Why Hire Me
READY TO ADD VALUE TO YOUR PROJECT
Cum Laude Computer Science graduate currently working full-time for an Australian digital media company. I've delivered 4 live client websites, have 3 more in staging, and completed 2 mockup designs — 9 client projects total for Australian businesses across healthcare, fitness, hospitality, wellness, and e-commerce. I also maintain 27+ live websites and build my own platforms: a map-first land marketplace (LotAtlasPH), a Philippine salary dashboard (Sahod.io), and an AI-powered recipe app (EatEase). I take on freelance and contract work during off-hours — delivering quality without compromising deadlines.
I treat every client project like my own product — obsessing over performance, clean code, and the details users actually notice. I build for results first: if it doesn't help your business grow, it's not done.

SOLUTIONS THAT DRIVE RESULTS
WordPress Solutions
Your website is the first thing customers see — if it looks outdated or loads slow, they leave. I build professional WordPress sites that convert visitors into paying customers.
Custom Web Apps
Off-the-shelf tools don't fit every business. I build custom web applications with React, Next.js, and Node.js — tailored to how your business actually works.
Speed & SEO
A slow site costs you customers. A site nobody finds costs you even more. I optimize load times, fix technical SEO, and get you ranking where your customers are searching.
Ongoing Support
Broken plugins, security vulnerabilities, expired SSL — one neglected update can take your site down. I handle maintenance, monitoring, and backups so you never lose sleep over your website.
Digital Transformation
Your competitors are online — your customers are searching for you there too. I help businesses go from zero digital presence to a professional platform that captures real leads.
Have a Project in Mind?
Open for freelance projects and contract work. I work remotely and can collaborate across time zones. Whether you need a web app, WordPress site, or custom solution — let's discuss your project. Response within 24 hours.
