Projects
A self-hosted home server running on a repurposed laptop, serving as a network security and infrastructure lab. Virtualized with Proxmox and orchestrated via Docker/Portainer, it hosts Pi-hole as a network-wide DNS sinkhole, Tailscale for secure remote access without exposed ports, and a Grafana/Prometheus stack for infrastructure monitoring.
Arduino-based environmental monitoring solution designed to track indoor climate metrics in real time. By interfacing a DHT11 sensor with a 16x2 LCD display, the system processes live temperature and humidity telemetry directly on the microcontroller, providing clear and instantaneous visual output.
2024 - Present
Active competitive team member participating in global jeopardy-style Capture The Flag (CTF) events, solving high-difficulty challenges. Collaborates with team members to develop exploits and writeups for international competitions on platforms like CTFtime. Currently ranked in the top 3% on TryHackMe for continuous hands-on practice for skill refinement.
