Bay Area & Silicon Valley • Custom ACF Pro & Headless WP Engineering

Custom WordPress Development in San Francisco Bay

Q: Why do Bay Area tech scaleups prefer custom WordPress over Elementor or standard themes?

Commercial themes and heavy visual builders (Elementor, Divi) inject tens of thousands of lines of bloated CSS and conflicting JavaScript that tank Google Core Web Vitals and hurt developer productivity. Our custom San Francisco WordPress builds utilize native PHP and Advanced Custom Fields (ACF Pro) with semantic HTML5, guaranteeing 90+ PageSpeed scores, sub-second LCP, and a structured CMS experience that gives marketing teams autonomy without breaking code.

Q: How does ONS Tech collaborate during San Francisco Pacific Time (PT) working hours?

We provide guaranteed daily synchronous overlap during Pacific Time business hours (9:00 AM – 1:00 PM PT). You collaborate directly with senior full-stack WordPress engineers in real time via Slack, GitHub pull requests, and live video sprint reviews.

Q: Do you build Headless WordPress architectures with Next.js frontends in Silicon Valley?

Yes. Headless WordPress is hugely popular among Bay Area startups. We decouple WordPress into a secure headless CMS backend using WPGraphQL, paired with a modern Next.js or React frontend deployed on Vercel or AWS Edge for sub-300ms global page transitions.

Q: Can you audit and speed up an existing slow or hacked Bay Area WordPress website?

Absolutely. We conduct deep code audits to eliminate plugin conflicts, purge database bloat, refactor render-blocking assets, configure server-side caching (Redis, LiteSpeed, Nginx), and deploy Cloudflare enterprise edge caching to bring your site's load time under 1.0 second.

Q: Can you scale WooCommerce for high-volume California DTC brands?

Yes. We engineer enterprise WooCommerce architectures equipped with Redis object caching, custom database indexing, offloaded Elasticsearch/Algolia search, optimized checkout flows, and automated ERP connectors capable of handling high concurrent checkout spikes without server slowdown.

Q: Do we retain 100% ownership of our WordPress source code and custom themes?

Yes, 100%. All custom PHP themes, bespoke plugins, and frontend code are delivered directly to your company's private GitHub/GitLab repository under full intellectual property transfer. We never use proprietary vendor locks or recurring software license keys.

Clean code, high velocity, zero bloat. We engineer bespoke WordPress themes using native PHP and ACF Pro, headless Next.js platforms, and high-volume WooCommerce stores for Silicon Valley startups, venture-backed brands, and Bay Area scaleups.
