What I'm looking for

I'm eager to apply my technical and organizational skills and grow in a challenging cybersecurity, networking, or IT infrastructure role.

I designed the IN-Rail Fence Cipher, an encryption and decryption technique that extends the rail fence cipher by combining substitution and transposition methods.

For my IT device and systems security project, I built a virtual network topology in GNS3 and carried out a brute-force test using Burp Suite in a restricted environment.

I also built a real-time smart irrigation system with Arduino Uno, a relay module, a moisture sensor, and an LCD display. It used cloud weather data to skip watering ahead of expected rainfall.

At IIon's Tech, I developed skills in device configuration, network documentation, and topology design, and provided Level 1 network, software, and hardware support. I later assisted NMB Bank's IT team with day-to-day technical support and troubleshooting.
