01 — About

A developer who builds for impact.

I'm David, someone who loves building things: web apps, automation tools, and digital products that solve real-world problems. Currently pursuing my Master's in Data Driven Marketing at NOVA IMS, after completing my Bachelor's in Information Systems.

I use modern tools and AI as part of my daily workflow to prototype faster, debug smarter, and ship things that actually work. This approach has helped me build production systems that save over 10 hours of manual work per month.

From automating my family's restaurant operations to founding 44SNKRS, a sneaker resale business I started on Instagram and grew to 220+ pairs sold, I'm driven by impact and continuous learning.
