Excel, Android and Desktop Applications
07/07/2026
IMPORTANT NOTICE:
For clarification, I have been developing and selling personalized PDF files, mobile applications, Excel-based programs, plugins and desktop software solutions since 2018.
My CELE reviewers are intended for students and reviewees who are preparing for the board examination—not for licensed engineers looking to compete in the same market. If you purchased my products and later decided to create and sell competing materials, that is your choice. However, do not expect me to remain silent when my work, effort, and years of development are being used as a foundation for direct competition.
(If found, you will be automatically blocked. I choose peace, and I have no interest in engaging in unnecessary conflict, negativity, or distractions. Ayaw ko naman my competitor freely roaming on my page, then bibili nung product ko, eh ayaw ko naman maging supplier sa competitor ko.)
I also have larger development plans for my past CELE reviewers and educational resources that have been in the pipeline for quite some time. However, I prefer not to disclose those plans publicly until they are ready for release. I believe in focusing on ex*****on rather than making announcements far in advance.
The idea of incorporating an interactive quiz feature into my Civil Engineering Terminologies PDF is part of a long-term development plan for my educational materials and digital products. Every project I release follows a planned roadmap and sequence of development.(Do you think you can encode 1088pages pure text with figures, highly organized in a short period of time? Of course, not! and by the way antagal ko na sa interactive quiz feature na idea, madami nga gumagawa yan,yung iba free pa nga sa youtube)
Innovation and continuous improvement are common practices in any industry. No single person owns the concept of quizzes, reviewers, mobile applications, or interactive learning tools. What matters is how these tools are developed, improved, and delivered to users.
It is also important to understand that technology, programming languages, software frameworks, and development tools are shared resources used by developers around the world. If two products utilize the same technology or programming language, that alone does not mean one copied the other.
Many features, functions, and development approaches are already well-known within the software industry. Developers working within the same field often arrive at similar solutions because they are solving similar problems using the same available technologies.
Instead of seeking public sympathy or creating unnecessary issues, it is better to focus on improving our respective products and serving our customers well. Healthy competition drives innovation and benefits everyone.
I will continue developing educational resources and software solutions for the civil engineering community as planned.
Let's provide whats best for our clients!
