Software Engineer | AI Support Engineering
I build software solutions, debug complex production issues, and apply AI-assisted engineering to help teams and customers ship reliable, scalable systems.
7+ years resolving production issues and shipping software as both a support engineer and a developer — PHP, MySQL, JavaScript, API integrations, root-cause analysis. 1,000+ customers helped, 90%+ CSAT, 100+ projects delivered.
Gives an AI assistant direct diagnostic access to a live WordPress site: plugin/PHP info, debug-log tailing, and a guarded SELECT-only SQL tool. Two tools are purpose-built for Gravity Forms support: pulling error-flagged entries and tailing any add-on's log by name.
A Gravity Forms add-on that autofills a job application form from an uploaded resume, live, before submission — extracts resume text, sends it to OpenAI's Structured Outputs API against a strict JSON schema, and maps it onto the form owner's fields.
A Philippine-law chatbot that grounds every answer in live web search instead of training data, to avoid fabricated statutes and citations. Enforces a strict no-invented-citations rule and renders real source links beneath each streamed answer.
Generates a short marketing brochure for any company from just its name and website URL. Scrapes the homepage, uses GPT to identify which links are actually relevant (About, Careers, Company pages), scrapes those too, then streams the brochure back live rather than waiting for the full response. Supports on-demand translation into Filipino, French, Spanish, or Japanese; the translation call only fires if a language is explicitly selected, so nothing is auto-translated or double-generated.
Generates a structured legal case digest (Title, Facts, Issue, Ruling, Doctrine) from a Philippine Supreme Court case URL. A custom scraper strips footnotes and citations and works around a broken SSL chain on the government's own e-library domain; the prompt is tuned to quote the Court's own language and preserve named doctrines.
An airline chat assistant that resolves flight-price questions through OpenAI function calling wired to Duffel's Flights API instead of a hardcoded price table. Runs against Duffel's sandbox, so the assistant discloses simulated pricing; a per-visitor rate limiter guards the API keys on this public demo.
Displays a dismissible, customizable wellness reminder popup (stand up, drink water, stretch, rest your eyes) at a configurable interval. Built with the WordPress Settings API for secure option handling and an MVC-style structure (bootstrap class, settings class, and view), with conditional asset loading so nothing is enqueued unless the reminder is enabled.
Logs every 404 hit and lets an admin redirect any broken URL to a working one in one click. MVC architecture, salted SHA-256 IP hashing, open-redirect protection, and CSV export. CI runs PHP lint, smoke tests, and WPCS across PHP 7.4–8.3.
A lightweight plugin for displaying a customizable announcement bar with an optional CTA button at the top of the site. Built with the WordPress Settings API for secure option handling, sanitized hex color and URL inputs, escaped output, and an MVC-style structure (bootstrap class, settings class, views, and helper functions).
Tracks visitors who start filling out a Gravity Forms form but leave before submitting, logging the last field they touched. Adds an Abandonment tab to each form's settings showing total drop-offs and a per-field breakdown, so site owners can spot exactly where a form loses people.
Automatically adds an estimated reading time (e.g. "5 min read") to posts based on
word count. Settings page for reading speed, display position, custom label format,
and which post types it applies to, plus a [reading_time] shortcode for
manual placement.
Digitizes the official 4-fund ledger system Philippine barangay treasurers use, with automatic balance carry-forward and PDF export matching official layouts. No external JS dependencies; server-side role-based access and a two-signature approval workflow.
A proctoring aid for in-person exams given via Google Forms: detects when a student switches to another tab or app mid-exam using the Page Visibility API and window focus/blur events, flashes a full-screen warning, and logs each incident (plus submission time) locally for the teacher to review afterward.
Drag once per session to define a capture region, then every trigger after that silently re-captures it and saves a PNG straight to Downloads — no dialog, no re-dragging. Handles pixel scaling and canvas cropping by hand since MV3 service workers have no FileReader or createObjectURL.
A space-themed typing game built with vanilla JS and canvas: type falling words before they crash into your station. Game state runs on a single requestAnimationFrame loop with delta-time-based movement, so fall speed stays tied to real elapsed time instead of how often the browser fires each frame.
A countdown timer with a settable minute dial, quick presets, and a chime on finish, built with vanilla JS and an SVG progress ring. I use it to keep Sunday school class segments on time and for timing review sessions.
A multiplication practice game built with vanilla JS: type the answer to pop the balloon showing that fact before it reaches the ground. Balloons spawn into fixed horizontal lanes so they can never overlap or hide one another, with three difficulty tiers (1-digit, 2-by-1-digit, and 2-digit facts) and priority given to whichever matching balloon has fallen furthest when two share the same answer.
An alphabet-learning game for early readers, built with vanilla JS and the Web Speech API: say the capital letter shown on a balloon out loud to pop it before it reaches the ground. A phonetic lookup table compensates for common single-letter mishearings (e.g. "bee" for B), and a keyboard (A–Z) fallback keeps it playable in browsers without voice support.
A two-wheel spinner for picking between two lists at once, built with vanilla JS and HTML5 Canvas. Spin both wheels together, watch the pointer flash the color of whichever slice it's over in real time, then remove a pick from the pool with one tap. My kids use it to randomly assign household chores.
“Glenn is one of those rare people you can count on completely. He's professional, dependable, thoughtful, and takes genuine ownership of his work. One of his greatest strengths is his ability to execute while thinking critically — he never operates on assumptions, and that attention to detail consistently leads to better outcomes. The truth is, I wish we could keep him. Any team that hires Glenn will gain a highly capable, reliable teammate who genuinely cares about the quality of his work.”
“His technical skills were excellent, but what really set him apart was how he paired that with genuine care and compassion for customers, who consistently came away happy. He was the kind of guy everyone wanted to work with — any team will be lucky to have him.”
“Glenn consistently demonstrated a strong work ethic, excellent problem-solving skills, and a genuine commitment to helping both customers and teammates succeed. He contributes positively to team culture and can be trusted to deliver high-quality work. Any company would be fortunate to have Glenn on their team.”
“I had the chance to work with Glenn for more than six years across two companies, Gravity PDF and Gravity Wiz, and I've always appreciated the kind of teammate he is. Glenn brings a lot of care to his work — he's curious, dependable, and always willing to learn or step in where he can help. Any team would be lucky to have Glenn on board.”
“He was always at the top of the class and exhibited excellence with whatever subject we were learning. Glenn's perseverance and focus, paired with his intellect and curiosity, let him overcome adversity without struggle. He's reliable and would serve as an asset to any team he's a part of.”
