Civil engineering student with a genuine interest in structural systems, seismic design, and sustainable infrastructure. I turn what I learn in the classroom into real, buildable designs — and I'm looking to do the same for your project.

About
Building
the future,
one beam
at a time.

I'm a 4th-year Civil Engineering student from San Nicolas, Ilocos Norte, studying at Mariano Marcos State University in Batac City. I care a lot about structural analysis, sustainable design, and making engineering work that actually holds up — literally.

My academic work spans from structural detailing and reinforced concrete design to hydraulics and transportation engineering, guided by the NSCP 2015 and AASHTO standards.

I approach every project like a real commission — research, code compliance, and design integrity first. This portfolio reflects actual coursework and academic projects, not placeholders.

I'm currently available for freelance work — structural drawings, design calculations, AutoCAD drafting, or anything civil engineering related that I can genuinely help with. I take deadlines seriously and I'm easy to work with.
