methodology in technical reports including CVSS scoring, step-by-step reproduction, and supporting evidence (screenshots, logs, command output) to communicate attack narratives and risk severity to technical stakeholders.

• Processed and structured 1,000+ RKKPS documents with zero data loss through manual duplicate detection, classification, and consistency filtering.
• Managing the website and social media, producing 40+ content pieces that maintained a consistent, professional brand image.
• Supported cross-functional information systems coordination across a multi-lecturer, international-scale program with 50+ participants, reflecting the organizational and communication skills needed in fast-paced, collaborative environments.

• Developed and maintained front-end structure and layout, improving navigation flow and ensuring responsive design across mobile and desktop devices.
• Optimized page load performance through asset compression (image optimization, CSS/JS minification), caching configuration, and lazy-loading implementation for heavy content.
• Managed hosting and deployment via cPanel, including domain/subdomain configuration and versioned site deployments.
• Collaborated with the marketing team to design and customize landing pages for campaigns, reviewed page structure for Google Ads compatibility, and provided technical recommendations to improve Quality Score and conversion rates.

• Assisted in conducting practicum sessions based on lecturer-prepared materials, supporting session flow preparation and organization for foundational Microsoft Office modules prior to mid-term period.
• Guided students through hands-on document creation exercises in Microsoft Word, Excel, and PowerPoint, explaining technical procedures in a clear and structured manner suited for non-technical audiences.
• Coordinated with lecturers and students during lab sessions, managing attendance and maintaining an organized and effective learning environment.

• Assisted in facilitating hands-on workshops for 50+ university staff, supporting participants through practical exercises on core features such as styles, table of contents, section breaks, and multi-level lists.
• Helped demonstrate intermediate-to-advanced Word workflows (mail merge, track changes, commenting, and template creation) and provided tailored follow-up assistance to participants with varying proficiency levels.
• Supported the delivery of step-by-step technical instructions by guiding participants through complex procedures and offering individual assistance to accelerate learning and reduce dependency on one-on-one help.
