What I'm looking for

I’m looking for remote opportunities in IT Support, Infrastructure, QA, Automation, or Junior Web Development—where I can apply my cloud, security, monitoring, and automation skills, improve systems with best practices, and document everything clearly.

I’m a Software Development Technologist in training with a strong interest in infrastructure, automation, web development, and quality assurance. I’m building my foundation through Systems Engineering, Software Development coursework, and practical specialization in programming web, databases, and architecture.

In my Network & Infrastructure Administrator experience, I administer and maintain hybrid infrastructures (on-premise, colocation and cloud) to ensure high availability for financial systems. I work with Linux and Windows Server, implement virtualization with VMware, configure monitoring and alerting (Zabbix, Pandora FMS, Pingdom), and deploy web applications using Nginx, Apache, and Docker. I also develop microservices and monitoring probes for payment platforms.

Security and reliability are central to how I operate. I configure and administer Fortinet firewalls and VPNs, lead PCI-DSS compliance processes (v3.2 to 4.0.1), and manage vulnerability scanning. I implement SIEM solutions using Wazuh and Monitor Firstoken, apply security hardening (IDS/IPS and FIM), and support enterprise antivirus platforms.

I complement infrastructure with hands-on automation and web development. I’ve built automations integrating WhatsApp/Telegram/Google services and implemented AI workflows with n8n, and I’ve developed web solutions with HTML5, Tailwind CSS, WordPress, and Filament. As a Co-Founder/CIO, I design automation architectures, integrate CRMs (Odoo), and build SaaS platforms and dashboards—always prioritizing documentation, best practices, and continuous learning.
