Cybersecurity Engineer & Full-Stack Developer

I am passionate about secure software development, ethical hacking, and leveraging technology to solve complex problems. With a strong foundation in cybersecurity and full-stack development, I focus on building resilient, scalable solutions that prioritize security from the ground up (Security by Design). My journey combines offensive and defensive security techniques with modern development practices, AI integration, and automation to create impactful technological advancements.

3 months
Conducted threat and vulnerability analysis for critical infrastructures, deployed perimeter security, developed forensic analysis tools, and contributed to Threat Intelligence and incident response projects.
Key Achievements: Strengthened security posture for a network with 200+ industrial machines and 100+ workstations; increased investigative efficiency by 65% through automated data collection and correlation, reducing repetitive tasks and enabling focus on high-value analysis.

January 2024 – Present
Designed relational database architecture using Prisma ORM and Node.js/TypeScript for machinery management. Developed centralized SCADA system for real-time monitoring of 200 machines across 12 plants, integrating industrial protocols (Modbus/TCP, S7Comm) and applying ICS/OT cybersecurity.
Impact: 15% reduction in machinery downtime through early fault detection.

January 2024 – December 2024
Developed 5+ security tools in Python for automation and testing. Created StyxLoaderX (C++/Windows API) for advanced threat simulation. Integrated with Elastic Stack for SIEM.
Impact: Achieved 70% reduction in log analysis time via serverless pipelines with Elastic Stack and Python, processing 4GB+ daily logs with <500ms latency for anomaly detection. Developed StyxLoaderX, a modular C++/Windows API framework for advanced EDR evasion using dynamic syscalls, AES encryption, and Process Hollowing.
