IT Instructor and Industry Practitioner. I teach networking, security, and systems from 6 years in the field, not from a textbook.
Now teaching full-time at Richwell Colleges and part-time at ACLC Baliuag, while taking my MSIT at PUP. I translate real-world systems into lessons students can actually use.
Full-time IT faculty at Richwell Colleges and part-time at ACLC Baliuag. I teach networking, security, programming, and systems, and I write my own courses.
Taking my MSIT at PUP on the way to a doctorate in IT. My focus is learning analytics and how IT is actually taught.
Sir Vantes: free Tagalog IT education on YouTube and TikTok, and a resource person on national television.
I spent six years on the front lines of enterprise IT, doing Support and Operations, keeping systems, networks, and end users running. I've deployed and managed fleets of workstations, defended uptime, and dealt with the kind of messy, real-world problems that never show up in a textbook.
Now I teach it full-time. I'm a full-time IT instructor at Richwell Colleges and teach part-time at ACLC Baliuag, while taking my Master in Information Technology at PUP. What makes me a strong instructor isn't theory, it's that I've actually done the work. I can show students how a concept plays out in a live environment, why it matters, and where it breaks.
I teach bilingually in English and Tagalog, and I've worked with learners at every level, from absolute beginners touching a command line for the first time to students preparing for industry certifications.

Invited on live national television as the resource person on super intelligent AI, a twenty-minute conversation with the three hosts. I explained narrow AI, AGI, and superintelligence for a general audience, with two live demonstrations of generative AI tools.
Watch the segmentI teach the subjects I've lived. Every topic below comes with field stories, live demos, and the context that turns memorization into understanding, delivered bilingually in English and Tagalog.
OSI & TCP/IP, subnetting, routing & switching, and VLANs, with hands-on Cisco Packet Tracer labs. Taught as DCN1 and DCN3.
Full-stack foundations: HTML, CSS, JavaScript, the DOM, PHP, MySQL, and OOP with data structures. Taught as Advanced OOP (AOOP).
Core security concepts, threats, hardening, and IT audit and control, with live classroom demos. Taught as IAS2 and the IS elective.
Platforms and operating systems, hardware and computer systems servicing aligned to CompTIA A+, and Living in the IT Era for first-years.
Delivering live IT lessons: slides, whiteboard, and a full class.
Watch a live teaching demo and see how I break down complex IT topics into clear, practical lessons.
Helping senior high students pick the right course and IT students figure out their next move, straight talk, no sugarcoating. New clips every week.
Six years of doing, not just knowing. Grouped by domain: these are tools and systems I've worked with hands-on in production environments.
Hands-on labs and projects, the kind of work I both do and teach.
An adaptive, single-page study tool covering 45 high-miss Network+ concepts across 8 scaffolded modules. Runs in the browser with no sign-in; progress saves locally. Live in the Labs playground.
An interactive encryption and firewall playground built for a live lecture: symmetric vs. asymmetric encryption with a paint-mixing Diffie-Hellman analogy, plus a click-and-drag firewall rule lab.
A full-stack reference website (HTML, CSS, JavaScript, PHP, MySQL) built as the worked answer for my Advanced OOP and Data Structures course, with deliberately broken copies and an auditor script for student defect-hunting.
The reusable attendance and grading machinery I run across both schools: spreadsheet-based, low-infrastructure by design, and built to produce accreditation evidence as a byproduct of normal teaching.
Credentials that back the experience.
