Experience

Three placements, each one ending in something that shipped.

Jul 6 – Aug 21, 2026

On-the-job training — fiber optics & networking

G-Connect Systems & Trading Corp., Malvar, Batangas

240 hours applying fiber optics and networking training on live work: splicing and termination, FTTH deployment, and data center operations.

Jul – Aug 2025

Electronics Engineering Intern

Bandai Wireharness Philippines Inc.

Built an automated internal system with macro programming that cut production time and manual workload.

Monitored the production line to learn the manufacturing workflow, and helped supervisors document daily production metrics.

Apr – May 2023

Work immersion

Negros Occidental Electric Cooperative (NOCECO)

Supported supervisors on daily operations and wrote a macro-based automation to take a recurring manual task off their hands. First time I saw a script save someone real hours.

What I work with

Grouped by what the work actually is, not by logo count.

Hardware & embedded

Arduino Uno, FPGA work in Quartus, and circuit design on paper before it ever hits a board.

Simulation & design

NI Multisim, Falstad, EveryCircuit, Livewire for verifying a circuit, AutoCAD for drawing it.

Code

Python and JavaScript day to day, with HTML and CSS for the front end of everything I ship.

Deploy & data

MongoDB behind the app; Vercel, Render, Railway, and Replit to get it online.

How I work

Independent

Comfortable running with a problem on minimal supervision and coming back with something finished.

Adaptable

Requirements move. I would rather adjust the plan early than defend the old one.

Curious by default

Most of what I know outside class came from taking something apart to see why it worked.

Visual communicator

I design my own diagrams, posters, and slides in Canva rather than waiting on someone else.
