“I had a great experience working with Charles Sia Media. Charles was professional, responsive, and really easy to work with from start to finish. He understood exactly what I was looking for and delivered a clean, well-structured website that matched the brief perfectly. What stood out most was his communication and attention to detail, he kept me updated throughout the process, made changes quickly, and genuinely cared about getting the final result right. The turnaround time was also excellent. If you’re looking for reliable, high-quality web design work, I’d highly recommend Charles Sia Media. Will definitely be working with him again.”

Client FAQ

Frequently Asked Questions

Straightforward answers on working models, timelines, code handovers, and ongoing support.

How do we get started on a project?

We begin with a 15-minute technical discovery call or by reviewing your Figma designs and project specifications. Once scope and milestones are confirmed, we kick off development within a dedicated weekly sprint.

Do you work on fixed-price projects or hourly retainers?

We offer both: fixed-scope delivery for defined builds (redesigns, custom themes, landing pages) and dedicated monthly sprint retainers for ongoing feature development, speed optimization, and technical maintenance.

What makes your custom WordPress development different from agencies?

Unlike most agencies that rely on heavy multi-plugin page builders, we write clean, bespoke PHP templates with custom ACF fields and modular CSS. The result is a lightning-fast site that loads in under 0.5s, scores 95+ on Google PageSpeed, and never breaks during core updates.

Can you collaborate across our timezone?

Yes! We maintain active daily overlap with clients across North America (US EST/PST), the United Kingdom (GMT), Australia (AEST), and Asia-Pacific. Communication happens async-first via Slack, Loom video walkthroughs, and Jira/GitHub.

Do I own 100% of the code and assets after completion?

Absolutely. Full intellectual property, repository commits, design files, and database backups belong entirely to you with zero vendor lock-in.
