Mar Jayson San Agustin

Software Developer

I build incredible products and digital experiences for mobile and the web.


In 2014, as a computer science student juggling a part-time gig in graphic design, I ventured into the world of desktop app design using Photoshop. Little did I know that this venture would serve as the catalyst for a profound shift in my career, leading me towards my true calling in programming and web development.

Today, I'm privileged to apply my skills across diverse projects, working with startups and established industry leaders, and this journey fuels my personal growth, reaffirming that coding applications is where I truly find my passion and fulfillment in the dynamic realm of software development and design.

When I step away from the computer, you'll frequently find me enjoying leisurely walks, engaging in online chess matches, and immersing myself in enlightening documentaries.
