About Me

Software engineer and computer science undergraduate at ACLC College of Mandaue with a focus on web and mobile development, automation, and database design.

Engineering Approach

I am currently pursuing a Bachelor of Science in Computer Science (2024–present) at ACLC College of Mandaue in Cebu, Philippines. My core technical strengths and specialization focus on building responsive web applications, native cross-platform mobile apps, performant REST APIs, automation, and database design.

I emphasize writing clean, scalable, and maintainable software designed to solve practical, real-world problems. Whether architecting backend services, crafting responsive client interfaces, or modeling structured data, I value simplicity, performance, and solid engineering fundamentals.
