Frequently Asked Questions

What front-end technologies and frameworks do you use?

We specialize in modern semantic HTML5, modern CSS3 (Vanilla, CSS Grid, Flexbox, Tailwind CSS), modern JavaScript (ES6+, TypeScript), and lightweight frameworks like React, Vue.js, and Alpine.js. For animations, we use hardware-accelerated CSS and GSAP.

How do you ensure sub-second page speeds and 90+ Google PageSpeed scores?

We write 100% custom, zero-bloat code without multi-purpose page builder bloat. We optimize the critical rendering path, eliminate layout shifts (CLS), inline essential CSS, defer non-critical assets, and serve modern WebP/AVIF image formats.

Can you translate our custom Figma designs into pixel-perfect code?

Yes, pixel-perfect Figma-to-code translation is one of our primary specialties. We respect your design tokens, typography scales, spacing units, and responsive behavior with exact fidelity across mobile, tablet, laptop, and desktop viewports.

How does direct senior developer collaboration work?

You communicate directly with Chad Sia via dedicated Slack/email channels and video strategy sprints. This eliminates the miscommunication, delays, and markups of traditional agencies, ensuring your project is built with senior precision from day one.
