Projects
2025 - Present
A self-hosted home server deployed on dedicated Raspberry Pi hardware, engineered for network security testing, service deployment and real-time physical insfrastructure monitoring. The setup integrates a custom IoT telemetry module using a temperature sensor and LCD display connected to the server, featuring automated visual and audible alerts (LED & buzzed) when critical thermal thresholds are reached.
2026 - Present
A network-wide ad blocking and privacy solution deployed on a Raspberry Pi using Pi-hole. The system acts as a local DNS sinkhole to block advertisements, tracking domains, and malicious telemetry across all devices on the network. Configured custom blocklists, local DNS records, and analyzed DNS query logs to monitor and secure outgoing network traffic.
2021 - 2021
An autonomous microcontroller-based mobile robot developed to track complex paths using ultrasonic and infrared sensor arrays. Programmed in C on an ESP32 platform, incorporating closed-loop PID control algorithms for smooth motor control and precision and precise navigation. Designed the hardware layout, motor driver circuitry, and optimized sensor polling for real-time responsiveness.
2024 - Present
Active competitive team member participating in global jeopardy-style Capture The Flag (CTF) events, solving high-difficulty [FALTA COMPLETAR]. Collaborates with team members to develop exploits and writeups for international competitions on platforms like CTFtime. Complemented by active hands-on practice on TryHackMe for continuous skill refinement.
