Hello, I’m Glenn!
I create core business systems, online platforms and marketplaces.
Here are some of the things I’ve built:
Cash Logistics DPU System and APIs
A secure web-based cash logistics backend system using Node.js and Express built with minimal rework. This reduced required operations headcount by 66%, provides real time visibility to transactions, and increased accountability via a maker/checker system.
Cash Deposit Machine Backend System and APIs
A backend system with APIs for management of cash deposit machines / ATMs. This system allows remote management of the machines while securing transaction data via encryption and strict permissions. Completed with minimal rework and fast turnaround (1 month of development)
Resume and Job Post Parsing
A command line app for comparing the skills in your resume to the skills in a job posting. It's the first step to a future machine learning powered resume app I am making. Behind the scenes, it uses document parsing, web crawlers and tons of regular expressions.
Mobile Application Development using App Inventor (Book)
A programming book I wrote teaching teens how to create mobile apps by using App Inventor by MIT. I used a "learning-by-doing" approach, letting students learn concepts and principles by building the mobile apps themselves. Topics include principles for designing a mobile user interface, event handling for mobile actions
, creating application logic
, and usability for mobile apps.
An Android app that helps people answer their life questions through relevant Bible verses and vetted Christian articles and videos. It's powered by a lot of web crawling and many, many filters. Content is also available online since this generates static pages, and on the web via https://bibline.app
An ecommerce service marketplace in the Philippines that aims to connect buyers and sellers. Grows an average of 29% per year, with 7,000 MAU. Designed and developed the platform itself, wrote most of the content, designed the process flows, and even made an Android webview app for it.
Create Content Offers Instantly From Your Blog Posts
A WordPress plugin that converts long form articles into checklists, which can then be used as a content offer in exchange for the reader's email address.
Bihasa - Reviewers for Licensure Examinees
A mobile-first webapp that makes reviewing for exams fun and social via colorful screens, short snackable quizzes, quests, digital rewards, leaderboards, and streaks. Uses spaced repetition and a databank of past exam questions. (previously named QuizMe)
