"Our checkout was timing out during sales spikes. Wijaya rebuilt the plugin stack, load-tested it properly, and we haven't had a downtime incident since. Genuinely calm under pressure."

Testimonials
What it's like to actually work with him
A snapshot of feedback from clients and teams across web development, WordPress engineering, and organic growth work.
★★★★★
"We asked for a chatbot that could learn from our own content instead of giving generic answers. Wijaya built it, wired it into WordPress, and it's handling first-line support on its own now."
★★★★★
"He set up our analytics and SEO reporting from scratch and actually made the monthly numbers make sense to non-technical people. Organic traffic is up and we finally know why."
★★★★★
"Remote, different timezone, zero friction. He documented everything, flagged security issues before they became problems, and our backups have never been more reliable."
★★★★★
"Elementor performance was killing our Core Web Vitals. Within a week our load time and GTmetrix score both turned around, and he kept it that way with a proper audit dashboard."
★★★★★
"Great instincts for both the engineering and the marketing side — rare combination. He'll push back if an idea won't perform, and he's usually right."
