About Me

I'm a Senior WordPress Developer based in the Philippines. For over 15 years, I've helped agencies build high-performance websites, custom plugins, and scalable digital solutions for clients across the USA, Australia, Finland, and the Netherlands.

From pixel-perfect Figma-to-code conversions to custom themes, plugins, and API integrations, I bridge the gap between design and engineering.
I build scalable web solutions that improve performance, streamline workflows, and create seamless user experiences that support business growth.

What I Can Do For You

Providing end-to-end web solutions focused on performance, design fidelity, and business growth.

01

WordPress Development

Custom WordPress themes and plugins built from scratch. Clean, scalable architecture — no bloat, no shortcuts.

02

Figma to WordPress

Pixel-perfect translation of design files into fast-loading, responsive WordPress sites. What you see in Figma is what you get on screen.

03

Web Strategy & SEO

Performance audits, on-page SEO, Core Web Vitals optimization. Sites that rank and convert, not just look good.

04

Web Design

End-to-end UI/UX design for websites and landing pages. Wireframes to polished Figma mockups — modern, clean, and built to convert.

05

Elementor Development

Agency-grade layouts built in Elementor Pro — no bloated templates, no shortcuts. Complex sections, custom widgets, pixel-perfect on every screen size.

06

Maintenance & Support

Monthly care plans covering plugin updates, security hardening, daily backups, and uptime monitoring. Your site stays fast, safe, and online.

07

Landing Page Development

High-converting campaign pages built for speed and results. From brief to live in days — optimized for Core Web Vitals and designed to drive action.

08

WordPress Bug Fixing

Something broken on your site? I diagnose and fix WordPress issues fast — layout breaks, plugin conflicts, white screens, slow load times, and more.

How I Work

A clear, repeatable process that keeps projects on time, on budget, and stress-free for everyone involved.

1

Discover

I start by understanding your goals, audience, and brand. I ask the right questions upfront so nothing gets lost in translation — no surprises mid-project.

2

Design

Wireframes and Figma mockups first. You see exactly what you're getting before a single line of code is written. Feedback happens here, not after launch.

3

Build

Pixel-perfect WordPress development. Clean, documented code — no bloated plugins, no page-builder lock-in unless you want it. Mobile-first, fast by default.

4

Launch

Full testing across devices and browsers, PageSpeed optimization, then deployment. I stay available after launch — you're never left alone on go-live day.

Common Questions

Everything hiring managers usually ask before reaching out — answered upfront.

Yes. I'm currently available for full-time remote opportunities, freelance projects, and contract work. If you're looking for a senior WordPress developer with experience in custom development, API integrations, and scalable web solutions, I'd be happy to discuss your project or team needs.

I'm based in the Philippines (GMT+8) and have 15 years of experience working with teams across the USA, Australia, Finland, and the Netherlands — so I'm well-practiced at overlapping with different timezones and adjusting my schedule to fit yours.

I can typically start within 1–2 weeks of an offer, depending on current project handovers.

I have a dedicated home office with a stable fiber connection, backup mobile data, and my own dev machine, so I'm fully equipped for uninterrupted remote work.

15+ years of WordPress development (custom themes, plugins, WooCommerce, Elementor Pro), plus HTML/CSS/JavaScript and PHP at an expert level. I'm also actively building my React skillset to work as a full-stack WordPress + React developer, so I can bridge both traditional CMS work and modern JS-driven frontends.

I've spent over a decade working async-first with agencies abroad, so I'm comfortable with tools like Slack, ClickUp, and video standups. I over-communicate progress and blockers early rather than waiting to be asked — no surprises mid-sprint.
