Full Stack Developer

Catsule Corp (2024 – 2025)

Focus: Architecting Resilient Full-Stack Solutions and Operational Security.

This role represents my identity as a freelancer and marked a pivotal shift in my career, moving from IT Operations—where I troubleshot existing corporate systems—to architecting and deploying custom web solutions from scratch. This transition gave me deep, hands-on exposure to end-to-end system resilience, security hardening, and operational integrity—skills that are now fueling my return to Cybersecurity and advanced IT Support.

Early Projects & Mentorship

My journey into full-stack development began under the mentorship of a senior engineer with over a decade of industry experience. Before embarking on larger initiatives, I worked on two real-world applications that helped solidify my technical foundations:

• Clothing Store Frontend: Developed the user interface for an e-commerce platform.
• Internal Stock & Finance System: Built a full-stack solution for a used iPhone trading business to manage inventory and finances.

Key Project: Digital Infrastructure for a High-Traffic Political Campaign

One of my most impactful projects was helping design and deploy the digital infrastructure for Alianza La Libertad Avanza de Córdoba, with a strong focus on performance, availability, and data security during critical campaign traffic spikes.

Building for High Availability: I engineered and deployed multiple campaign landing pages and informational sites designed to withstand extreme traffic.

Security & QA: I collaborated closely with the QA team to hunt down and patch critical defects and potential vulnerabilities. We hardened the application's surface area, achieving 99.5% software reliability before the public launch.

Connecting the Dots: I helped handle the full-stack integration, stitching together frontend services with backend APIs to ensure data integrity and smooth performance under peak load.

How We Worked: We operated within an Agile (Scrum/Kanban) framework. Planning sprints to ensure product integrity and adherence to secure coding standards at every step.

As this chapter came to a close, I chose to transition away from freelancing to focus on more structured, process-driven environments. This shift allows me to concentrate on my academic path in Cyberdefense, deepen my expertise in system reliability and security, and continue growing in roles where collaboration, clear processes, and long-term impact are essential.
